DenverEdge Posted October 15, 2021 Share Posted October 15, 2021 I posted in the fossil prep a few days ago about some Judith River matrix I got with teeth. Well now that I practiced on a damaged tooth shard I decided to start on this piece which seems to have two teeth laying on top of each other. I was hoping to get some help on what species these could be. I believe there is an ankylosaur tooth in good condition under the tooth that is more exposed. The small one is about a quarter inch and the larger underneath about 0.6 inches. this material is new to me and I have more matrix with different teeth so any other input is also helpful. 1 Link to comment Share on other sites More sharing options...
Agent_Zigzag Posted October 15, 2021 Share Posted October 15, 2021 Greetings! I think it's really hard to tell what kind of teeth they are based on photoes......My suggestion would be keep cleaning them until we can see some labial (lip-side) or lingual (tongue-side) details for more clues.

DenverEdge Posted October 15, 2021 Author Share Posted October 15, 2021 I was just taking pictures after a clean up actually. I’ll still be working on it while waiting for replies. Im trying to keep both teeth together if at all possible. Link to comment Share on other sites More sharing options...

After seeing the cleaned up pictures if it is still hard to I.d could I focus on the lip side or do I need more of the tongue side exposed?

If it's herbivore animals (which appears to be), the focus should be put on the lip side. That's all I can say...... Link to comment Share on other sites More sharing options...

That's all I can say...... Alright got some more of that side exposed on the larger one. I got all I could get off without taking it off the piece of wood? that it’s sitting on. It is not smooth on the lip side it has a texture that extends to the sides on the top where the angle changes. The tooth is roughly shaped like a diamond. It does strongly resemble larger ankylosaur teeth I have seen to me but I’m still new to this. Link to comment Share on other sites More sharing options...
DenverEdge Posted October 15, 2021 Author Share Posted October 15, 2021 Well the top tooth came off. Hopefully this helps. It still fits nicely where it was originally. Link to comment Share on other sites More sharing options...
Norki Posted October 15, 2021 Share Posted October 15, 2021 I think the larger piece might actually be a tumbled bit of bone. Hard to say for sure until more is uncovered. 1 Link to comment Share on other sites More sharing options...

Hard to say for sure until more is uncovered. It has a uniform wrinkled texture almost shaped like the seed pods in a pine cone that I’m having a hard time getting it to show good in the pictures. I don’t know if that makes a difference but that’s why I didn’t think it was a little bone chunk. any idea if the smaller piece is hadrosaur, or ankylosaur? Looks too thin for the ceratopsian teeth I have seen. Edited October 15, 2021 by DenverEdge Link to comment Share on other sites More sharing options...

Looks too thin for the ceratopsian teeth I have seen. I'm not sure about the smaller one. Looks a bit like the crown of a very worn-down ankylosaur tooth, if only because it seems to have that characteristic concave shape to it. Link to comment Share on other sites More sharing options...
Agent_Zigzag Posted October 15, 2021 Share Posted October 15, 2021 The smaller one might be a small cobblestone......More cleaning on the larger one gives me this sense, too...... I am not even sure whether they are fossils or not now. Link to comment Share on other sites More sharing options...

I am not even sure whether they are fossils or not now. Interesting the small one looks very similar in color and hardness general feel to crowns of stuff I know is teeth from Judith river. The larger one looks like that but with worn enamel. If that’s the case at least I got other pieces of matrix that for sure have teeth in them.

DenverEdge Posted October 15, 2021 Author Share Posted October 15, 2021 Here’s a one inch rooted croc tooth I got with the same batch of matrix to make sure this thread actually has at least one fossil in it. Link to comment Share on other sites More sharing options...

Yeah, at least it's not in vain......If there are worn enamel preserved, I would say the possibility of Hadrosaurus is higher Link to comment Share on other sites More sharing options...
Troodon Posted October 15, 2021 Share Posted October 15, 2021 I agree with the others don't see any teeth in your matrix other than the Croc tooth in the last photo Link to comment Share on other sites More sharing options...

Wonder what I’m doing wrong only herbivore tooth I had prior to this was a trike tooth. These looked like what I see people sell as spitters and had the right color.

DenverEdge Posted October 15, 2021 Author Share Posted October 15, 2021 Also I cannot find any good resources on Judith river/ two medicine teeth unless it’s a carnivore so id anyone can help me there I would appreciate it a lot. Link to comment Share on other sites More sharing options...
DenverEdge Posted October 15, 2021 Author Share Posted October 15, 2021 This is a herbivore too the right? Nodosaur or ankylosaur? Root area on bottom right? Link to comment Share on other sites More sharing options...
TyBoy Posted October 15, 2021 Share Posted October 15, 2021 Might be Ceratopsian need to see other views. Family level Identification of herbivores teeth is pretty similar to those in the Hell Creek. More difficult to get to a genus level because they are pretty diverse fauna Link to comment Share on other sites More sharing options...

Not much is out there but like TyBoy said. identification is mostly possible to a family level and I've put together some topics to help ID some families of herbivore teeth for the Hell Creek /Lance Formations but can be equally used for JRF and TMF material. The diversity makes it very difficult to get to a genus level on some teeth but Link to comment Share on other sites More sharing options...

I agree with TyBoy look more ceratopsian but like to see a top of the tooth. It may require a little more matrix to be removed. Link to comment Share on other sites More sharing options...

I’m only worried about getting an id to a family level. I’ll get that one more exposed or even removed. And the other ones you guys say are pebbles I’ll try my best to get better pictures to be sure I’ll probably remove the larger one too. Link to comment Share on other sites More sharing options...

DenverEdge Posted October 16, 2021 Author Share Posted October 16, 2021 (edited) Another of the “dimpled” area. I assume if it was a tooth it would be the top. Just wanted to get some better pictures before I condemned this piece as a pebble. Also got a picture of the side to show you guys how thin it is and it’s not rounded.

Norki Posted October 16, 2021 Share Posted October 16, 2021 (edited) I think it might just be a phosphate pebble or something. Oh well - at least you know that there will still probably be more teeth to find in those blocks! Edited October 16, 2021 by Norki 1 Link to comment Share on other sites More sharing options...
