The dispersal of Crocodylus from Africa to Europe during the Miocene is not well understood. A small collection of cranial fragments and postcranial elements from the latest Miocene (6.2 Ma) site of Venta del Moro (Valencia, Spain) have previously been referred to Crocodylus cf. C. checchiai Maccagno, 1947 without accompanying descriptions. Here we describe and figure for the first time the crocodylian remains from Venta del Moro, which represent at least two individuals. Our comparisons indicate that this material clearly does not belong to Diplocynodon or Tomistoma—the only two other crocodylians described so far for the European late Miocene. The material is only tentatively referred to cf. Crocodylus sp. because the apomorphies of this genus are not preserved and a referral to C. checchiai cannot be supported on a morphological basis. However, it is likely that this late Miocene species, originally described from Libya (As Sahabi) and later identified also in Kenya, could have dispersed across the Mediterranean Basin multiple times and colonized the southern areas of Mediterranean Europe, as evidenced by several Crocodylus or Crocodylus-like remains described during the past years.

来自 Venta del Moro(伊比利亚半岛)的晚中新世遗骸提供了有关鳄鱼在晚中新世特提斯大陆上的分布的进一步见解

的分散鳄鱼中新世期间从非洲到欧洲的研究还不是很清楚。来自 Venta del Moro(西班牙巴伦西亚)最新中新世(6.2 Ma)遗址的一小部分颅骨碎片和颅后元素曾被提及鳄鱼参看。C. checchiaiMaccagno,1947 年,没有附带说明。在这里,我们首次描述和描绘了来自 Venta del Moro 的鳄鱼遗骸,它代表了至少两个个体。我们的比较表明,这种材料显然不属于双棘龙要么托米斯托马——迄今为止为欧洲晚中新世描述的仅有的另外两种鳄鱼。该材料只是暂时参考cf。鳄鱼sp。因为这个属的变态没有被保存下来并且参考C. checchiai不能在形态学基础上得到支持。然而,这一中新世晚期物种,最初描述于利比亚(As Sahabi),后来也在肯尼亚发现,很可能已经多次散布在地中海盆地,并在地中海欧洲南部地区殖民,一些证据证明了这一点。鳄鱼要么鳄鱼-过去几年描述的类似遗骸。
