I love original descriptions. That has probably been said many times over. I hate when they are not available for free to anyone and everyone (because it is hard to get articles for some of our younger readers). Despite that happening, there is an absolute mountain of work out there on Paraceratherium. This is due in part to the fact that there are more than a handful of junior synonyms for this animal, meaning that there are a fair number of initial description papers for these now dubious names. There are also new remains still being discovered and described under the currently accepted generic name as well. Rather than listing out hundreds of papers today though, I am encouraging the audience to instead check out, inter-library loan, or even buy a book! This is not because I love mammal paleontology or specifically the work of the author (though anyone into fossil mammals knows the name Prothero), but because anyone that is really interested in Paraceratherium and its family would enjoy and get a lot from Donald Prothero's book Rhinoceros Giants: The Paleobiology of Indricotheres. The first link to the book is a Google powered preview, but this link right here goes to the Indiana University Press. Why would I encourage anyone to buy directly from the publisher instead of shopping around (assuming that purchasing is the intent)? The answer is actually a matter of savings. The publisher is offering the book electronically for $8 less. I love the smell and feel of a new book (almost as much as an old book), but sometimes less is more. You can carry an electronic copy more easily as well. Regardless, I cannot say I have read through this entire book, but the reviews I have seen and the snippets I have previewed point to it being part historical, mostly technical, but very informative overall. As a collector of subject literature (e.g. I get books about birds and dinosaurs whenever I can to compare the information presented regardless of author) I have to say, even if you do not agree with the author, this is a comprehensive work on the animals we have been discussing all week and well worth the investigation on your part! Plus, check out the head on the Paraceratherium on the cover. Pure gold!
