Popularity Ruins Dinosaurs Anyway

Sinraptor, again like other Chinese dinosaurs, is just not that popular in the regular mediums; there are no dedicated children's books, no documentaries where it is considered a key player, and it is only mounted as a full skeleton in a very small number of museums. It has however, made it into the realm of toys

From the Carnegie Collection

and also into the collectable card game market, as we mentioned before here on Monday.

Where he looks fairly awesome

One of the the most important things to remember about this Late Jurassic predator is that, even though not particularly popular, they are the ancestors to more known theropods such as Giganotosaurus and Carcharodontosaurus which makes it quite a big deal even if Sinraptor itself isn't very popular.

June is Bird Month, so be prepared tomorrow for a lot of feathers!

500th Post!

I know I said that once before, but I erased some none dinosaur posts, so this is officially the 500th dinosaur post.

Sinraptor's body is typical, we have gone over that, for a theropod. The adult was about 10 feet tall, 25 feet long and was pretty lithe as far as its belly is concerned meaning that it most likely did not weigh a whole lot like an herbivore the same height and length would have. The original skull was found to have "a variety of gently curving tooth drags or gouges, shallow, circular punctures and one fully penetrating lesion." The teeth were not anything particularly special, they were fairly expected to be what they are when you look at them. The fact that this dinosaur has three decent claws indicates that these claws may have been used fr either grasping or slashing. They are not the enormous attacking claws of an Allosaur but neither are they the tiny underpowered hand claws of a Ceratosaur. There is not too much extraordinary about it, I am sad to report, so today seems like a really short entry. Oh well, it happens!

Trying to Read Papers is Difficult

Some days you have better luck finding truffles in a city park than you do a full length scientific paper (see LitToC article here). I have a few good abstracts to share though, and that is far better than nothing as it gives you a fairly good idea what the papers are about. Additionally, I wanted to note that I was re-examining the new Paul book, as I often do, and found it interesting that not only does he not recognize Y. hepengensis, Y. magnus, and Y. shangyouensis as separate species, but he places Sinraptor into the Yangchuanosaurus genus effectively eliminating the Sinraptor genus entirely. Interesting for sure. The abstracts that I wanted to share today are from Currie and Zhao's original naming paper

A new carnosaur (Dinosauria, Theropoda) from the Jurassic of Xinjiang, People's Republic of China and from another paper, which really only mentions Sinraptor, but is interesting in that it is about finding a fossil in Thailand that dates from around the same time. This new animal was placed in the sinraptorid family and thus may be very closely related to Sinraptor and Yangchuanosaurus so this paper would make a rather interesting read if we could access the entire paper as well. Perhaps someday we will be able to find more open sourced material, until that time we will have to make do with what we have. I'd be more in depth but I have to go do adult things today as someone hit my parked car yesterday.

Motion Monday

I know I typically call it Movie Monday, but there are not, as I have noticed many times the past month, actual movies and very few documentaries which mention Chinese dinosaurs. Additionally, I would like to once again welcome new readers and thank profoundly all of the old readers as we have, for the first time ever here at Dinosaur of the Week, had an 8,000 plus viewing month! There still being four days in the month I would not be amazed if we got well over 9,000 but I am amazed and happy that I have reached that much of an audience already in the past month.

Monday though. We have a lot of short little user made videos that show very different interpretations of Sinraptor and we also have a few "tribute" videos we can choose from today. The good things about these "tributes" is that they have a lot of different illustrations of the animals, the bad thing is usually that the music is usually some type of numetal horror story that I cannot stand, sorry video makers, I do not like the music you usually pick, I admit it. That said, let us look at a few good examples of Sinraptor videos, "tribute" or otherwise.

It's rare that a dinosaur does not make it into a Dinosaur King reference. It may not be everyone's favorite anime, but it does happen to cover an enormous spectrum of paleo-animals. The first half of this video is a Sinraptor animation, the second half is being mean to a ceratopsian.

