1905 was a big year for Megacerops. Richard S. Lull, of the Massachusetts Agricultural College (presently UMass Amherst), published his description and plates of a fossil he named Megacerops tyleri in the Journal of Geology for the first time. Thirty five years before that the genus Megacerops was originally named and described by Joseph Leidy. Osborn discussed Leidy's description in his 1902 discussion on the Oligocene titanotheres. Either way, Lull's plates depict a skull and forelimb of the animal, far more than Leidy had in his initial descriptions. Prior to this, in the same compile volume, Lull detailed the restoration of the animal. This restoration was effected in clay and features a photograph of the skull, as opposed to the line drawings in the plates of the description. Papers and studies continue to be published, of course. The last well detailed description of a new specimen that I would recommend reading was published in 1995 in the Journal of Paleontology and introduced the new species Megacerops kuwagatarhinus from the White River beds of Montana.

Walking with Beasts features a battle that is pretty interesting to watch. The confrontation is between Brontotherium (as they are calling it in the show) and Andrewsarchus, an animal known from an enormous solitary skull and thought to be related to pig-like omnivores and potentially whales as well. Regardless, the fight alone can be seen here, with background on Brontotherium. The entire episode is hosted on a different site. However, it may be worth watching to see what other information the BBC presented on these two animals and the other animals that lived at the same time.

Megacerops, under either that name or Brontotherium is a popular fossil mammal. Multiple sites exist that host lists or paragraphs of facts. About continues to use the more popular Brontotherium on their site while Planet Dinosaur acknowledges the switch, somewhat begrudgingly since they use both names on the title of the page. Brontotheres as a group are addressed on a page dedicated to the fossils of the White River Badlands rather than any single genus in the group. This wider angle approach is good at times and is helpful for viewing all of the animals related to this animal rather than just looking at our target animal. It is always good to look at the bigger picture once in a while.

Though not a rhinoceros and much more closely related to horses, Megacerops was a very rhinoceros-like relative of horses and is therefore a bit confusing on first glance. Known more popularly as Brontotherium, Megacerops Leidy 1870 was far larger than any modern horse or rhinoceros. Its distinctive look, two large bony protuberances above its nose, make it look slightly more like a rhinoceros, but are significantly different from any known rhinoceros horn as well. The use of these protuberances is well documented, as we shall discuss. This animal is yet another North American Eocene mammal.
