Brachiopod or bivalve? Brachiopods (or Brachiopoda) are often confused with bivalved mollusks (clams or Bivalvia). However, there are major biological differences between brachiopods and bivalves.

May 20, 2016 · A brachiopod fauna from the upper part of the Nakazato Formation, southern Kitakami Mountains, northeast Japan, is nearly similar to the fauna from the top of the Yikewusu Formation (upper Eifelian) in the Zhusilenghaierhan region, western Inner Mongolia. Spirifer is a genus of marine brachiopods belonging to the order Spiriferida and family Spiriferidae. Species belonging to the genus lived from the Middle Ordovician (Sandbian) through to the Late Triassic (Carnian) with a global distribution. They were stationary epifaunal suspension feeders.

In the extant articulate brachiopods, the tentacles of the lophophore lack supporting structures such as muscle fibres or bones (Reed & Cloney, 1977; Williams, 1997a). To avoid deflection of tentacles by water flow, a slower internal flow appears to have preferred for feeding in articulate brachiopods (LaBarbera, 1977; Dhar et al., 1997).

Brachiopods have one of the longest histories and best fossil records of all invertebrates.
