duck-billed dinosaur tooth

[Compy]

My last acquisition was this worn teeth of what the seller used to describe as duck-bill dinosaur from the Hell Creek Formation in Montana.

In my opinion it does look like some hadrosaurid teeth but I cannot assign it to a single species...

Correct, it is a worn Hadrosaurid tooth.  I would label it as Hadrosauridae indet.

 

Believe Edmontosaurus is only known Hadrosauridae currently described from HCF but I think it is reasonable to expect that others may be present.

Thank you very much as always for your help!

I admire your broad knowledge! I think I will need ages to know what to look for and who lived when in which fauna...

Learned something new (again). I wouldn't have even recognized that as a tooth.
