Bivalves vs. brachiopods. Bivalves and brachiopods are both types of "sea shells." both have shells composed of two valves, but the organisms inside the shells are quite different. Typically, the two valves of a bivalve are mirror images of each other (termed equivalved). Their valves are symmetrical along a plane through the hinge.Donald L. Frizzell.

> Fossils can be coiled and extended about an axis, giving them a cone-shape. These types of fossils have a distinctive shape, but lack symmetry. Other shapes > There are a variety of other distinctive fossil shapes that have no symmetry. For example, a single bivalved pelecypod shell is recognizable as a "clam shell", but lacks any symmetry.Even after decades of assiduous, dedicated scientific examination, vertebrate animal specimens remain the only diagnostic types of fossil specimens yet recovered in abundance from the Sharktooth Hill bone bed (a few internal casts of gastropod and pelecypod shells have also been reported from the bone bed, in addition to occasional coprolites ...Inoceramus, genus of extinct pelecypods (clams) found as fossils in Jurassic to Cretaceous rocks (laid down between 199.6 million and 65.5 million years ago).

It discusses the correlation, distribution, and environmental interpretation of the Helderberg formations and their fossils, and provides a comprehensive bibliography of the …The valves are the parts usually found as fossils, but decay of the elastic hinge tissue that joins them means that they are rarely preserved together. Anatomy ...However, fossil bivalve shells may reveal transportation after death through the separation of the valves.

The fossil record of mollusks is relatively complete, and they are well represented in most fossil-bearing marine strata.Although bivalves are much more abundant than brachiopods today, in the Paleozoic Era, when most of Kentucky’s bedrock formed, brachiopods were much more abundant than bivalves.
