From the album: Hell Creek / Lance Formations
Cimolodon nitidus Hell Creek Fm., Meade Co., SD, USA M1 (1st upper molar) While you may have mistaken it for a rodent, Cimolodon belonged to a far more ancient and wildly successful group of mammals, the multituberculates (so named for the multiple cusps arranged in rows on their molars). It likely ate seeds and nuts which were handedly ground by its lego-shaped molars. Cimolodon had to be wary of the likes of Pectinodon or other small predatory dinosaurs in the Hell Creek ecosystem. Unlike a few other contemporaneous mammals, this cousin of ours did not survive the K-Pg extinction event and perished along with the non-avian dinosaurs.-

From the album: Hell Creek / Lance Formations
Mesodma sp. Hell Creek Fm., Garfield Co., MT, USA P4 (4th upper premolar) Mesodma was a genus of multituberculate mammal that lived in the same environment as many well-known dinosaurs. It must've been a hardy animal, given the genus survived the K-Pg extinction event.-

Hey y'all, recently got this Cretaceous mammal molar from the Lance Fm., Weston Co., WY. It's about 8 mm long. I'm thinking Didelphodon sp.? @jpc

Right now you'll be seeing a lot more posts from me as I'm making a concerted effort to get some of my fossils ID'd which I've been slacking on for a couple months (between, college, work et.). Anyway, here's a cool little tooth I found searching through some Texan Aguja formation (Late Cretaceous, Campanian) matrix I got from PaleoTex. It was found with its roots still attached but unfortunately they've since broken off, however I've kept them in the same container so I don't lose track of them when I eventually try to reattach them. I'm confident it's a mammal tooth, and I think it's from a multituberculate. I'd be interested in reading some opinions on it and if it's possible to narrow down any ID, whether that be to order, family or genus level. It's about 2.5 mm in length and 2 mm in width.

From the album: Aguja Formation
A very small ( ~ 1 mm in length) mammal/multituberculate premolar. Indeterminate species. I unfortunately broke part of the root after this picture was taken. -

Found another suspected Cretaceous mammal tooth from the Aguja Fm. I've made my way to the fine matrix. This tooth is about 1 mm in length; I have no idea how I managed to find it. I unfortunately broke part of the root putting it back in the gem case I chose to store it in (after taking the pics). @jpc, what about this one? Feeling slightly more confident...

Hey y'all, found what I think may be a Cretaceous mammal incisor. I was hoping to find some mammal teeth when I got the Aguja matrix, but since I haven't found any before, need more experienced eyes. Could very well be a piece of something else. It's about 5mm in length. Thanks!
