Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. C. Fox and B. G. Naylor 1982 | Small, tailed amphibians having limbs; teeth pleurodont, chisel-like, non-pedicellate; dentaries with lobate, interdigitating symphysis; quadrate-articular joint strongly convexo-concave; large lacrimal, extending between naris and orbit and bearing broad external groove; frontals fused; parietals with postorbital process; first three cervical vertebra uniquely specialized; rib-bearers on dorsal vertebrae unicipital. | |
| J. D. Gardner 2000 | Clade of lissamphibians differing from all other vertebrates in the following two autapomorphies: mortise and tenon style intermandibular joint and first three vertebrae comprised ofan atlas lacking postzygapophyses and having posterior cotyle with articular face indented by tripartite facets and dorsal and ventrolateral margins deeply emarginate, a neomorphic 'axis' lacking neural arch and transverse processes, and first trunk vertebra lacking prezygapophyses, but having anterior end of neural arch extending craniad above axis to fit into complementary notch in posterior edge of atlantal neural arch. Differs from other temnospondyls in five synapomorphies: crowns on marginal teeth labiolingually compressed and distally bear three faint cuspules arranged mesiodistally; joint between skull and mandible nearly vertical; and frontals fused, with prominent internasal process and two pairs of slots for mortise and tenon contact with paired nasals anteriorly and paired prefrontals anterolaterally. Differs further from some amphibamids and most lissamphibians in one homoplasy: marginal teeth non-pedicellate in adults. Among lissamphibians, lacks respective autapomorphies of gymnophionans, caudates, and salientians; more derived than gymnophionans and resembles caudates and batrachians in lacking surangular, splenials, and coronoids, but differs from last two groups in primitively retaining a posteriorly closed maxillary arcade, concave articular receiving convex quadrate, more than 20 presacral vertebrae, ossified pubis, and dermal scales. Primitively differs further from apodans, anurans, and many urodeles in retaining lacrimal and from apodans, salientians, and some urodeles in retaining odontoid process. |
