记述了产自贵州关岭法郎组瓦窑段(上三叠统)短吻贫齿龙一新材料。新标本头后骨骼十分完整,使我们对该海龙的全身骨骼形态有了一个完整的认识,尤其是澄清了其肩带及前、后肢的解剖学特征。短吻贫齿龙牙齿稀少且局限于上、下颌的前端,以及末端指/趾骨(爪)扁平等性状表明,该种不是纯粹的肉食动物。依据新材料,短吻贫齿龙在局部形态上存在个体变异,并确认后肢趾趾式(2-3-4-5-5)可作为该海龙的特征之一。
Described a new material from the short-toothed dragon in the Paleo-karst section of the Guanling Fm in Guanling, Guizhou Province (Upper Triassic). The skeleton of the new specimen is very intact, giving us a complete understanding of the skeleton shape of the dragon. In particular, it clarifies the anatomic features of its shoulder straps and anterior and posterior limbs. Short spines Odontosaurus teeth sparse and limited to the upper and lower jaws of the front, as well as the distal finger / phalanges (claws) flat traits show that the species is not a purely carnivore. According to the new material, there are individual variations in the local morphology of the genus Agnostic, and it is confirmed that the toe (2-3-4-5-5) of the hindlimb can be used as one of the characteristics of this genus.
