根据头骨和下颌建立了海龙一新属新种——短吻贫齿龙(Miodentosaurus brevis gen.et sp.nov.)。其正型标本是采自贵州三叠纪法郎组的一具骨架(台中自然科学博物馆标本编号NMNS-004727/F003960)。虽然头后骨胳还没有修理,但是几近完好的头骨和下颌显示出许多与众不同的特征,足以确定该标本代表了一新的海龙属种。短吻贫齿龙是个体较大的海龙,其全长超过4 m,头骨背部最长约为33 cm。吻直且极短是其最显著的特征之一。其他主要特征有:前颌骨沿前背中央有一隆嵴;上颌仅前颌骨有6枚圆锥形齿,无上颌骨齿;上颌骨沿前腹侧缘有一沟槽;下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位,头骨腭面的锄骨和翼骨均无齿,它的颈较长(至少可以辨认出13个颈椎)。这些特征显示短吻贫齿龙可能与包括中国安顺龙属(Anshunsaurus)在内的Askeptosauroidea超科有相近的系统关系。
According to the skull and jaw, a new genus of the genus Esterella (Miodentosaurus brevis gen.et sp.nov.) Was established. Its positive specimen is a skeleton collected from the Triassic Franc group in Guizhou (Taichung Natural Science Museum specimen number NMNS-004727 / F003960). Although the back of the head has not been repaired, the nearly intact skull and jaw show many distinctive features that are sufficient to make sure that the specimen represents a new species of Hella. Ankylosaurus is an individual larger dragon, its total length of more than 4 m, the skull back up to about 33 cm. Kiss straight and very short is one of its most significant features. Other main features are: the anterior ridges have a ridge along the center of the anterior back; maxillary mandibular only 6 conical teeth, no maxillary teeth; maxillary along the ventral edge of a groove; mandibular teeth are concentrated At the front and up to no more than six. According to these characteristics, it is easy to distinguish the short-kinderella from other known halons. Piton pitiful dragon skull on the top of the hole is large and very large, the hoe and wing of the skull palatal face without teeth, the neck is longer (at least 13 can identify cervical). These characteristics suggest that the kinis may be closely related to the Askeptosauroidea superfamily including Anshunsaurus in China.
