Summary
[edit]DescriptionTerebratalia transversa (brachiopod shell) (modern; offshore California, USA) 3.jpg |
English: Terebratalia transversa (Sowerby, 1846) - brachiopod shell from California, USA. (view of ventral valve)
Seen here is a brachiopod, a group of sessile, benthic, filter-feeding, marine invertebrates. They first appear in Cambrian rocks and were abundant in Earth's oceans throughout the Paleozoic. They were also common in Mesozoic oceans, but are scarce in modern oceanic biotas. Brachiopods have two shells, called valves, that are usually calcareous (made of calcite - CaCO3 - calcium carbonate). Each shell of a brachiopod is bilaterally symmetrical, unlike each shell of a bivalve (clam). Classification: Animalia, Brachiopoda, Articulata (a.k.a. Rhynchonelliformea), Terebratulida, Terebrataliidae Locality: 65 feet depth, offshore from La Jolla, north of San Diego, far-southern California, USA See info. at: en.wikipedia.org/wiki/Brachiopod and en.wikipedia.org/wiki/Terebratulida |
