This is a wonderful specimen of LOXONEMA. It is a “Steinkern” that still has part of the external shell attached to the internal mold. Only the bottom portion is the mold the rest is fossilized shell material. The LOXONEMA is 2.21 inches long and .77 inches wide at its widest point.
Related to modern day snails, there are species alive today that resemble their prehistoric predecessors.
It comes complete with this handsome black and glass collectors box.
