Brachiopods have a feeding structure called a lophophore, an organ with tentacles and finer hair-like cilia that is used to filter small food particles from seawater. The name “brachiopod” is from Latin brachium for “arm” and ancient Greek pod for “foot.”. The name was inspired by the two “arm” branches of the lophophore and its ... The brachiopods were a dominant group during the Paleozoic era (542-251 mya), but are less common today. Modern brachiopods range in shell size from less than five mm (1/4 of an inch) to just over eight cm (three inches). Fossil brachiopods generally fall within this size range, but some adult species have a shell of less than one millimeter ...

Brachiopods are (perhaps all too) familiar to any geology student who has taken an invertebrate paleontology course; they may well be less familiar to biology students. Even though brachiopods are among the most significant components of the marine fossil record by virtue of their considerable diversity, abundance, and long evolutionary history, fewer than 500 species are extant. Reconciling ...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.
Brachiopods and Bivalves A theory on the morphology ERTH2312A Paleontology Presented to Professor T. Patterson Joachim de Fourestier Student Number: 101022736 27/03/2017 Brachiopods and Bivalves are superficially similar, but are rather distantly related. Both are twin-valved and are filter-feeders. That said, what caused these morphologicalThe brachiopods experienced five main extinction events followed by recoveries and radiations of varying magnitudes (Fig. 10). Following initial radiations during the Cambrian, brachiopods diversified, extravagantly, during the Ordovician ( Harper et al., 2017 ); this radiation was temporarily halted at the end of the period.
