Bill Heimbrock commented on Matt Croxton‘s Fossil #006436 5 years, 7 months ago
5 years, 7 months ago5 years, 7 months agoAs always, knowing where it was found is very helpful for correct identification. If this was found in the Cincinnatian Richmondian Stage, it looks to me like an encrusting coral called Protaraea richmondensis. For more photos of this particular species, see http://www.drydredgers.org/thumb_by_coral.htm#Protaraea
Hope this helps.

Thanks, Bill! I always manage to forget about Protaraea!