Again, the music is not to my taste, but if we're trying to find something I don't like about lots and lots of visuals of a dinosaur than all I am going to complain about is the music. Maybe I'm just stuck in the 90's when it comes to heavy music... and rap... and some other kinds of music.

As far as the tribute videos go, one of the most prolific makers of these videos is this guy: Archosaur King. I think, actually, he's one of the few people that uses music I can't complain about and I like that he finds a lot of images that are not your typical images from a Google search. It's worth the 6 minutes though to see all the different representations.

We All Need To Learn Somedays

My longest posts are usually Saturdays because I do the illustration thing and I have time to look them up, but I have recently contemplated switching Tuesday and Saturday... but I may not do it. Regardless, I learned some things this morning about yesterday's post and that's what we are here for; to learn and grow together, as PBS as that may sound to some people. I am not, yet at least, a "professional" paleontologist and I have not until summer before last followed academic papers and such, so I am thankful that the paleo community is filled with such nice people that don't throw my occasional oopsy back in my face but show me why I was wrong and where the correct info is.

That's important to address today because I always devote Sundays to family time. Learning about something new with your children or other young relatives and even just taking the time out to sit back and color or read a book online or that you find at the store thanks to our ability to find it online and share it with one another on here. Anything really, so long as the involvement with the blog today is stressing relaxation and casual learning and fun as a family, no matter what kind of family you have. I guess we should get into it today then. Sadly Dinos for Kids and Kids Dinos do not have pages up for Sinraptor, which is okay. There is an abbreviated children's encyclopedia entry that everyone can read together though. I found a neat 3D coloring book as well, and it's not too expensive, but you'd have to order it online. Supposedly there's some Sinraptor in there, but even if it's just dinosaurs in general, that's a good present for your younger family members (or yourself!). As far as actual coloring sheets are concerned, they just don't really exist, so I recommend searching Google for black and white images or just following the search I did works too. There are a number of books and toys, but the books are all encompassing and I'll wait until Thursday to share toys with you. Have a good day relaxing and learning everyone!

The Faces of Sinraptor

©Currie and Zhao (to the best of my knowledge)

Sinraptor is a theropod. There, I have almost completely summed up the entire illustrative world surrounding Sinraptor. All kidding aside though, Sinraptor has always been portrayed as a general dinosaur. Very typical lines and hands and face, never anything truly unique about it. In fact, the illustrations I did find that are unique took me a good deal of searching deep down in the bowels of the internet. The hands on the model here are a little broken looking honestly, but they are not that bad. The other images I dragged out are intriguing for a variety of reasons which I will get into shortly. The artists featured this week are Brett Booth and Brian Engh. I like finding artists new to our little community here and this week, I have succeeded very well. Plus all that delving into the fathoms of the internet trying to find something atypical and interesting for Sinraptor led me to new websites I have yet to mine for dinosaur gold.

©Brian Engh

Let's start with the face of Brian Engh. The face of Sinraptor by Brian Engh, I mean. I trudged around his site a bit this morning to get a feel for his art and that's normal routine for me. I know I do not really talk much about getting to know the artists unless we have a good conversation about the art (like I did with John Bindon a while back) but I felt that Mr. Engh's Sinraptor deserved a bit of justification because I know a lot of purists may balk at the eyes of this dinosaur. The nasal/prefrontal ridge is a wonderful character addition, as the skeleton does not imply its existence, and its inclusion here simply makes for a much more interesting and individual theropod as opposed to the usual variety that the word theropod creates in our mind. The same goes for the quill like protuberances about the neck and bottom of the mandible. The eyes, however, are right in line with Mr. Engh's other work and, though not the normal version of eyes we see in dinosaur illustration, convey emotions beyond the simple reptilian eat to live and lack of empathy and sympathy and even intelligence standpoint from which dinosaurs are often viewed.

