Semicircular canal system in early primates.
Fossil primates reconstructed are reconstructed as having been similarly agile to omomyids and derived notharctid adapoids, which suggests that when postcranial material is found for this species it will exhibit features for some leaping behaviour, or for a locomotor mode requiring a similar degree of agility.

A Summary of Adapiform Systematics and Phylogeny
A new classification is proposed for the 30 genera of adapiforms, containing three families: Notharctidae, Adapidae and Sivaladapidae; and one subfamily of uncertain affinities, the new Pronycticebinae, which is based on the particular characters of the skull of PronYcticebus gaudryi, and four genera are proposed as adapids outside the European adapine radiation. Expand
Interrelationships among primate higher taxa
Features of the ankle and wrist joints of several adapiform taxa provide an independent test of the preceding hypotheses and suggest that lemuriforms are monophyletic with respect to knownAdapiforms, but that adAPiforms nevertheless are their stem lineage (sensu Ax26). Expand
Early North African Primates and Their Significance for the Origin of Simiiformes (= Anthropoidea)
Twelve years ago, just after the publication of the volume dedicated to platyrrhine origins (Ciochon and Chiarelli, 1980), Hoffstetter made a remarkable attempt to synthesize information and debatesExpand
Earliest known simian primate found in Algeria
The discovery of a new, diminutive and much older simian from an Algerian locality, Glib Zegdou, confirms predictions about the great antiquity of Simiiformes7–9 and emphasizes a long and endemic African history for higher primates. Expand
Lemuriform Origins as Viewed from the Fossil Record

  • 1 October 2006
A reasonable scenario can be proposed: tooth comb differentiation and lemuriform dispersal to Madagascar between 52–40 million years ago and the possible significance of Plesiopithecus for daubentoniid origins is raised. Expand
Eutherian tarsal bones from the Late Cretaceous of India
Eutherian tarsal bones of Late Cretaceous age are reported for the first time from sedimentary beds intercalated with the Deccan Traps of peninsular India. The tarsal bones, represented mainly byExpand
Biometrical characteristics of primate hands
The length proportions of the primate hands and their elements are analyzed in 43 extant genera and 6 fossil genera, finding that paraxony is the most frequent pattern of the simiiform hand, whereas hypermesaxony characterizes humans, hylobatids, and tarsiers. Expand
Fossil primate hands: A review and an evolutionary inquiry emphasizing early forms
In euprimates, this work describes the strepsirhine morphotype hand, characterized by a relatively high degree of pollical divergence, features of the ulnocarpal articulation that imply an enhanced capacity for ulnar deviation, and relatively long digits; this hand is specialized for grasping. Expand
Early euprimate hands in evolutionary perspective
The simiiform hand is probably not derived from a prosimian grasping hand, a view which seems to be corroborated by the mode of locomotion in Adapis and is in agreement with Napier's analyses. Expand
