Recumbirostra is a clade of lepospondyl amphibians from the Carboniferous and Permian that includes the families Pantylidae, Gymnarthridae, Ostodolepidae, Goniorhynchidae, Brachystelechidae, and Microbrachidae.[1] 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.[2][3] 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.[4] Below is a cladogram showing the phylogenetic relationships of recumbirostrans from Glienke (2012):[1]

Most authors consider recumbirostrans to be lepospondyl amphibians; however, phylogenetic analyses conducted by Pardo, Szostakiwskyj and Anderson (2015) and Pardo et al. (2017) recovered them as sauropsid amniotes instead.[5][6]
