The host says that there is a 6-million-year gap in the fossil evidence between the latest Oligocene catarrhines and the earliest Miocene proconsulids, which could mean that primates disappeared from Earth and evolved anew some time later.

Quick review: I feel better for having read this. Longer review: If only monotheism had been historically more informed by the concepts of ancient Greeks, perhaps there would have been less intolerance and conflict between creeds and we wouldn't now find ourselves (in the west) in a culture playing an endlessly stuck record of vacuous controversy between theists and atheists/5.

The Desmostylia (from Greek δεσμά desma, "bundle", and στῦλος stylos, "pillar") are an extinct order of aquatic mammals that existed from the early Oligocene to the late Miocene. Desmostylians are the only known extinct order of marine mammals (Thalassocnus, a genus of marine sloths, became extinct more recently).

The Desmostylia, together with Sirenia and Class: Mammalia. Introduction to the Desmostylia: The Desmostylia are an extinct group of marine are both strange and enigmatic creatures known only from deposits of the Late Oligocene and the s assigned to four genera have been found in Japan and along the west coast of Mexico and the United States, to as far north as Washington.

Behemotops (from the Biblical monster Behemoth, by Linnaeus and others believed to be a hippo) is an extinct genus of herbivorous marine lived from the Early Oligocene through the Late Oligocene ( mya—23 Mya), existing for is the most primitive known desmostylian, believed to be close to the ancestry of all other : Mammalia.

The Desmostylia are the only completely extinct order of marine mammals. They were hippopotamus-like amphibious herbivores that were confined to the North Pacific Ocean and are known only as fossils of Oligocene and Miocene age.[For comprehensive references to the published literature on desmostylians, see Domning ().].

The other trend was mostly confined to South America, which was isolated from North America during the Oligocene epoch (the Central American land bridge would not form for another 20 million years) and hosted a bizarre array of megafauna mammals, including the elephant-like Pyrotherium and the meat-eating marsupial Borhyaena (the marsupials of Oligocene South.

The late Oligocene Deseadan record includes two major groups that are thought to represent early waif dispersals from other continents. One of these, the caviomorph rodents (e.g., porcupines, capybaras, chinchillas, and a wide assortment of smaller forms), was the only group of rodents in South America until the Plio-Pleistocene.

The dispersal history of Malagasy lemurs and South American platyrrhines demonstrates that primate dispersal into new terrains often sparks adaptive radiation and morphological innovation. The precocious (Paleocene) dispersal of basal anthropoids from Asia to Africa may have instigated an adaptive radiation that yielded the modern anthropoid Cited by: Two new Oligocene desmostylians and a discussion of tethytherian systematics.
