Dino9876 Posted March 13, 2020 Share Posted March 13, 2020 Hello, I've put teeth here for Id a couple of times and always received a satisfactory answer. I hope you can help me this time too. It is about this Ceratopsidae tooth from the Niobrara Formationn (Wyoming). Unfortunately no fossils of this group are known from this formation and I therefore wanted to ask you if you have any idea what species of dinosaurs the tooth could belong to. The tooth is 1,5cm in size. I hope if you can help me with this! Best regards from Germany! 1 My collection of Uncommon extant shark teeth - Here My collection of interesting rare shark jaws - Here Link to comment Share on other sites More sharing options...
Troodon Posted March 13, 2020 Share Posted March 13, 2020 Do you have a more specific location where this tooth came from? Additional photos. 1 Link to comment Share on other sites More sharing options...
jpc Posted March 13, 2020 Share Posted March 13, 2020 This is certainly a ceratopsian tooth.. .quite worn. If it is from Wyoming, it probably comes from the Lance Formation. Most of the Lance Formation outcrops here are in Niobrara County. Do you see where I am going? I would feel comfortable calling it Ceratopsian form the Lance Fm in Niobrara County, WY. I think it got just slightly mislabeled between the find and the final sale. 5 Link to comment Share on other sites More sharing options...

But I know the seller very well and he said that the tooth definitely comes from the extreme southeast of Wyoming, where the Niobrara Formation is.

Troodon Posted March 13, 2020 Share Posted March 13, 2020 Lusk is Niobrara County. Its definitely Lance Formation. Agree Ceratopsian tooth, Triceratops or Torosaurus sp. 6 Link to comment Share on other sites More sharing options...

jpc Posted March 13, 2020 Share Posted March 13, 2020 This makes me wonder about the dealer... a) Niobrara County, not Fm b)Lance Fm not Niobrara Fm c) There is no Niobrara Fm in extreme southeastern WY d) there is no Lance Fm south of Lusk until you get to the next county. e) There is tons of lance Fm north of Lusk, which is most certainly where this came from. f) anyone who calls Lusk a city has never been there (I love Lusk) I would be wary of this dealer's knowledge of details. Not meaning to insult your forend, but if I was talking to him/her face to face, yes, I would call them on this. 2 Link to comment Share on other sites More sharing options...

I wanted to find out which formation the tooth comes from and came across the Niobrara formation, which according to some maps on Google was right there. That is why the question arose for me. And I'm from Germany, so I don't know anything special of Lusk.
