Jurassicz1 Posted April 4, 2022 Share Posted April 4, 2022 I got this baculite in a fossil show. From the Pierre shale of South Dakota. He gave me a handwritten label that I can't tell what it says 100% Regards - Adriano 1 Link to post Share on other sites

FossilDAWG Posted April 4, 2022 Share Posted April 4, 2022 Here's a link that might be useful: Baculites scotti It's tough to ID many of the Baculites species, especially from a single fragmentary specimen. However B. scotti is almost completely smooth, it has a very small angle of taper, and the suture line is consistent with your specimen, so the ID seems reasonable to me.

What is the age of the Pierre Shale? I know it's Upper Cretaceous, but what stage, Campanian? Edited April 4, 2022 by Jurassicz1 Link to post Share on other sites
FossilDAWG Posted April 4, 2022 Share Posted April 4, 2022 Baculites species define a series of biotic zones within the Pierre Shale. Most of the Pierre Shale is Campanian, but it does range up into the lower Mastrichtian. However Baculites scotti is middle Campanian. Don 2 Link to post Share on other sites
