3 years, 3 months ago3 years, 3 months agoGreetings @a-trilobite and @david-todd ! Regarding this specimen, I do not believe this is a rib cage of any sort. it could be a result of erosion as you mention or at best some kind of burrows. That’s the best I can do for now. If there was someone on here who specialized in ichnofossils they could help determine an ID.
