New large−bodied mammals from the late Oligocene site of Chilga, Ethiopia
Newly recovered fossil proboscideans and embrithopods from Chilga, Ethiopia are described and evaluated taxonomi− cally. They are dated to ca. 28–27 Ma (late Oligocene), temporally intermediate between late Eocene–early Oligocene Afro−Arabian faunas dominated by archaic, endemic taxa, and replacement faunas of the early Miocene marked by a mas− sive influx of Eurasian migrants. The paucity of s...

متن کاملPaleoenvironment of the earliest hominoids: new evidence from the oligocene avifauna of egypt.
Analysis of fossil birds from the Oligocene Jebel Qatrani Formation in the Fayum depression of Egypt, site of the oldest known hominoid primates, allows precise paleoenvironmental reconstruction of the climatic and biotic conditions that influenced some of the earliest stages of hominoid evolution. Unlike the fossil mammals of the Fayum, which belong largely to extinct groups, most of the birds...
متن کاملMammals from the Blue Ash Local Fauna (late Oligocene), South Dakota. Rodentia, Part 2: Families Florentiamyidae and Geomyidae
Three species of florentiamyid, Florentiamys sp. cf. F. kingi Wahlert, Kirkomys parvus (Troxell), and Hitonkala martintau n. sp., and an undetermined species of geomyid are recognized from the Blue Ash fauna. This increases the total number of rodents described from this fauna to 14. Florentiamys sp. cf. F. kingi is similar in morphology to the Arikareean F. kingi, but is slightly smaller. This...
متن کاملA new emu (Dromaiinae) from the Late Oligocene Etadunna Formation
A new emu (Emuarius guljaruba, sp. nov.) is described from the Late Oligocene Etadunna Formation (Ngama Local Fauna), based on a complete tarsometatarsus. While exhibiting evidence of cursorial abilities advanced over those of cassowaries (Casuarius), this taxon was not as cursorially adapted as the living Emu (Dromaius novaehollandiae). This taxon is provisionally referred to the genus Emuariu...
