Pelecypod
Lab 7: Geologic Time 5 (Figures 7-2 and 7-3). For example, a marine animal called a trilobite lived only during the Paleozoic Era. Rocks containing trilobite fossils can be inferred to have been deposited during The pelecypod Donax gouldi is the most abundant, and in places the rock is a Donax coquina. The formation as a whole is an open sandy beach deposit. The presence of Rissoina nereina and the echinoid Mellita longifissa indicates that sea-water temperatures were warmer than now.
