记述的山东少鳞鳜（新种）（Ｃｏｒｅｏｐｅｒｃａ ｓｈａｎｄｏｎｇｅｎｓｉｓ ｓｐ．ｎｏｖ）是该属化石在我国的首次发现，标本产自山东山旺早中新世晚期山旺组纹层状硅藻页岩之上的含硅藻泥页岩中。山东少鳞鳜的发现，说明原始鳜类在中新世已发生分化，在中新世时期的中国大陆和日本列岛均已相当繁盛。少鳞鳜属可能并非起源于朝鲜和日本一带，之后扩散到中国，而是中新世广布于东亚的鱼类，这进一步支持了关于中国东部和日本列岛新生代晚期同属一个鱼类区系的观点。
The recorded Coreoperca shandongensis sp. Nov is the first discovery of this fossil in our country. The specimen was from the Shangwang Formation lacustrine shale Diatom mud shale. The discovery of Scylla spp. In Shandong shows that the primitive Scabia species had diverged in the Miocene, and both the Chinese mainland and the Japanese archipelago in the Miocene period have been fairly prosperous. Scirpus probably did not originate in North Korea and Japan, but then spread to China but rather to the Pliocene fish widely distributed in East Asia, further supporting the fact that the late Cenozoic of both eastern China and Japan belong to the same fish fauna the opinion of.
