Inarticulate Brachiopod Larvae Description Brachiopods are marine animals with upper and lower shells, not to be confused with bivalves which have left and right shells.

Brachiopod definition: any marine invertebrate animal of the phylum Brachiopoda , having a ciliated feeding... | Meaning, pronunciation, translations and examplesIn many ways, Brachiopods resemble Pelecypods. 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. The pedicle is used by the brachiopod to attach itself to the sea floor. Silurian is a period with the shortest duration in Phanerozoic except for the Neogene and Quaternary. It represents an important and unique interval when the biotic diversity recovered quickly after the end-Ordovician mass extinction, different paleoplates or terranes conjoined, big oceans disappeared or narrowed, climate and sea level changed …

Lingulata shells are composed of a combination of calcium phosphate, protein and chitin. This is unlike most other shelled marine animals, whose shells are made of calcium carbonate.

I did some reading and found some theories on why some think most of the abundant brachiopods died off (95% of species) while the pelecypods prospered so well. I read that pelecypods use an energetically-efficient ligament-muscle system for opening valves, and thus require less food to subsist. Brachiopod species, and genera exhibit strong depth preferences and benthic assemblage (BA) zones have long been used as depth indicators in the early Palaeozoic [26–28]. Each genus in our dataset was assigned to a range of BAs based on information in the literature, often with reference to associated fauna or lithology.Dec 22, 2007 · Guests. Posted December 22, 2007.

The lophophore is a feeding structure that consists of a ring of tentacles surrounding the mouth. These tentacles are equipped with cilia that generate water currents to bring in food particles, which the brachiopod filters and consumes.
