Help Identify Jawbone


Hello_There

Recommended Posts

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.

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.

I tried to think of what teeth might fit this jaw section and came up with this link..

You are going to need a much more specific locality

Very sorry for the confusion.  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.

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

Yep. Closest town/River/peak is helpful.

 

I too tend to keep my non public sites vague- I fear poaching and vandalism.

Closest town or County are precise enough to help and vague enough to protect your site from impudent gluttons.
