Fossils from the Fayum Depression, Egypt, are crucial for understanding anthropoid evolution due to the abundance of taxa and the time interval they represent (late Eocene to early Oligocene). Dietary and foraging behavioral interpretations suggest fruits were their dominant food source, although hard foods (e.g., seeds and nuts) and leaves could have been important dietary components for particular groups. In this study, we compare dental chipping patterns in five Fayum primate genera with chipping data for extant primates, to assess potential hard object feeding in early anthropoids.

牙齿碎裂模式和龋齿表明早期类人猿以软水果饮食

埃及法尤姆凹陷的化石对于了解类人猿的进化至关重要，因为它们具有丰富的类群和它们所代表的时间间隔（始新世晚期到渐新世早期）。饮食和觅食行为的解释表明，水果是他们的主要食物来源，尽管硬质食物（例如种子和坚果）和叶子可能是特定群体的重要饮食成分。在这项研究中，我们将五个法尤姆灵长类动物属的牙齿碎片模式与现存灵长类动物的牙齿碎片数据进行比较，以评估早期类人猿潜在的硬物摄食。
