The early anthropoid species initially described asAegyptopithecus zeuxis Simons, 1965, from the Oligocene of Egypt, although retained by many authors in the monotypic genusAegyptopithecus, has been lumped by others into the genusPropliopithecus. Similarly, the species originally described asParapithecus grangeri Simons, 1974, has been ranked by some authors in a monotypic genusSimonsius, while others retain it inParapithecus. Criteria to be considered in resolving these taxonomic debates are… 
The Cranium and Adaptations of Parapithecus grangeri, a Stem Anthropoid from the Fayum Oligocene of Egypt
A nearly complete cranium of an early anthropoid from the Fayum badlands of Egypt that belongs to the species Parapithecus grangeri is described and some postcranial bones have been identified and are evaluated here to present new absolute body mass estimates for this primate.
Intraspecific Variation of One of the Oldest Litopterna (Mammalia), Protolipterna ellipsodontoides, and Redescription of the Species
Major dental variation present for Protolipterna ellipsodontoides Cifelli (Litopterna) is described based on a sample of more than 500 teeth and a differential diagnosis distinguishing the species from its sister taxa is provided.
The zoogeographic and phylogenetic relationships of early catarrhine primates in Asia
The pliopithecoids were the first catarrhines to migrate out of Africa at ~18–20 Ma, while contemporary proconsulids and dendropithecids may have been restricted to Afro-Arabia, and new material from China, may possibly have closer ties with dendropycids, proConsulids, or hylobatids.
Family-Group Names for Bees (Hymenoptera: Apoidea)
The name Anthophila, as proposed by Latreille, is adopted for the bees as a whole and the suggested current usage of all available family-group names is appended.
Primates in northern Viet Nam: A review of the ecology and conservation status of extant species, with notes on pleistocene localities
We discuss the distribution of living and fossil primates in northern Viet Nam, integrate new localities into the known ranges, and address the ecological parameters and status of extant primate
The Evolution of High Visual Acuity in the Anthropoidea
While the tarsier visual system is primarily specialized for enhanced sensitivity in the context of nocturnal visual predation (Castenholz, 1984s), most living anthropoids are adapted for extremely acute diurnal vision.
Convergence and Frontation in Fayum Anthropoid Orbits


A revision of the Oligocene apes of the Fayum Province, Egypt
A systematic revision of the earliest apes is presented and the possibility of a separate gibbon or hominid lineage going back to the Oligocene is unlikely on present evidence.
A new species of Propliopithecus from the Fayum, Egypt.
Propliopithecus ankeli is characterized by increased relative size and robustness of the antemolar dentition, which contrasts with the pattern observed in the Fayum's other large hominoid, A. zeuxis, and probably represents a lineage not ancestral to other Fayum hominoids.
The ecology of oligocene African anthropoidea

Based on the hominoid analogy, the molar morphology of the Fayum species is consistent with a frugivorous diet, and the particularly high molar crowns of Parapithecus grangerisuggest that this species may have foraged on the ground to a considerable degree.
The humerus of Aegyptopithecus zeuxis: a primitive anthropoid.
In most features, the humerus of Aegyptopithecus zeuxis is more primitive than the hypothetical last common ancestor of extant cercopithecoids and hominoids based on neontological comparisons.
A new species
The only previously known species of Myrsidea from bulbuls, M. warwicki ex Ixos philippinus, is redescribed and sixteen new species are described; they and their type hosts are described.
The stuttgart collection of oligocene primates from the fayum province of Egypt
In 1907, R. Markgraf made a small collection of Oligocene fossil primates from Egypt for the Staatliches Museum für Naturkunde in Stuttgart. Circumstances of discovery suggest that this collection
Skeletal remains of Propliopithecus chirobates from the Egyptian Oligocene.

Skeletal elements from Oligocene sediments in the Fayum Province of Egypt are attributed to Propliopithecus chirobates, indicating that this species was an arboreal quadruped.
