Abstract

A fossil mackerel Scomber collettei sp. nov. (Percomorpha, Scombroidei, Scombridae) is described from the Tarkhanian (lowermost Middle Miocene) of the northwestern Caucasus (Krasnodar Region, Pshekha River) based on several skeletons. This is the first discovery of a fossil representative of the genus Scomber in the Tarkhanian regional stage. The new species differs from the more ancient, late Oligocene to early Miocene mackerels from the Eastern Paratethys—S. cubanicus and S. gnarus—in having a different ratio of the abdominal and caudal vertebrae (14 + 17 vs. 15 + 16), and wider separated dorsal fins. S. collettei sp. nov. is also characterized by its unusually large teeth and lachrymal.

摘要

鲭鱼化石Scomber collettei sp。十一月 （Percomorpha，Scombroidei，Scombridae）是从高加索西北部（克拉斯诺达尔地区，普谢哈河）的塔尔汗期（中中新世最下部）以几具骨骼为基础进行描述的。这是在塔尔干地区阶段首次发现鲭鱼属的化石代表。新物种与更古老的、晚渐新世到早中新世的鲭鱼不同，它们来自于东副鲭鱼（S. cubanicus和S. gnarus），其腹椎和尾椎骨的比例不同（14 + 17 对 15 + 16），和更宽的分开的背鳍。S. collettei sp。十一月 其特征还在于其异常大的牙齿和泪液。
