Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. M. Báez and B. Sanchiz 2007 | Small anuran that shares only with pipoids the joint presence of an azygous frontoparietal and a parasphenoid lacking subotic alae, but differs from them in having 9 presacral vertebrae. It differs from Rhadinosteous and rhinophrynids in having the atlas formed by fusion of Vertebrae I and II, and metacarpals exceeding 75% the length of the radioulna. It differs from all known pipimorphs in the presence of a complete maxillary arch and can be further distinguished from crown pipids in the presence of a T−shaped squamosal, pedicellate teeth, a parahyoid bone, and a bicondylar articulation between sacrum and urostyle. It also differs from Thoraciliacus and Cordicephalus in its narrower braincase, a frontoparietal forming a flat dorsal table, and tiny scapular cleft and it can be distinguished from palaeobatrachids in having a T−shaped squamosal lacking processes on the ventral ramus, an articulation for the lower jaw at the midlevel of the otic capsules, a monovertebral sacrum, slightly expanded sacral diapophyses, and a coracoid lacking a conspicuous rostral process and having a slightly expanded sternal end. |
