Authigenic Mineralisation - A very special form of cast and mold formation where a nodule is formed around the fossil by minerals such as siderite. Clams are surprisingly agile creatures, able to burrow in the sand in their search for food and shelter. The muscle that connects the clam’s two halves relaxes at death. The dead clam opens up, and scavengers eat the insides.

These extinct clams lived in groups on the sea floor of the ...While recognizable as mollusks, many of these fossils belong either to sister groups or to stem groups of living classes.
