My Jurassic Park - Ornithomimids from the Hell Creek/Lance Formations

[Troodon]

Thanks for the additional photos.  Most of the diagnostic features on claws are found on the proximal end.  The distal ends can be very similar between theropods so anything is a guess.   I tried to match your specimen to one in my collection and found this juvenile Anzu wyliei foot claw as the closest match.

Thank you Troodon, i expect that is as near as I'm going to get, i do understand the complexity of identifying isolated teeth and claws and really do appreciate you time and value your opinion, again thank you
