Relative to the normal movement activities, the terrestrial and avian predator experiments showed fleeing movements to be very rapid with an increase in the frequency of leaping and vertical bounding. Movement distances also increased in response to the avian playback experiments. Although rare, it is possible that rapid movements may better reflect anatomical design than movements during normal daily activities.

The locomotor behavior ofT. syrichta is quite comparable to the other species of tarsiers but frequency of use of different postures and support types does seem to distinguish this species from

As such, this taxon has often been hypothesized as a basal tarsiiform on the basis of its primitive dental formula with four premolars and a simplified molar cusp pattern. Until recently [see Rose et al.: Am J Phys Anthropol 146 (2011) 281-305; Gebo et al.: J Hum Evol 63 (2012) 205-218], little was known concerning its postcranial anatomy with the exception of its well-known tarsals. In this article, we describe additional postcranial elements for T. belgica and compare these with other tarsiiforms and with primitive adapiforms. The forelimb of T. belgica indicates an arboreal primate with prominent forearm musculature, good elbow rotational mobility, and a horizontal, rather than a vertical body posture. The lateral hand positions imply grasps adaptive for relatively large diameter supports given its small body size. The hand is long with very long fingers, especiall...

Its loris-like features distinguish it from other East African material that more closely resembles galagids. Tracing the evolution of the lorisoid body has been a difficult task due to the lack of good fossil material. Here, we
