Size 5-7 cm

found in marine deposit

Late Cretaceous

 

They appear like limestone replacing some softish fleshy animal, no crust or visible parts marked by lines as in different shelled species. They nether seem to have interior bones as the case in vertebrate. The peak-like things sticking out at the 'front' seam to appear like the beginning of longer (maybe hard) ligament-like part of the animal that might have served some function related to eating or attack. These 'front' things are always found broken at about 5 to 10 mm away from the body, they are always of 2 bigger parts one slightly bigger and partially surrounds the other and they stick our side by side on an axis perpendicular to that of the main body, and there are 4 (?) other smaller peak-like things 2 to 3 mm thick which are often broken at a shorter distance

The skin' has no marks or patterns, they all have a circular depression placed symmetrically at both sides with an inner smaller circle bulging, of-center, within each of the bigger circles.

To my un-scientific eye they look like the filling for an oyster or clam that decided, through evolution, to get rid of its shell.
