The almost complete skeleton of a fossil dreamer, identified as Oneirodes sp., is described from the middle–upper Miocene Kurasi Formation of southern Sakhalin Island, Russia. This is the second fossil skeletal record of oneirodid anglerfishes following those described from the Puente Formation of California, USA. The new specimen possesses morphological features very similar to those of the recent and fossil members of its genus, and cannot be separated from them at the species level. This finding confirms the idea of the high level of speciation of this fish family prior to the middle–late Miocene and demonstrates the wide geographic distribution of the genus Oneirodes already at this time.

来自俄罗斯萨哈林岛中新世的梦龙属 (Lophiiformes: Ceratioidei) 的化石梦想家

一个化石梦想家的几乎完整的骨架，被确定为梦露sp.，描述于俄罗斯库页岛南部的中上中新世库拉西组。这是继美国加利福尼亚州普恩特组所描述的之后，第二个通神琵琶鱼的骨骼化石记录。新标本的形态特征与其属的近期和化石成员非常相似，在物种层面上无法与之分开。这一发现证实了该鱼科在中新世中晚期之前高度物种形成的想法，并证明了该属的广泛地理分布梦露已经在这个时候了。
