Agorophiidae
''Agorophius'' is an extinct genus of toothed whale that lived during the Oligocene period, approximately , in the waters off what is now South Carolina. Taxonomy The holotype of ''Agorophius pygmaeus'', MCZ 8761, was first mentioned in an 1848 report on the geology of South Carolina by Michael Tuomey. It was eventually described as ''Zeuglodon pygmaeus'' by Johannes Peter Müller in 1849. Louis Agassiz coined the name ''Phocodon holmesii'' for the same specimen, classifying it as an odontocete. Later authors considered ''Zeuglodon pygmaeus'' a species of either ''Dorudon'' or ''Squalodon ''Squalodon'' is an extinct genus of whales of the Oligocene and Miocene epochs, belonging to the family Squalodontidae.

Xenorophus
''Xenorophus'' is a genus of primitive odontocete from late Oligocene ( Chattian) marine deposits in South Carolina belonging to Xenorophidae. Classification ''Xenorophus'' was originally described on the basis of a skull from the Chandler Bridge Formation of South Carolina in the collections of the USNM. Later authors, but also Remington Kellogg who described the genus, classified it in the family Agorophiidae ''Agorophius'' is an extinct genus of toothed whale that lived during the Oligocene period, approximately , in the waters off what is now South Carolina. Taxonomy The holotype of ''Agorophius pygmaeus'', MCZ 8761, was first mentioned in an 1848 ..., which eventually became a repository for primitive odontocetes. Whitmore and Sanders (1977) and Fordyce (1981), however, preferred to treat ''Xenorophus'' as Odontoceti ''incertae sedis''. A cladistic analysis by Mark Uhen published in 2008 recognized ''Xenorophus'' as belonging with '' Archaeodelphis'' and '' Albertodelp ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Cetacean Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...
