Abstract
Carcharocles megalodon is considered a macropredatory shark that inhabited the seas around the world from middle Miocene to late Pliocene. In Argentina, it has only been formally recorded at two localities. Here, we report the first record for this taxon in the Buenos Aires Province. This occurrence is based on an isolated tooth recovered on the beach at the Punta Médanos locality, which lacks clear stratigraphic context. Based on the regional geology, the specimen probably came from Pliocene beds. Its size indicates that it probably belongs to a juvenile individual. Keywords: Carcharocles megalodon, macropredatory shark, fossil teeth, Mar de Ajó.
巨齿鲨被认为是一种大型鲨鱼，从中新世中期到上新世晚期居住在世界各地的海洋中。在阿根廷，只有两个地方有正式记录。在这里，我们报道了布宜诺斯艾利斯省该分类单元的第一个记录。这种情况是基于在Punta Médanos地区海滩上发现的一颗孤立的牙齿，该地区缺乏明确的地层背景。根据区域地质，该标本可能来自上新世地层。它的大小表明它可能属于一个幼年个体。关键词：巨齿鲨，大鲨鱼，牙齿化石，Mar de Ajó。
