Braciopod
Brachiopod diversity (class, order, and genus) recorded in the Devonian units from the Amazonas Basin. In the Early Devonian, there was a clear differentiation between equatorial and polar temperatures, which led to a notable increase in the provinciality of shallow marine benthic faunas (Boucot and Blodgett, 2001; Penn-Clarke and Harper, 2020).Kentucky designated brachiopod as the official state fossil in 1986. All State Dinosaurs & Fossils Fossilized brachipods were once the shells of marine animals of the Paleozoic era (the Paleozoic era was from about 542 to 251 million years ago). Because the state was covered by ocean water in prehistoric times, hundreds of different types of brachiopods …Depsite their relative obscurity today, brachiopods have a long and rich paleontological history. During the Paleozoic era, they were extremely abundant. They diversified into a number of different morphologies and even participated in the build-up of ancient reefs.

Jan 5, 2023 · Brachiopod profiles are commonly described with a terminology based on the curvature of the valves.

Brachiopods have two shells, called valves, which house the creature inside. Through a hole in one of the valves, known as the pedicle foramen, extends a fleshy ligament called the pedicle.
