No other organisms typify the Age of Invertebrates more than brachiopods. They are the most abundant Paleozic fossils, except for maybe trilobites. Because of this, paleontologists use them to date rocks and other fossils. Countless billions accumulated on the ocean floor in over 30,000 forms.

Brachiopods , phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. … See moreThis animal was a filter feeder, using its lophophore to extract organic matter from passing seawater.

A Modern Day Brachiopod. Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.Bivalve. Bivalves include modern clams, mussels, scallops and other groups. They have a long fossil record, from the early Cambrian Period to the present.
