As I continue to sift through my bag of micro matrix from the Aguja Formation, I came across this interesting little mammal tooth. It looks to me like an incisor but I suppose it could also be a canine. I am completely unfamiliar with Mesozoic mammals and I’m not even sure how far down this tooth is distinguishable, but I thought I’d post it anyway. Super excited as this is my first Mesozoic mammal tooth.

 

Size: ~0.5cm

Thanks for any information/resources you can point me to. As always, I deeply appreciate everyone taking the time to help.

Definitely looks like an incisor of a multituberculate.  Here is one to consider.

C&B are lowers you can compare against.  The image is one from the Hell Creek but that genus is also is also known in the Aguja as M. sp.
