Qinglongtriton gangouensis

Amphibia - Temnospondyli - Urodela

Taxonomy
Qinglongtriton gangouensis was named by Jia and Gao (2016) [A basal salamandroid sharing with Beiyanerpeton derived features including: palatine present as discrete and dentate element; sensory groove present on external surface of premaxilla and maxilla; lateral surface of dentary deeply grooved; presacral vertebrae 15 in number. Differing from closely related Beiyanerpeton in having: lacrimal dorsally grooved for nasolacrimal duct; anterior ramus of pterygoid bearing teeth and directing anteromedially; ossification of orbitosphenoid absent; free operculum lacking; coronoid present as a dentate element; marginal teeth pedicellate; metacarpal II longest in manus; phalangeal formula 2-2-3-3-3 in pes. The new taxon has the basibranchial II ossified with paired anterolateral and posterolateral processes fused with a median rod as a unique feature among salamanders.]. Its type specimen is PKUP V0226, a partial skeleton (an incomplete skeleton including articulated cranium and postcranium, with part of the tail missing), and it is a 3D body fossil. Its type locality is 300 m northwest of Nanshimenzi village, which is in an Oxfordian terrestrial shale in the Tiaojishan Formation of China.
