...), in which its occurrence was known (Rathbun, 1874 , 1879 ; Clarke, 1913 ; Rezende et al., 2019a ). The common practice of ascribing Orthotetida specimens to Schuchertella led different authors to propose new taxa to include morphologies that did not fit its diagnosis. Dunbar and Condra ( 1932...

...Bernard Mottequin Abstract Brachiopods of the orders Strophomenida, Orthotetida, and Athyridida from the late middle Frasnian–early Famennian interval ( hassi to triangularis conodont zones) in the Namur-Dinant Basin (southeastern margin of Laurussia; southern Belgium) are described. Nine genera...

... and the last representatives of the Orthotetida, a major brachiopod group that disappeared during the end-Permian mass extinction. Other than two uncertain species, all taxa are new, including Meekella dongluoensis , Perigeyerella guangxiensis , Ombonia capilla , Derbyia nigpi , Schuchertella fushuiensis...

... structure as a conservative, non-reversing character implies that there are four groups of strophomenide brachiopod. The laminar-shell strophomenoids probably originated two separate times; one origination giving rise to two groups within the Strophomenida and one origination producing the Orthotetida...

For common usage and convenience, we split the following five orders into two parts: Orthida 1 and 2 (impunctate and punctuate group), Strophomenida 1 and 2 (Plectambonitoidea and Strophomenoidea), Orthotetida 1 and 2 (Orthotetidina and Triplesiidina), Pentamerida...
