TerahB Posted December 5, 2022 Share Posted December 5, 2022 Hello Could someone please give their opinion regarding if this an authentic Ceratopsian bone? Per the seller it’s from Wyoming. Thank you! Link to comment Share on other sites More sharing options...
Troodon Posted December 5, 2022 Share Posted December 5, 2022 You should ask the seller how he came to identifying it as Ceratopsian. No diagnostic features to say much. Did the seller even provide a provenance? 1 Link to comment Share on other sites More sharing options...
hadrosauridae Posted December 5, 2022 Share Posted December 5, 2022 Don't hesitate to contact a seller and ask about provenance. They should be able to to tell you the area and formation it came from, the general age, as well as their reason behind the label. While these random, broken chunks of bone can be very difficult (if not impossible) to ID, the diggers are usually familiar with the species of the formation in their area, and differences in morphology. On top of that, some formations, like the Hell creek or Lance are predominantly filled with ceratopsian material, making a general id of ceratopsian vs theropod etc, much easier. 1 1 "There is no shortage of fossils.

TerahB Posted December 5, 2022 Author Share Posted December 5, 2022 The listing does say this FORMATION Lance Creek Formation, Wyoming The Lance Formation was first named and officially described by John Bell Hatcher in 1903 for exposures along Lance Creek, Wyoming. Prior to this time it was simply referred to as the “ceratops beds”. Does that help? I can definitely ask for more information if that would be helpful. Thanks for your help Link to comment Share on other sites More sharing options...
Troodon Posted December 5, 2022 Share Posted December 5, 2022 Okay at least we know it's from the right deposit. BTW its Lance Formation not Lance Creek. Again the fragment does not have any features to say much. I would contact the seller and find out how he arrived at that ID. Let us know. Link to comment Share on other sites More sharing options...
TerahB Posted December 5, 2022 Author Share Posted December 5, 2022 Here is their response Flat bones are usually a representation of a ceratopsian. They know this because there were herds of them that all dies at once. It is very generalized. I hope that helps. Link to comment Share on other sites More sharing options...
Troodon Posted December 5, 2022 Share Posted December 5, 2022 Interesting I collect in an hadrosaur bonebed and have lots of flat bones. " It is Very Generalized" ??? Look believe what you want I have not seen anything that convincingly says its ceratopsian. Wanted to hear the fragments came from a beat up skeleton or busted up known bone. 1 1 Link to comment Share on other sites More sharing options...
TerahB Posted December 5, 2022 Author Share Posted December 5, 2022 Yes that makes sense, I’ll probably pass on the bone. Thank you for your help. Link to comment Share on other sites More sharing options...
