jpc Posted December 28, 2020 Share Posted December 28, 2020 it might be that this one has a few holesi n it... those might be ankylosaur traits rather than ceratopsian.... ? @troodon? 1 Link to comment Share on other sites More sharing options...

Allo fifi- It was meant to have a comma and some more words: "thank you for the help! I really appreciate it, man!! " Man, in this case is slang and means friend, but it is much more than that. It is a word suggesting emphasis. Very difficult to explain to someone for whom English is not used everyday. It has no gender. I can't think of an example in French, because in French everything has a gender. It would be like saying "C'est sympa, mon pote" but without a gender. 2 Link to comment Share on other sites More sharing options...

As you say, in french all has a gender. That's our latin side. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Guns Posted January 12, 2021 Author Share Posted January 12, 2021 Can i get your opinion on this one ? @Troodon Link to comment Share on other sites More sharing options...
Troodon Posted January 12, 2021 Share Posted January 12, 2021 I would lean against this being an Ankylosaurid osteoderm possibly more toward Ceratopsian. I looked at about a couple of dozen osteoderms in my collection and although they had holes none matched yours. They look more like foramen you see in Ceratopsian bones. 1 Link to comment Share on other sites More sharing options...

Troodon Posted January 12, 2021 Share Posted January 12, 2021 You really need to get more complete osteoderms to be sure. Partial bones can be difficult. Veining is a key feature of frills. They also are flatish and fat. 2 Link to comment Share on other sites More sharing options...

Dracarys Posted January 12, 2021 Share Posted January 12, 2021 Agree with Frank. This looks more ceratopsian. Perhaps a frill piece? Here’s a picture of my ankylosaur osteoderm which shows the veining. It is possible that bc yours is so weathered much of these defining characteristics are missing. Yours does show some of these features if you “squint”. Link to comment Share on other sites More sharing options...

Hi! thank you a lot for the help and for the compare photo! look like anky osteoderm also have some veining and a lot of hole while ceratop frill have veining as a key feature and have a a few hole but not as much as Anky osteoderm... & Link to comment Share on other sites More sharing options...
