PaleoNoel Posted July 31, 2018 Share Posted July 31, 2018 Hi all! I returned from my trip out west a few days ago and wanted to have some fossils identified before I do my big recap of my experience and my photos from the field. Here are some specimens I found of which I'm not certain of their identity. (This will not be my last post of this type from this trip). 1. Small theropod tooth (Richardoestesia sp.?, Acheroraptor temertyorum?). (There appear to be serrations on the front of the tooth but the majority of them seem to have worn off or did not extend further than midway through the tooth). (Near Newcastle, WY, Lance Fm.). 2. Turtle/Croc toe bone? (Near Newcastle, WY, Lance Fm.). 3. Larvae? (Douglas Pass, Green River Fm.). Link to comment Share on other sites More sharing options...
GeschWhat Posted July 31, 2018 Share Posted July 31, 2018 That larvae? is really interesting. Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Troodon Posted July 31, 2018 Share Posted July 31, 2018 1) Hard to call but would lean toward Acheroraptor. Denticles not right for Richardoestesia or Nanotyrannus 2) Think it's turtle 3) Not old enough no clue Link to comment Share on other sites More sharing options...
ynot Posted July 31, 2018 Share Posted July 31, 2018 Interesting. Maybe a pupae. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Also the serrations didn't seem large enough for Pectinodon, I just wanted a confirmation to my thought process as it seemed pretty limited as to what it could be.

Fossildude19 Posted July 31, 2018 Share Posted July 31, 2018 The insect looks like some sort of larval Diptera.

R. gilmorei can be slightly recurved. R. isosceles is straight. I have some Tyrannosaurid teeth that size and smaller. Link to comment Share on other sites More sharing options...

Yeah I'm just generalizing the smaller theropod teeth, seeing that my tooth didn't share the the key traits of the non-dromaeosaurids in the area. P.S. You have tyrannosaur teeth under 6 mm? That's quite impressive. I'm pretty sure my smallest tyrannosaur tooth is just the tip of a Gorgosaurus/Daspletosaurus (Judith R. Formation) and that was probably larger than this tooth from Wyoming. Thanks for sharing your knowledge. Link to comment Share on other sites More sharing options...
Troodon Posted July 31, 2018 Share Posted July 31, 2018 My smallest Nanotyrannus teeth are 2.8 and 3.8 mm and my smallest Trex teeth are 4 and 4.4 mm The smaller teeth are later in the attached topic Link to comment Share on other sites More sharing options...
jpc Posted July 31, 2018 Share Posted July 31, 2018 I am leaning towards Acheroraptor on the tooth, and croc on the toe bone. Larva... yes, not larvae (plural). Need an insect expert and good views of the head and tail ends to ID it. Link to comment Share on other sites More sharing options...
Carl Posted July 31, 2018 Share Posted July 31, 2018 I have found larvae like that at Douglas Pass and I was told they are botfly larvae. Link to comment Share on other sites More sharing options...

Thanks, after looking at some pictures online it looks like that's probably what it's from. Link to comment Share on other sites More sharing options...
