| This is another North American prosimian that, like Rooneyia, is hard to classify, and was seen by Szalay and Delson as being highly different from other omomyids. It is also the latest occurring native primate in the United States. The cheek teeth are remarkable because of their flatness and degree of development of accessory cusps. The last premolar and molars are also aligned in a curve, as seen from the side. This is known as the curve of Spy - significance uncertain. Szalay remarks that the appearance of the cheek teeth is convergent to that of the olingo, a carnivore related to racoons and coatimundis. |
