A research team from the Institut Català de Paleontologia Miquel Crusafont, the Universitat Autònoma de Barcelona, the Naturhistorisches Museum Bern and the Université de Lyon has conducted a paleobiological study on the locomotor diversity of the first modern aspect primates. This work, that has analysed the navicular bone, located in the tarsal region, within the foot, suggests that these early species already displayed a wide range of locomotor repertoires, allowing them to exploit different niches in the arboreal milieu.
