Recumbirostra is a clade of lepospondyl amphibians from the Carboniferous and Permian that includes the families Pantylidae, Gymnarthridae, Ostodolepidae, Goniorhynchidae, Brachystelechidae, and Microbrachidae. Recumbirostra was erected as a clade in 2007. It includes many lepospondyls traditionally grouped in "Microsauria", which has since been shown to be a paraphyletic grouping.〔Huttenlocker, A. K.; Pardo, J. D.; Small, B. J.; Anderson, J. S. (2013). "Cranial morphology of recumbirostrans (Lepospondyli) from the Permian of Kansas and Nebraska, and early morphological evolution inferred by micro-computed tomography". Journal of Vertebrate Paleontology 33 (3): 540. 〕 Not all phylogenetic analyses recognize Recumbirostra as a valid grouping. An alternative clade called Tuditanomorpha is occasionally supported and includes many of the same taxa.
