LordTrilobite Posted October 7, 2015 Share Posted October 7, 2015 (edited) Fantastic pieces as alway! My first specimen to share is what I believe to be a Euopcephalus sp skull. The very front end is reconstructed so I'm not 100% positive. Around 15" (38cm) SquareEuSkull1B_edited-1 copy.jpgEuSkull1A.jpgEuSkull1.jpgCondyle EuSkullCond.jpg You know. It might be possible to put a species on it, even with the front missing. A while ago there was a study on Euoplocephalus skulls that looked at the armour plating on the head to identify the species. It mihgt be just as easy as looking at the layout of the armour. I forgot what the paper was called. But it might be worth looking up. Here are a few images from it. EDIT: Found it! http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0062421 Edited October 7, 2015 by LordTrilobite 4 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Runner64 Posted December 26, 2015 Share Posted December 26, 2015 Is there a way to identify Leptoceratops teeth? Leptoceratops has a single root while most ceratopsians' teeth have 2 roots coming off a single tooth. 1 Link to comment Share on other sites More sharing options...
Troodon Posted December 26, 2015 Author Share Posted December 26, 2015 Is there a way to identify Leptoceratops teeth?Yep, like Runner64 said they have a single root and one that is typically more vertical than horizontal. However, sometimes the root is missing or I believe there are a couple of jaw positions of other ceratopsian that also have single root so you also need to look at the crown. Most North American Ceratopsian have a triangular shaped crown with a strong ridge down the center. Lepto's have more of a U shaped base, a flatter tip and a center ridge that is not has pronounced. Here are some examples:Triceratops Leptoceratops This is what you typically see sold, unerupted teeth A maxilla section with a couple of Lepto teeth that are erupted. 3 1 Link to comment Share on other sites More sharing options...
Runner64 Posted December 31, 2015 Share Posted December 31, 2015 Is there a way to differentiate Einiosaurus teeth from other ceratopsians from Two Rivers? I doubt it, but just curious. Link to comment Share on other sites More sharing options...
Troodon Posted December 31, 2015 Author Share Posted December 31, 2015 (edited) You are correct unless they are found with other diagnostic bones you cannot tell them apart Edit: BTW the teeth I have were found in an Eino bone bed.

Runner64 Posted December 31, 2015 Share Posted December 31, 2015 You are correct unless they are found with other diagnostic bones you cannot. Edit: BTW the teeth I have were found in an Eino bone bed. Thanks, I've been looking for one and I see some up for sale on some websites. As a follow up question, does this mean that all Triceratops teeth have the potential of belonging to Torosaurus and Tatankaceratops? Link to comment Share on other sites More sharing options...
Troodon Posted December 31, 2015 Author Share Posted December 31, 2015 Yes if you go along with the premise that those species are valid it would be difficult to distinguish between the teeth. Jury still out and the debate will continue with paleontologists. Link to comment Share on other sites More sharing options...
Troodon Posted March 14, 2017 Author Share Posted March 14, 2017 Have not added to this Jurassic Park post in quite a while. Recently picked up this Tyrannosaurid foot claw. It comes from the same Quarry that Bambiraptor was discovered which is pretty cool. I'm leaning toward this being a Daspletosaurus sp. simply because of size. I've yet to see a Gorgosaurus with that size foot claws and the evidence is mounting that Albertosaurus was not in this fauna, but who knows. 8 4 Link to comment Share on other sites More sharing options...

Troodon Posted December 18, 2017 Author Share Posted December 18, 2017 Updated a few photos, rainy day, first in months. Bones from a Hypacrosaurus site with infant material present. Associated Fragment of Maxilla and infant Foot. Bones are quite distorted and in positioned for best photo Ungual in above Photo. Reluctant to do any additional prep on ungual, very fragile and super rare. Not replaceable. Humeri not associated Femur Tibia 4 1 Link to comment Share on other sites More sharing options...
