Hello_There Posted December 21, 2020 Share Posted December 21, 2020 (edited) Here is what I believe to be a portion of a dinosaur jawbone found in an Upper Cretaceous portion of the Morrison Formation of N. America (sorry if that area is a bit vague). I have other fossilized bits found with it I will be adding to this post soon. Thanks for your ideas on this one.

LordTrilobite Posted December 21, 2020 Share Posted December 21, 2020 Morrison formation is Late Jurassic, not Late Cretaceous. So that's a problem. But it's definitely some type of jaw piece. It reminds me a bit of a ceratopsian jaw. But that would mean it's not from Morrison formation. Link to post Share on other sites
TyBoy Posted December 21, 2020 Share Posted December 21, 2020 You are going to need a much more specific locality Link to post Share on other sites

I tried to think of what teeth might fit this jaw section and came up with this link.. https://assets2.fossilera.com/pages/dinosaur-teeth Thanks 1 Link to post Share on other sites

I was thinking location and not actual age of the formation. For the location, let's try "Colorado Plateau". The specific area the fossil was found is beyond a doubt Upper Cretaceous.

TyBoy Posted December 21, 2020 Share Posted December 21, 2020 Well yesterday we saw a bone from the Colorado plateau and it turned out to be whale. Sorry not much to go on not sure show much late cret exposures are around there are a few. Too general. Proper identification of dinosaurs is all about provenance Link to post Share on other sites

Closest town or County are precise enough to help and vague enough to protect your site from impudent gluttons. 2 Link to post Share on other sites
