John Christian commented on Lisa Lundgren‘s Fossil #013313 7 years, 6 months ago
7 years, 6 months ago7 years, 6 months agoI don’t see very many, if any, spines. If spineless, this could be Lophophyllidium plummeri. See “The Color Guide To Pennsylvanian Fossils of North Texas” by McKinzie for a description and photos of both species.
Good point! I was looking at a black and white copy of the McKenzie fossil guide that was handed out at the field trip. Sometimes, things get a little fuzzy. Could the protrusion on the top be a bryozoan? I can take another picture and add it tomorrow.
I’d go with Lophophyllidium plummeri since I don’t see any spines. I can’t tell if there are any bryozoan on top.
