Similar monogeneric families were also erected for other small, terrestrial dissorophoids (e.g., Doleserpetontidae), and most of the taxa now recognized as amphibamiforms were placed within the Dissorophidae.

[6] Schoch (2018) erected the new clade Amphibamiformes to include the traditional amphibamids and the nested branchiosaurids and subsequently restricted the Amphibamidae to two taxa: Doleserpeton annectens from the Dolese Brothers Limestone Quarry near Richards Spur, Oklahoma and Amphibamus grandiceps from Mazon Creek, Illinois.

Olsoniformes Eoscopus Platyrhinops Tersomius Pasawioops Micropholis Doleserpeton Amphibamus Gerobatrachus Georgenthalia Eocaecilia Karaurus Triadobatrachus Branchiosaurus Apateon Leptorophus Schoenfelderpeton [1] The Amphibamidae have typically been recovered close to some or all of the lissamphibian crown.

[7] Below is a modified cladogram from Anderson et al. (2008) showing Batrachia nested in the Amphibamidae, with Gerobatrachus as the sister taxon of Batrachia (anurans and caudates) and Doleserpeton and Amphibamus as successive outgroups:[7] Tersomius Micropholis Eoscopus Platyrhinops Amphibamus Doleserpeton Gerobatrachus Anura Triadobatrachus Caudata Albanerpetontidae There is continued debate over the origin of lissamphibians, including whether they are monophyletic or whether batrachians and caecilians are descended from different clades of tetrapods or temnospondyls.

[8] If they are monophyletic, there is also a debate about which clade they are nested in, with some hypotheses suggesting a lepospondyl origin, in which case amphibamids would not be closely related to any extant amphibians.
