Dino Dad 81 Posted April 30, 2023 Share Posted April 30, 2023 Hi 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!! Link to comment Share on other sites More sharing options...

Dino Dad 81 Posted May 1, 2023 Author Share Posted May 1, 2023 Thanks, @Troodon. Given that, I'll give it some less cautious last effort and then, most likely, dump it. Link to comment Share on other sites More sharing options...
