Clam fossils
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. But often the fossils retain both shell halves, tightly closed—all “clammed” up (Figure 1).
