Abstract

The skeleton of a berycomorph fish of the Melamphaidae family was found in sediments of the Middle-Upper Miocene of the Kurasi Formation of Sakhalin Island, Russia. Morphological features, such as a short tall body with a large head, the presence of one dorsal fin with a short base, 19 principal caudal rays, a small number of vertebrae, and single-row jaw teeth in combination with very large cycloid scales enable the assignment of this fossil to the modern genus Scopelogadus. This is the second known record of a fossil skeleton for both the genus Scopelogadus and the family Melamphaidae. The fossil locality is placed approximately 17 degrees north of the range of extant species of the genus. The presence of scopelogadus fish in the Kurasi Formation complex suggests that the accumulation depth of its deposits was at least 200 m.

来自俄罗斯萨哈林岛新近纪沉积物的Scopelogadus属化石Melamphaid鱼（Teleostei：Melamphaidae）

摘要

在俄罗斯的萨哈林岛的库拉西组中上新世中部沉积物中发现了一种美amp纲科的拟变体鱼的骨骼。形态特征，例如高个头的矮个子高矮的身体，一个短鳍的背鳍，19条主尾鳍，少量椎骨和单行颚齿以及非常大的摆线鳞片将此化石归入现代Scopelogadus属。这是Scopelogadus属的化石骨架的第二个已知记录和家庭Melamphaidae。化石的位置位于该属现存物种范围以北约17度。库拉西组群中存在对白对虾鱼类，表明其沉积物的堆积深度至少为200 m。
