Fossils are the remains of past life. Groups of fossils, called fossil assemblages, can often be used to determine the age of the rock in which the fossils are found. Objectives • To identify several kinds of fossils • To compare the ages of the fossils • To identify the geologic age of the rock containing the fossils Procedure 1.

However, fossil bivalve shells may reveal transportation after death through the separation of the valves. The valves of dead Mytilacea become separated almost immediately because there are no interlocking devices capable of holding the valves in position after decomposition of the ligament.This is why most fossil bivalves are found open or in two pieces. The two shells are symmetrical with respect to each other. In other words, the top shell is a mirror image of the bottom shell. This is important to note, since bivalves and brachiopods look very similar. The difference is found in their respective symmetries.

Morphology The pelecypods are a type of mollusk that has two shells, hence the common name of bivalves. The shells are hinged together by a ligament that continually forces the shells open. Only special muscles, called adductor muscles, can close the shells together. Upon death, the shell springs open since the adductor muscle fails to work.