©Brett Booth

Brett Booth, on the other hand, gives us a fairly normal body for a theropod, but as I said before, there is a specific reason I chose these two illustrations for today. I'm not knocking his illustration, not in the least bit. The eyes and head and body are very dinosaur, not much emotion, but the mechanics of it are what I want to highlight here. The typical running pose we see everywhere, but there are few times we see it from anywhere but from the side on and the times when we do see a theropod from either front or back, they are typically standing still or walking and frozen in a moment where the feet are on or about to leave/touch the ground. Regardless, the toes are already splayed and ready to meet the ground (linked image is ©Gregory Paul from a discussion by Scott Person on tail depiction found on Art Evolved). Here, however, Mr. Booth has given us an image of an active predator which is certainly interested in something or tracking some morsel and has picked up its foot allowing the feet to relax enough so that the toes are no longer splayed out. Your own feet do this to a much lesser extent, in case you haven't ever looked at your toes when you walk. It's a balance thing and relaxing the toes when they lift, if it does anything specifically, allows them to easily clear objects and not kick the dinosaur's own leg with its massive toe claws. Seeing it as we rarely do in an illustration is wonderful and shows a range of mechanics in this Sinraptor which we typically do not see in dinosaur illustration, which is wonderful and worthy of our praise and admiration as well.

Chinese Thieves

Quick question: is it possible to have a more sinister translation of a name than "Chinese Thief"? I believe the answer is yes, when the name not translated is Sinraptor, you are already sounding pretty devious. A carnosaur, Sinraptor dongi, and purported second species Sinraptor hepingensis, make up a rather small genus of Chinese Late Jurassic animals which have also lent their name to a family distinction, the Sinraptoridae, which also includes the genus Yangchuanosaurus. These large theropods are not related to the little dromaeosaurs often referred to as "raptors" or any other dinosaur with raptor in the name such as Oviraptor. Few remains have been found and those that have been found are on display or stored in China and have been such since their discovery in 1987.

Never Popular Chinese Dinosaurs

Majestically posed on a rock

Despite being a Chinese dinosaur, which does seem to be a handicap to the popularity of many animals that we have seen from China in the past, Huayangosaurus actually does seem to have a bit of a following out in the world in different places. There are toys, video game references, books, even an independent animation, which looks like it may have been a school project but is very well done, and of course papers and illustrations of Huayangosaurus. The only good toys I could find are made be Kaiyodo and can be found on ebay if nowhere else. I did find about a million shots of that one toy though.

Overhead shot, Huayangosaurus on far right. Look at those spikes

 I also found Zoo Tycoon references for Huayangosaurus on Youtube. I would rather link it today so it goes directly to the Huayangosaurus. Finally, I have for you, the short animation sequence. As I said before, very well done, and it looks like it was done for a class, but awesomely done for a class if that be the case. The sound is a little much, I won't lie, but it looks good.

Huayangosaurus Was Discovered When I Was Discovered

The twelve original specimens were unearthed in 1982, the same year I was born, that is pretty interesting and a small fun fact. Unfortunately, none of those twelve individuals consisted of complete specimens. The fact that twelve were found all together is, in itself, quite intriguing. Typically we don't see Stegosaurus traveling in herds in the fossil evidence or in the documentaries we have available, however, is it possible that Huayangosaurus was a herding animal? I wonder if this has been looked into or if it is considered a washed out area where bodies collected during a flood or something. Then again, if it was a wash out from a flood there would be other dinosaurs present too, so I may have just answered that question for good. Regardless, they collected for some reason and sudden death in a flood or mudslide or avalanche could account for this, I cannot tell anyone what it was because I have not found mention of the soil particulates that made up the rocks of the find, and this collection, I am willing to bet, was, if not herding behavior, at least a giant get together for the purposes of little stegosaurian love.

