Paterinata Rowell 1965. Linguliformea is a subphylum of inarticulate brachiopods. [1] These were the earliest of brachiopods, ranging from the Cambrian into the Holocene. They rapidly diversified during the Cambrian into the Ordovician, but most families became extinct by the end of the Devonian . The articulation in these brachiopods is lacking.MORPHOLOGY Images taken and/or modified from (moving left to right) Williams and Rowell, 1965a and Williams et. al., 1997a (combined picture), Williams and Rowell, 1965b, Shrock and Twenhofel, 1953, Williams et. al., 1997b. The following diagrams and sketches display some important brachiopod morphology.The Lingulata are inarticulate brachiopods, so named for the simplicity of their hinge mechanism. This mechanism lacks teeth and is held together only by a complex musculature. Both valves are roughly symmetrical. The genus Lingula (Bruguiere, 1797) is the oldest known animal genus that still contains extant species.

American Devonian inarticulate brachiopods was done by Hall (1859, 1860, 1867). Numer- ous other systematic papers dealing with De- vonian faunas include discussion of one or more forms. The most recent discussion was by Griesemer (1965) in his study of the Middle Devonian brachiopods of southeastern Wiscon- sin.Other articles where Inarticulata is discussed: lamp shells: Paleontology: The Inarticulata, the most abundant brachiopods of the Cambrian, soon gave way to the Articulata and declined greatly in number and variety toward the end of the Cambrian.
