Carboniferous320 Posted October 11, 2019 Posted October 11, 2019 Hello, I saw this online. Just curious if it actually is what the label states: Oreodont Braincast / Badlands of South Dakota / Oligocene Period. Thank you for any and all help.

caldigger Posted October 12, 2019 Posted October 12, 2019 It looks like the one I have. Your label is probably correct. 1

However, I have seen the texture shown in the below picture of this posted specimen before. I was finding a few very hard specimens on my sons' ranch that I thought might be coprolites. So I sent them along with actual coprolites to the NMMNH&S to be evaluated. These specimens have the red Xs in the below picture. Dr. Lucas from the NMMNH&S told me that they were concretions. So I'm very suspicious of the posted specimen although it does show a different texture on part of it. If they were brain casts, then Dr. Lucas disposed of the three shown below.

caldigger Posted October 12, 2019 Posted October 12, 2019 I'll post a pic of mine when I get back in town on Monday.
Randyw Posted October 12, 2019 Posted October 12, 2019 Two of my Oreodont skulls I recently prepped had either part or all of the brain cast exposed. Both Tina and Quasimodo showed it. unfortunately all I have is the sellers picture showing the top of Tina’s braincase I had already mounted the skull pieces back in place before I took my picture.i could probably pop those pieces off to take a better picture if it would help. But here’s my picture of Quasimodo and the sellers picture of Tina’s. Your pictures do have some elements that are similar to theirs.

Carboniferous320 Posted October 13, 2019 Author Posted October 13, 2019 Thank you so much everyone for the helpful input. This information has greatly increased my confidence in the identification of this piece. Thanks again for taking the time to help!!
jpc Posted October 13, 2019 Posted October 13, 2019 Hmmmm.... upon looking again... To me, a brain cast has no bone on it. This one has a skin of bone on it, so I would stop shy of calling it a brain cast. If anything I might call it a possible brain cast with skull bits. To be a cast, technically it would need to show the shape of the inside of the skull.
