摘要

目前的贡献的目的是描述部分化石头骨属于鲶鱼属Sorubim。该标本来自阿根廷恩特雷Ríos省帕拉南地区晚中新世Ituzaingó组。这里描述的材料(MACN Pv-14224)被确定为属，因为Sorubim的现存物种在形态上相似。Sorubim的存在与大多数现存的胡椒属在晚中新世已经存在的假设相一致。目前的发现构成了该属的第一个化石记录。

First fossil record of the catfish genus Sorubim (Siluriformes, Pimelodidae), from the Late Miocene of Paraná, Northeastern Argentina

The aim of the present contribution is to describe a partial fossil skull belonging to the catfish genus Sorubim. The specimen originates from the Late Miocene Ituzaingó Formation, at Paraná locality, Entre Ríos Province, Argentina. The material described here (MACN Pv-14224) was determined just to genus because the living species of Sorubim are morphologically similar. Presence of Sorubim is in concordance with the hypothesis indicating that most extant pimelodid genera were already present by the Late Miocene. Present finding constitutes the first fossil record for the genus.
