Ceratopsian Frill? Just rock?
Dino Dad 81 posted a topic in Fossil IDHi all, I’ve been putting in time to working the clay matrix off of this bone/rock from the Lance formation in Weston, Wyoming. In the process, I’ve gone back and forth on whether it’s just a rock and no fossil to now thinking it may be a sizable chunk of ceratopsian frill. Any help would be much appreciated as I hate putting in the time and having to wonder if it’s even a fossil at all. If it is a fossil, how agressive do you think I should be about working matrix off vs leaving it as-is? Thanks!!

Lance Fm. Sacrum?
PaleoNoel posted a topic in Fossil IDHere's an interesting looking partial bone I found in the Lance fm. of Wyoming back in 2018 with PaleoProspectors. The guide I was with thought it could've been from the hip region of a reptile, possibly a champsosaur. After a few years of gradually improving my identification ability I now think it's a partial sacrum, but I am not sure. I want to know what my fellow forum members have to say about it.
