Gen. et sp. indet. Posted August 11, 2011 Share Posted August 11, 2011 (edited) It is a central European glacial erratic boulder (Geschiebe) in a form of a calcitic fossil. It is somehow similar to tabulates, stromatoporoids, and rugosans found in the same sediments. I think it might be a part of one of these, or something different (rhodophyte, chaetetid, conularid) As you can see, the walls of the concave square cells are convex and sinous - but still not randomly. The other side of the rock is uninformative. The upper side of the specimen is ca. 11 mm long. Please help. Edited August 11, 2011 by Gen. et sp. indet.