A note about the anatomy of this basal stegosaur. Huayangosaurus was placed within its own family on account of its rather basal skeleton, which we previously glossed over vaguely. The spikes on the shoulders I think we have covered more than enough of this past week. The skull, though, to the right, we have barely mentioned other than to state that it is very basal and almost resembles that of a nodosaur. After I made that comment I checked the group's tree and realized, though I still have not found an "official" opinion which backs up my assertion, that the head probably looks this way in part because it is so basal that it represents the first species on the stegosaur branch of the tree after stegosaurs and ankylosaurs began to evolve away from each other. Should that prove correct, and anyone that can back me up or disprove it is more than welcome to chime in, then I would feel pretty darned awesome about it. However, there is more than a neat theory behind the skull. The skull itself has premaxillary teeth, a trait not found in stegosaurs. Early nodosaurs also have some small evidence of premaxillary teeth prior to the beak adaptations of ankylosaurus and later nodosaurs showing in the fossil record.

Paying for Publications

Huayangosaurus does not believe in free publication. Actually, that is not completely true at all. scientific journals do not believe in free publications and pretty much all of the quality papers on Huayangosaurus are in scientific journals; you cannot really fault company for wanting to protect the rights of its authors and to cover its publication costs. That explained, let us share the abstracts today and if you have your own subscription or want to buy a single article, well you don't need me to tell you that it's okay obviously. The first one I found I can actually look at and I have shown everyone the edition of the Journal of Vertebrate Paleontology that the paper resides in; a paper on Germanodactylus shares its pages which we discussed previously. If you're not a member of the SVP you can still read the abstract here but if you are, and this is my personal opinion, I recommend opening the PDF via BioOne rather than Taylor and Francis. I always seem to have trouble with T&F telling me I didn't pay for the article even though I'm signed into the SVP site and got there from the SVP site. Basically what you're looking at there is a revamped description of Huayangosaurus done in 2005-2006 which redefines the skeleton a little bit, tweaking previous observations and making new inferences pertaining to the structure of Huayangosaurus' body. In a slightly older, about 14 years older actually, paper also in the JVP, which I cannot get my hands on because they are not backdated online that far, Paul Sereno and Doug Zhimin took a look at the skull of Huayangosaurus and analyzed the clade diagnosis of all of stegosauria using Huayangosaurus as the basal model. That's my impression at least, without reading the entire paper we cannot say for certain of course. If anyone has a copy feel free to let me know, or write in your own opinion of it and we can share!

Moving Huayangosaurus

Apparently Australia loves animatronic dinosaurs. I found two videos of Huayangosaurus in Dinosaurs Alive! exhibits in two separate locations; Sydney and Adelaide for anyone keeping track.

My favorite part of the one above is the kid at the very end yelling "There's a dinosaur! There!" The other video is the same thing, obviously, but at a different angle, which is helpful if you want to see the details of the model that was created for the exhibit. It's only the head that is shown, however. Great details in the skin and face though, so it's worth a minute of your time.

There really are no actual documentaries which mention Huayangosaurus, again I say we should call for a series on Chinese dinosaurs, and, to my knowledge, there is no mention of them that I can find on Dinosaur Train, the Nickelodeon dinosaur show, or videos of appearances in the Dinosaur King cartoon. Once again, however, I certainly welcome updated information like I received Thursday last week, so if anyone knows of a good video, send it to us to update this entry!

I Get Smarter

Yes kids of the world, yours truly can learn to do things a new way some days even after two years of doing things the hard way. First, our friends at Kid's Dinos have a page to share on Huayangosaurus for your reading pleasure. I still love their little maps and graphs for the kids to look at. I also found an excerpt available online from the National Geographic "Dinopedia" that was designed for kids that is all about Huayangosaurus. Now, on to what I thought of. I really shouldn't say learned, because I knew how to do this before, I just never thought to do it before today. In my search for coloring pages for the family to have fun with I finally had the brilliant idea to search the images on Google in black and white. Why this never occurred to me before today, I do not know, but I found some good ones to share with everyone today! Bear in mind that Huayangosaurus is not really a high demand dinosaur, so the pages I have that you can color today 1) belong to another person and 2) is not very professional.

