Metric features (in millimetres) of the CBI-1-545 talus from the Djebel Chambi CBI-1 locality.

This primate tarsal specimen is attributed to Djebelemur martinezi. T-Neck-angle and talar measurements follow the works of Gebo et al. [75]. The angle between the fibular facet and lateral tibial facet (SFF-angle) is after Boyer et al. [73]. The talus was measured with a microscope fitted with a calibrated reticle (Measuroscope Nikon 10).
1Distance from the most lateral point on the fibular facet (laterally projecting talar process) to the most medial point on the tibial facet.
2Perpendicular distance from the most dorsal aspect of the medial trochlear margin to a chord connecting the most plantar point on the medial talar body to the plantar aspect of the talar head.
3Perpendicular distance from the most dorsal point on the lateral trochlea margin to the chord defining the most plantar extent of the anterior and posterior aspects of the ectal facet.
4Maximum mediolateral width.
5Maximum dorsoplantar height.
6Medial deviation of the talar neck relative to the anteroposterior axis of the trochlea.
7Dorsolateral rotation of the talar head relative to the mediolateral axis of the dorsal trochlea.
8Position of the posterior calcaneal facet relative to the talar neck.
9Angle between the plane of the fibular facet relative to that of the lateral tibial facet.
