 Only the first 31 tail vertebrae are preserved, out of at least 42-48 vertebrae that are expected to comprise the tail based on other closely related pachypleurosaurs, which implies a total body length longer than 80 cm for this individual.NMNS-KIKO-F044630 was discovered in 2006 near the Huangnihe River at Chajiang of Xingyi, southwestern-most Guizhou Province.It was most probably collected from the Zhuganpo Member of the Falang Formation based on field expeditions to the area in 2006, somewhere between the Geju railway station and Chajiang railway station along the east side of the river which is the provincial boundary between Guizhou and Yunnan, thus dating to the Ladinian stage of the late Middle Triassic, about 238 million years ago.
