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.
How Big Are Brachiopods? The largest fossil Brachiopod is 7.9 inches (200 mm). Most are 2-4 inches (3-8 cm). Living Brachiopods also fall into this range. Where Do Brachiopods Live? Brachiopods alive today live in cold, marine environments like polar seas and the continental shelf and continental slope.
Jan 5, 2023 · Brachiopod profiles are commonly described with a terminology based on the curvature of the valves.

Brachiopods are marine animals that secrete a shell consisting of two parts called valves. Their fossils are common in the Pennsylvanian and Permian limestones of eastern Kansas. Brachiopods have an extensive fossil record, first appearing in rocks dating back to the early part of the Cambrian Period, about 541 million years ago.
Brachiopods are the state fossil of the U.S. state of Kentucky. [6]The fossil record shows that nearly all the crinoid species died out at this time. The one or two surviving lineages eventually gave rise to the crinoids populating the oceans today. Based on the fossil record of crinoids, especially the details of the plates that made up the arms and calyx, experts have identified hundreds of different crinoid species.List of brachiopod genera.

One crucial fossil linking the tommotiids with brachiopods is Micrina. Analysis on the microscopic inner structure of the phosphatic shell has shown similarities to the organophosphatic brachiopods, one of them being tubes - that must have housed setae in life - perforating the shell layers.
This is a medium sized brachiopod fossil. It has an easily identifiable shape, looking like a half-circle. The pedical valve is very convex, while the brachial valve is concave. It also has strong radial striations running the length of both shells. There is a very similar looking brachiopod called Megastrophia concava.
