Actinopterygii 輻鰭魚綱

Semionotiformes 半椎魚目

Semionotidae 半椎魚科

Asialepidotus 亞洲鱗齒魚屬

年代：三疊紀(Late Triassic, 270~ 210 mya)

產地：中國雲南、貴州 (Yunnan & Guizhou province , China)

興義亞洲鱗齒魚化石於 1957 年於興義頂效鎮綠蔭村首次發現，之前大多將其歸類於弓鰭魚目之下，但是最新研究是歸屬於半椎魚目下。它是上揚子區三疊紀中期最繁盛和個體最大的一種似鲱魚類。

興義亞洲鱗齒魚的特徵是：身體成高紡錘形，所有鰭的棘鱗都不發達，頭骨外部骨片和鱗蓋的表面具有細小的疣突。口裂大、上頷可活動，有一塊較大的輔上頷骨，眶後有兩塊次眶骨。兩塊次眶骨與前鰓蓋骨組成的外形類似早期副半椎魚的卵形前鰓蓋骨。鰓蓋骨略呈長方形，下鰓蓋骨較上鰓蓋骨小。間鰓蓋骨呈三角形，軀幹前部之側鱗略呈長方形。