Skeletal Blueprint

Huayangosaurus is a tiny bit of a mystery. Some sources state that there are spikes held horizontally at the shoulder (and most illustrations go with this model) while some say they are held horizontally at the hips. Gregory Paul has drawn skeletals with and without spikes attached at the shoulders as well. The thing that gets me here, however, is that I have yet to find a displayed skeleton with a prominent spike at either position. There is, in some instances, a visible extension of the scapula which may or may not constitute the core of this rear facing and not entirely horizontal spike. If that is what the idea of the spike is based off of, I accept that completely, but I do not see the giant spikes jutting out enormously that we see in illustrations. In fact, the spike looks tiny and even with an outer keratin sheath while alive the spike would not have added to the frontal girth of the animal much. Any thorn can hurt, as most anyone can attest to, but this certainly does not look as dangerous as it does when illustrated. The skull of H. taibaii is very basal in its likeness to what we think of when we hear the name Stegosaurus. Their skull almost looks more like that of a nodosaur or ankylosaur at the angle presented above than it does like any other stegosaur. It's not a case of wrong head wrong body though, that is simply how far back down the line Huayangosaurus is on the stegosaur family tree. The plates are also smaller than other stegosaurs, though not small and eccentric like in the African Kentrosaurus, and this gives the animal the look of being a juvenile Stegosaurus. However, we know quite well that this is not the case, that it is in fact just the smaller (15 feet as opposed to 30 feet) adult of Huayangosaurus. Such an evolutionary pattern makes sense in a world in which the predators were evolving larger stronger frames over time to grapple with the larger sauropods. Had the stegosaur family not followed suit by bulking up and growing longer and taller, they would have been too easy to pick off for predators such as Allosaurus and Yangchuanosaurus. Gasosaurus, a 13 foot long predator of Huayangosaurus, attests to this proportionality battle between predator and prey (another prey item at the time in China which was large and heavily populating the land was Shunosaurus at 31 feet and 3 tons which is small for a sauropod). One more thing that is key to identifying Huayangosaurus is the tail. Unlike Stegosaurus, which had its tail spikes oriented more toward the lateral line of the tail and extremely rear facing, the spikes of Huayangosaurus are more central and vertical. A small bony club nodule also ends the tail of Huayangosaurus whereas later stegosaurs do not possess this bony nodule. This is one more instance of evidence of the divergence in evolution of stegosaurs from their cousins the nodosaurs and ankylosaurs.Personally, I am much more of a marginocephalian (horns, frills, and domed skulls) person typically, but looking at stegosaurs and ankylosaurs a lot since I have started this blog has made me really come to love their families (also known as the thyreophora) as well.

Newly "Invented" Species

Basal stegosaurids. Not really "invented" so much as evolved, but a new family, even through evolution, is technically an invention of life and in China was born a new family, the stegosaurids, and their first member appears to be Huayangosaurus. Huayangosaurus taibaii is named after a poet, specifically, and an alternative name to the province of Sichuan which is Huayang, generically. This, like many other Chinese stegosaurs, is often portrayed with shoulder spikes. I am looking into this. Huanyangosaurus lived 20 million years before Stegosaurus in the heart of the Jurassic of China. He was a tiny guy, 4.5 meters (about 15 feet), and had a unique tail arrangement. His plates were smaller than other stegosaurs and the spikes mentioned are typically portrayed at the shoulders but have been mentioned as being on the hips as well; we all love a little mystery.

Popular Culture Day

Yangchuanosaurus has many popular culture outlets borrowing its image detailing its facts. Some not in a very detailed way; for instance Dinosaur Train so far has only used the animal as part of its alphabet song. Dinosaur King, as almost always at least, has also used Yangchuanosaurus as the basis for five cards in the card game as well as appearing in the after school cartoon. They also figure into the Dinosaur King video game as well. speaking of video games, there is an entry from Spore, as we typically see. I think this one is done fairly well. There are toys and books as well, as we have seen, the books I mean. Safari's Yangchuanosaurus is peculiarly scratching it's face (or trying to smell his hand, I'm not sure). There are a ton more toys and books out there to find, and more popular culture references, but these lot above I think are the best available to us to share today!

