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.Romania has one of the highest species numbers of large branchiopods in Europe with 26 species recorded to date. The species number is wrongly stated as 28 in Demeter & Hartel (2007) .Brachiopoda. : More on Morphology. This critter "on the half-shell" shows some of the internal anatomy of a brachiopod quite well. First note the two valves or shells. All brachiopods have two shells. This makes brachiopods look superficially like bivalved molluscs (clams, oysters, etc.) However, a closer inspection shows some striking differences.
