Wowbnjijdat Posted March 21, 2017 Share Posted March 21, 2017 Hi guys, On a auction website I bought a collection of small Dinosaur/ Mammal fossils from the Lance Formation in Wyoming. First photo: Have you any idea which teeth belong to what dinosaur or Mammal? And is the central left piece an crocodile scute? Second and third photo : Is it true, this could be an Ankylosaur scute? thank you very much! Link to comment Share on other sites More sharing options...
Wowbnjijdat Posted March 21, 2017 Author Share Posted March 21, 2017 A better photo of the teeth Link to comment Share on other sites More sharing options...
Troodon Posted March 21, 2017 Share Posted March 21, 2017 Hard to see the items on the first photo. Can you take a closer picture of the individual specimens. I don't see a anky scute. The surface texture on your top photo is too rough for one. Can you post a picture of the side. Edit: that's good Link to comment Share on other sites More sharing options...
Bguild Posted March 21, 2017 Share Posted March 21, 2017 Some of the tooth fragments look like they could be from Edmontosaurus and Triceratops. 1 Link to comment Share on other sites More sharing options...
Troodon Posted March 21, 2017 Share Posted March 21, 2017 Very difficult to determine what you have. The ones circled in white might be ceratopsian spitter tooth fragments. The red one might be a gar fish scale Link to comment Share on other sites More sharing options...
Wowbnjijdat Posted March 21, 2017 Author Share Posted March 21, 2017 some more pictures of the possible ankylosaur scute: Link to comment Share on other sites More sharing options...
Wowbnjijdat Posted March 21, 2017 Author Share Posted March 21, 2017 Possible croc scute? Link to comment Share on other sites More sharing options...
Troodon Posted March 21, 2017 Share Posted March 21, 2017 I'm still leaning away from that bone being a scute, the surface texture just does not look right. Your other peice does not look like a crocodile scute. Looks too thin and the cavities are not uniform or defined. Example. 2 Link to comment Share on other sites More sharing options...
Wowbnjijdat Posted March 21, 2017 Author Share Posted March 21, 2017 Hmm thats a shame, it is just a bone then (the 'ankylosaur scute')? I bought from the same reseller also an Ankylosaur tooth (see photo) but is it? I have a croc scute from the Kem Kem, so in comparison they have some similarities, what do you think it is?

Troodon Posted March 21, 2017 Share Posted March 21, 2017 Sellers put a generic name on these type of teeth and call them ankylosaur. It's actually a Nodosauridae tooth which is in the family of ankylosaurian dinosaurs. Depending on where it comes from could be an Edmontonia sp. I cannot say what your other fragment is. Here is a topic I put together on this family of teeth. 4 Link to comment Share on other sites More sharing options...
Wowbnjijdat Posted March 21, 2017 Author Share Posted March 21, 2017 Interesting! I didn't know that.. The tooth is from the Judith river formation, so Edmontonia is probably right? Link to comment Share on other sites More sharing options...
Troodon Posted March 21, 2017 Share Posted March 21, 2017 I not aware what Nodosaurid has been described from the Judith River Fm, if any. However if you compare that fauna to those equivalent in age, Alberta's Dinosaur Park Fm, they have multiple species described. So since these faunas appear to be more diverse I would guess that more than one Nodosaurid is present in the Judith of Montana. The most accurate ID: Nodosaurid indet. If you feel compelled to put a species name Edmontonia is okay. Link to comment Share on other sites More sharing options...
