gturner333 Posted September 18, 2018 Share Posted September 18, 2018 I found these two going through some Lance formation (late cretaceous) matrix from Wyoming. The first (2 views) is a mammal tooth 1.9mm long and I am just showing it because I am proud of it. The 2nd, 4 views, looks like a mammal molar on one side (the side with the wavy lines similar to a rodent molar), but not necessarily on the other sides. I arbitrarily named two sides top and bottom but they may not be that. Any idea what the 2nd fossil is? The hash marks are 1mm. Thanks. Link to comment Share on other sites More sharing options...

jpc Posted September 20, 2018 Share Posted September 20, 2018 the second one looks like a partial molar of a multituberculate called Meniscoessus. it is the biggest Lancian multi and has crescent shaped cusps. The first one is definitely a partial upper molar of either a eutherian or a marsupial. I think that is what I am seeing. (No rodents back then.) Good finds.

gturner333 Posted September 20, 2018 Author Share Posted September 20, 2018 Thanks. I thought it looked like a molar but was thrown off by the crescent shapes being on the side. Link to comment Share on other sites More sharing options...
