val horn Posted July 25, 2020 Share Posted July 25, 2020 I was given this very small piece of ?mandibular bone. Any help would be appreciated in id. it is approximately 12-14 mm in length, 4 mm in height and maybe 2 mm on the dental surface from the hells creek formation in montana.

jpc Posted July 25, 2020 Share Posted July 25, 2020 The photos are a bit fuzzy, but it looks crocodiish. Link to comment Share on other sites More sharing options...
PaleoNoel Posted July 26, 2020 Share Posted July 26, 2020 Looks similar to bowfin jaw sections which I've found and seen from the Hell Creek and Lance fms. Link to comment Share on other sites More sharing options...
PaleoNoel Posted July 26, 2020 Share Posted July 26, 2020 Croc jaw sections generally have more vascular canals. From Wyoming: From South Dakota: Link to comment Share on other sites More sharing options...
Troodon Posted July 26, 2020 Share Posted July 26, 2020 Can you take brighter and sharper photos of your jaw. Like to see how deep the tooth sockets are. Croc would be deep and not typical of fish. Could be croc. Link to comment Share on other sites More sharing options...
