I bought this out of curiosity and because I think it's rather beautiful. It was sold as a bryozoan which it clearly isn't though you can see why it was. It seems to be a diploporitan echinoderm, showing internal structure of plates (humatipores) and a small area of the external layer with diplopores. The location is given as Tafilalet region, Erfoud area, Anti-Atlas Mountains. My questions are: 1) is it Devonian (as sold) or perhaps Ordovician? Both are possible for the area - I've read that Devonian diploporitans occur in Morocco. These would be sphaeronitidae - the only group to survive into the Devonian. 2) Has anyone come across anything similar from Morocco, or indeed elsewhere, and can you narrow down the ID? Back surface, showing that it consists of articulated plates (these are the same plates as the other side, it's not a compressed hollow specimen). patch of diplopores: Ramifying humatipore respiratory structures: Closeup of plates showing pustular ornament:
