Adapidae
Adapidae is a family of extinct primates that primarily radiated during the Eocene epoch between about 55 and 34 million years ago. Adapid systematics and evolutionary relationships are controversial, but there is fairly good evidence from the postcranial skeleton (everything but the skull, or cranium) that adapids were stem strepsirrhines (members of the group including the living lemurs, lorises, and bushbabies). In particular, the anatomy of the adapid wrist and ankle (e.g., position of the groove for the flexor fibularis tendon on the talus, the presence of a sloping talo-fibular facet) show derived similarities with those of living strepsirrhines. However, adapids lacked many of the anatomical specializations characteristic of living strepsirrhines, such as a toothcomb,Rose, K. D., A. Walker, and L. L. Jacobs. 1981. Function of the mandibular tooth comb in living and extinct mammals. Nature 289:583-585. a toilet-claw A grooming claw (or toilet claw) is the specialized cla ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Darwinius
''Darwinius'' 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 (Lutetian stage) based on dating of the fossil site. The only known fossil, called Ida, was discovered in 1983 at the Messel pit, a disused quarry near the village of Messel, about 35 km (22 mi) southeast of Frankfurt, Germany. The fossil, divided into a slab and partial counterslab after the amateur excavation and sold separately, was not reassembled until 2007. The fossil is of a juvenile female, approximately overall length, with the head and body length excluding the tail being about . It is estimated that Ida died at about 80–85% of her projected adult body and limb length. The genus ''Darwinius'' was named in commemoration of the bicentenary of the birth of Charles Darwin, and the species name ''masillae'' honors Messel where the specimen was f ...

Europolemur
''Europolemur'' is a genus of adapiform primates that lived in Europe during the middle Eocene. Morphology ''Europolemur klatti'' is part of a group of long-digited fossils that most likely approximates early euprimate hand proportions. ''E. klatti'' has a grasping hallux and there is evidence that it may have had nails rather than claws. This implies that stabilizing the tips of the digits and hand must in some way have been important for its lifestyle in its habitat. Relative to the forearm, the hand of ''E. klatti'' was large, which may be related to vertical climbing or posture. The shape of the calcaneus resembles that found in '' Smilodectes'' and '' Notharctus''. ''E. klatti'' had an average body mass of 1.7 kilograms. Dentition In 1995, two isolated upper molars belonging to ''E. klatti'' were found in an old lake deposit during excavations by the "Naturhistorisches Museum Mainz/Landessammlung für Naturkunde Rheinland-Pfalz". The museum determined that the molars ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Masradapis
''Masradapis'' is an extinct genus of caenopithecine primate from the Priabonian Birket Qarun Formation of the Fayum Depression, Egypt Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediter .... The type and only species, ''Masradapis tahai'', was named and described by Erik R. Seiffert ''et al.'', in 2017. Bayesian tip-dating, when combined with Bayesian biogeographic analysis, suggests that a common ancestor of known caenopithecines dispersed to Afro-Arabia from Europe between 49.4 and 47.4 Ma, and that a trans-Tethyan back-dispersal explains ''Caenopithecus''’ later presence in Europe.
