Qianosuchus
Qianosuchus is an extinct genus of aquatic archosaur from the middle Triassic (Anisian) Guanling Formation of Pan County, China. It is represented by two nearly complete skeletons and a crushed skull.
Qianosuchus mixtus (Li et al. 2006) Middle Triassic ~230 mya)~3+m in length, was derived from a sister to Vjushkovia and was a sister to Yarasuchus and Ticinosuchus.
Distinct from Yarasuchus, Qianosuchus had shorter cervicals, a broader scapula and deeper chevrons.
Distinct from Vjushkovia, Qianosuchus had a relatively smaller skull, longer neck, shorter torso, deeper tail and more slender limbs. The rostrum was longer. The naris was located further posteriorly. The notch in the premaxilla/maxilla suture was deeper.
The dorsal scapula was double the width of the ventral portion.
The pubis was as long as the ichium. The pedes were more gracile.
