WAdapidae is a family of extinct primates that primarily radiated during the Eocene epoch between about 55 and 34 million years ago.
WAdapiformes is a group of early primates. Adapiforms radiated throughout much of the northern continental mass, reaching as far south as northern Africa and tropical Asia. They existed from the Eocene to the Miocene epoch. Some adapiforms resembled living lemurs.
WAdapis is an extinct genus of Adapidae primate belonging to the subfamily Adapinae. The genus was named by Cuvier in 1821 and contains up to three species. Males were larger than females.
WCaenopithecus is a genus of adapiform primate that lived in Europe during the middle Eocene.
WCantius is a genus of adapiform primate that lived in North America and Europe during the early Eocene.
WCercamoniinae is a subfamily within the extinct primate family Notharctidae primarily found in Europe, although a few genera have been found in North America and Africa.
WDarwinius is a genus within the infraorder Adapiformes, a group of basal strepsirrhine primates from the middle Eocene epoch. Its only known species, Darwinius masillae, lived approximately 47 million years ago based on dating of the fossil site.
WDonrussellia is a genus of adapiform primate that lived in Europe during the early Eocene. It is considered one of the earliest adapiforms, with D. magna sharing features with Cantius.
WEuropolemur is a genus of adapiformes primates that lived in Europe during the middle Eocene.
WGodinotia is an extinct genus of strepsirrhine primate belonging to the Adapidae family. It lived during the Eocene epoch, and its fossils have been found in the Messel Pit, Germany.
WLeptadapis is a genus of adapiform primate that lived in Europe during the middle Eocene. Fossils of the genus have been found in the Escanilla Formation of Spain and Egerkingen in Switzerland.
WNotharctidae is an extinct family of adapiform primates found primarily in North America and Europe.
WNotharctinae is an extinct subfamily of primates that were common in North America during the early and middle Eocene. The six genera that make up the group contain species that are among the most primitive of the adapiform group, which is one of the most primitive groups of primates. The evolutionary history of this subfamily has been comparatively well documented and has been used to argue for evolutionary gradualism. Though it is generally accepted that adapiforms gave rise to modern day lemurs and lorises, it is not currently known which branch of Adapiformes these living species are most closely related to. Notharctines became extinct in the middle Eocene, most likely because of a combination of factors including climatic change and competition with other North American primates.
WNotharctus is a genus of adapiform primate that lived in North America and Europe during the late to middle Eocene.
WNotharctus tenebrosus was an early primate from the early Eocene, some 54–38 million years ago. Its fossil was found by Ferdinand V. Hayden in 1870 in southwestern Wyoming. When first found, Notharctus tenebrosus was thought to be a small pachyderm due to the concentration of pachyderm fossils in the area. However, after Walter W. Granger's discovery of a nearly complete skeleton, also in Wyoming, it was firmly established as a primate. Notharctus tenebrosus most resembles modern-day lemurs, although they are not directly related.
WProtoadapis is a genus of adapiform primate that lived in Europe during the early middle Eocene.
WSmilodectes is a genus of adapiform primate that lived in North America during the middle Eocene. It possesses a post-orbital bar and grasping thumbs and toes. Smilodectes has a small cranium size and the foramen magnum was located at the back of the skull, on the occipital bone.
