This project links to 3D imagery of all the fossil toe tips (distal phalanges) analyzed in the linked Journal of Human Evolution paper by Boyer and colleagues (2018). The key finding is 7 distal phalanges (representing 5 genera) that appear to have belonged to early Eocene omomyids and sported grooming claws. This is the first evidence that omomyids had grooming claws. This evidence strongly indicates that grooming claws were present in the ancestral primate and that grooming claws evolved from primitive claws.