UPDATED

The Dinosaur Train A To Z/Classification Picnic was recently put on TV and I did not know it, sadly. Yangchuanosaurus sounds a lot like George Takai, and that makes me happy. You can watch it in four parts on PBS' website.

For the first time ever on the Dinosaur of the Week blog, we want your input as to which animal we should cover next week! Vote now and be heard!

Species of a Sinraptor

Y. shangyouensis came from a skull and assorted skeletal bits, as most dinosaurs do unfortunately. Y. magnus was nearly the same, but much larger. Y. hepingensis is not even considered a species by some that belongs to Yangchuanosaurus, but is considered to be a second species of the genus Sinraptor; which for the moment only contains definitively Sinraptor dongi. There are conflicting arrangements of Y. hepingensis in many places. Gregory Paul considers it a distinctive species of Yangchuanosaurus in his newest publications with the other two species representing one species in different stages of growth while many others have taken to calling it Sinraptor hepingensis. It's rather astounding how much confusion there is. There may very well be an official answer, and it does look as though that answer ends in the Sinraptor genus, but if it does, no one told all of the websites and even some official sources. Paleontology just has too many squabbles over ideas and theories without ways to prove some of them definitively, and that is okay in the end.

Late Post

Today I woke up nearly 45 mins late, so I apologize that I am just now sitting down to post today. However, I have a good paper and a "vintage" book. It was published in 2009 but the art looks somewhat vintage. The paper I found names and describes the new species, doubted by Paul, Yangchuanosaurus hepingensis. This is a very descriptive paper that has a lot of good illustrations and goes into good detail about the new species. The book is called Dinosaurs Through Time and is by Nicholas Harris. The book is factual, but a little vintage in the art department, but it looks pretty good and engaging for young readers. I suggest looking at both of them though.

China, A Documentary Please!

Yangchuanosaurus suffers from the same fate as nearly every dinosaur from China. Save a few megastars like Velociraptor and the early birds found in China, there are very few Chinese dinosaurs that actually make it into key performances in documentaries. That does not mean that Yangchuanosaurus has never been talked about on film. In the Brookfield Zoo a few years ago there was a campaign run to vote for the most likeable dinosaur statuary in the zoo. The contest was labeled "Mesozoic Idol" and launched mainly through Youtube videos. Therefore, we have one from the Brookfield Zoo available to us. They dressed up the statue in 80's leg warmers, it's a little strange and they did happen to mention the song I keep thinking of when I say Yangchuanosaurus, so enjoy the minute of fun.

The other video I found is very short on information and then has about a minute's worth of info on TerraNova, the short lived Fox show. Sad that it's gone, buuuuuut it wasn't the best cancelled scifi show I've ever watched, so on with the dinosaur information:

Mother's Day in the Dinosaur World

Yangchuanosaurus, if she was anything like we believe Allosaurus and other large theropods were like, probably cared for her young until they could at least hunt for themselves; less than a year most likely. Now, of course, that does not take into account the idea that theropods may have acted as modern birds do in some ways with flocking habits which would incorporate the young into the flock as soon as they were able to join the general movements of a flock, but who knows for sure if theropods were like geese or hawks? They may have been like either or neither; someday maybe we will get to find out, but perhaps not. I hope they're more like geese, but still, who knows.

Anyhow, what I have for today is sadly devoid of coloring, which may be okay because, it being Mother's Day, you kids may not have much time today to sit and think about dinosaurs. So what I do have to share is three child friendly, quick and easy to read sites for learning. They are:
1) Kids Dinos
2) Kids Dig Dinos
3) Enchanted Learning
