Amphibamidae
Taxonomy
Amphibamidae was named by Moodie (1912) [Attributed to Cope (1875) in this paper and only later (Moodie, 1916, Carnegie Inst. Washington Publ. 238) formally proposed as a new family. Authority is often cited to be Moodie (1909 or 1910).]. It is not extant. It was considered paraphyletic by Anderson et al. (2008), monophyletic by Fröbisch and Reisz (2008) and Schoch (2013) and Schoch (2019).
It was assigned to Microsauria by Moodie (1912) and Moodie (1916); to Phyllospondyli by Kuhn (1946); to Dissorophoidea by Anderson et al. (2008), Fröbisch and Reisz (2008) and Anderson et al. (2008); to Dissorophoidea by Damiani and Rubidge (2003), Schoch and Rubidge (2005), Bourget and Anderson (2011) and Schoch (2013); to Xerodromes by Schoch and Milner (2014); and to Amphibamiformes by Schoch (2019) and Schoch et al. (2021).
