fossil35 Posted May 23 Share Posted May 23 I was wondering if any could help with the ID of 3 pieces from Wyoming (Lance creek Formation is what was told). They are very small and broken but maybe someone know of an ID or maybe even if its dinosaur or something different? #1 (first) #2 (closer) #3 (other side) #4 (different view) Second piece #5 (sorry piece was very hard to hold for photos) #6 (other angle) #7 (top) Third piece #8 (wasn't sure what was) #9 #10 #11 1 2 Link to comment Share on other sites More sharing options...

Brevicollis Posted May 23 Share Posted May 23 1 appears to be a partial Troodontid tooth to my eyes, maybe @ThePhysicist can help here. I have absolutely no idea, what the other pieces could be. Are good signatures really that important ? Link to comment Share on other sites More sharing options...
Coco Posted May 23 Share Posted May 23 Hi, I am not an expert on dinosaurs, but by dint of seeing some here, this little bit of tooth also reminds me of a troodontidae by its curvature and the size of the "sawteeth". For the others, I don’t know.

jpc Posted May 23 Share Posted May 23 yes, #1 is the tip of a Pectinodon tooth. #2 (large, nay, huge cusps), is also the tip of a tooth, either a croc or maybe a Ricardoestesia. The third one may be a fish jaw piece, but tough to tell. 1 Link to comment Share on other sites More sharing options...
fossil35 Posted May 23 Author Share Posted May 23 Thank you for the help everyone. Glad I checked the little piece of sandstone (find every little bit can find). Was hoping for little micros but broken bits turns out interesting. Link to comment Share on other sites More sharing options...
jpc Posted May 24 Share Posted May 24 those Lance sandstones can have a lot of stuff in them. Link to comment Share on other sites More sharing options...
fossil35 Posted May 25 Author Share Posted May 25 I was looking again though the bits of sandstone matrix and areas was cleaning, think may have found other half of #1 and sure other half #2. Found few more bits that didn't seem to go to anything and an extra tooth thinking not dinosaur, maybe fish. Not sure if I'll try to put the tooth together as they are hard to even hold, may end up glue to myself or something else (#1 seems to be missing bits in middle of two pieces). #1 (#1 with half found) #2 (closer) #3 (other side) #4 (other half from #2 from first post) #5 (other side) #6 (found few other broken bits after looking again) #7 (as well as another that thinking fish tooth) #8 (other side closer) Link to comment Share on other sites More sharing options...
ThePhysicist Posted May 25 Share Posted May 25 Nice micro finds! #1 certainly troodontid, Pectinodon #4 now can confirm it's a crocodyliform (conical, carinated). #6 are theropods, my intuition says they're likely troodontid, especially the middle one with the large posterior denticles and absent anterior ones. #7/8 amiid fish tooth, Melvius (carinated, lanceolate) 2 “The most incomprehensible thing about the world is that it is comprehensible.” - A.

fossil35 Posted May 25 Author Share Posted May 25 Thank you for the farther IDs. Found most the extra bits in the strainer, was rushing that day and forgot to check any bits that may have been stuck in strainer. Will remember check for stuck bits in strainer in the future.

fossil35 Posted June 7 Author Share Posted June 7 I had one found and was trying prep out. Wanted ask to be sure before labeling but thinking its a Troodontid, Pectinodon again. As well if anyone would know anything can do to help keep the sandstone from falling apart. Its on a very small piece that is a bit thinner. And as was trying to prep out bit starting see a few cracks so didn't want risk anymore. There was a little bone piece under was trying prep see what was but it started moving a little so stopped. #1 #2 3 Link to comment Share on other sites More sharing options...

You'll probably want some penetrating stabilizer, like paleobond PB002 if you're done prepping, or a low-strength reversible one if not. “The most incomprehensible thing about the world is that it is comprehensible.” - A.

fossil35 Posted June 7 Author Share Posted June 7 (edited) Thank you for ID. I'd like to prep bit more but with the crack at the tip and the serrated bits showing cracks afraid may mess up. All I got is pins and dental picks to prep with. I have some Starbond super fast thin stabilizing finish, think that may work? If not i will have see about trying get the other.

fossil35 Posted June 7 Author Share Posted June 7 After posting I kept thinking about it and ending up thinking, would be better if could get the serrated part a bit more prep. So I gave it a go. It wasn't to much more but with tools I have I think its the best I can get (getting the scope as close as can, couldn't even get fingers and pins under scope anymore . What ended at. 1 Link to comment Share on other sites More sharing options...
SPrice Posted June 7 Share Posted June 7 (edited) Well... THAT tooth surely piqued my curiosity! The ID, if correct, and it looks right from what I researched , may turn out to be from a species like - Pectinodon bakkeri.ys The Latin translation ( which also is always interesting to me ) comes out to read as - pecti = comb, odon = tooth. Comb tooth. Looks like it fits the bill nicely. The blue character on the right side of the human silhouette and third in line under the Torosaurus chin. Congrats on the finds!

fossil35 Posted June 7 Author Share Posted June 7 Sorry I posted wrong photo from what meant to. That was photo just before I tried to do little touch ups at the end. It wasn't much different but think turned out ok. Think got right this time, final finished photo. Link to comment Share on other sites More sharing options...
fossil35 Posted June 8 Author Share Posted June 8 Thanks for all the info everyone. I had a few more would like check with others on. And a question about one if anyone knows. #1 (I wasn't sure if this was a tooth or bone some kind) (it popped off broke like that and tried clean best could but was hard to hold to clean well) #1 (side) #1 (other side) #1(bottom) #2 (was thinking maybe some kind fish tooth) #2(closer) #2(side) #3 (had a question on this one if any knew) I was thinking these teeth where Edmontosaurus, found few broken bits of some. This one looked way different on the bottom broken part then any of the other broken ones. Was wondering if that is normal look for this one? #3(top) #3(broke bottom) 1 Link to comment Share on other sites More sharing options...
