Hi, @jon-moore – is Toxasteridae the family or is there some disagreement about that? I know some of the higher taxonomy can be a bit complicated. Here is an occurrence I found from iDigBio: https://www.idigbio.org/portal/records/1f57e28a-dda9-444e-b368-e8a22b19f74c
I also found really nice images on the Echinoid Directory: https://www.nhm.ac.uk/our-science/data/echinoid-directory/taxa/specimen.jsp?id=7162

Do you have a photo of the other side of the specimen as well?
Talk to you soon,

Hi Jen, I’m not sure about the higher taxonomy. Toxasteridae does seem to be the commonly used family for this genus, but at least one document said that family is paraphyletic. I didn’t photograph the oral side, because it was not completely cleaned of matrix, but I can try to clean the specimen and then take a pic.
Ah, yes, the common issue in fossils – figuring out what is paraphyletic or not. A never ending problem across all of life!
