The most complete and best-preserved cranium of a Paleogene anthropoid ever found, that
of a small female of the early Oligocene (≈ 29–30 Ma) stem catarrhine species …

Phylogenies with estimates of divergence times are essential for investigating many
evolutionary questions. In principle,“tip-dating” is arguably the most appropriate approach …

Abstract The Fayum Depression of Egypt has yielded fossils of hystricognathous rodents
from multiple Eocene and Oligocene horizons that range in age from∼ 37 to∼ 30 Ma and …

Vertebrate paleontological research in the Fayum Depression began in 1879, with Georg
Schweinfurth's recovery of whale and fish fossils on the island Geziret el-Qarn in Birket …

Abstract Objectives Fossils from the Fayum Depression, Egypt, are crucial for understanding
anthropoid evolution due to the abundance of taxa and the time interval they represent (late …

The phylogenetic position of tarsiers within the primates has been a controversial subject for
over a century. Despite numerous morphological and molecular studies, there has been …

Revised age estimates for the primate-bearing localities of the Jebel Qatrani Formation
(Fayum area, northern Egypt) have provided a new perspective on primate response to early …

Turtles of the clade Testudinoidea have a rather scarce fossil record in Afro-Arabia, ranging
from the late Eocene up to the Quaternary. The vast majority of testudinoid fossils from Afro …

The bird fossil record is globally scarce in Africa. The early Tertiary evolution of terrestrial
birds is virtually unknown in that continent. Here, we report on a femur of a large terrestrial …

Background Gaudeamus is an enigmatic hystricognathous rodent that was, until recently,
known solely from fragmentary material from early Oligocene sites in Egypt, Oman, and …
