The phylum Brachiopoda is divided into three subphyla: Linguliformea, Craniiformea and Rhynchonelliformea. Although they were extremely common throughout the Paleozoic, today they are considered a minor phylum, and only five orders have extant representatives: Lingulida, with two families, 6 ...restore Hatschek's original rank of phylum for the group, with the brachiopods, bryozoans and phoronids consequently reduced in hierarchical status to classes (Emig 1984). More recently, Conway Morris & Peel (1995, pp. 343-344) concluded that brachiopods evolved from extinct protostomes, the early Cambrian articulated halkieriids.

Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group.

Brachiopods represent an animal phylum of benthic marine organisms that originated in the Cambrian. About 400 recent species are known from today’s oceans (Emig et al., 2013). Around 5000 fossil genera have been described, as brachiopods were dominant in the benthic marine environment during the Palaeozoic (Logan, 2007). Brachiopods have a biphasic life cycle with a planktonic larvae and ...Brachiopods, often referred to as "lampshells," are a group of marine invertebrates that have existed on Earth for over half a billion years.
