Crenatosiren
''Crenatosiren'' is an extinct genus of dugongid sirenian known from the late Oligocene (Chattian) of Florida, North Carolina, and South Carolina. The type and only known species is ''Crenatosiren olseni''. Taxonomy ''Crenatosiren'' was originally named ''"Halitherium" olseni'' by Rinehart (1976), who described the species from marine deposits of the late Oligocene (Arikareean NALMA) Parachucla Formation in the Suwannee River in Hamilton County, Florida. Domning (1991) eventually recognized the taxon as more derived than the ''Halitherium'' type species and assigned it to the new genus ''Crenatosiren'', classifying it as a relative of the dugongid '' Rytiodus''.R. H. Reinhart. 1976Fossil sirenians and desmostylids from Florida and elsewhere Bulletin of the Florida State Museum Biological Sciences 20(4):187-300 The genus name is derived from the Latin words ''crenatus'' (meaning 'notched') and ''siren''. More specimens of ''C. olseni'' were later found in the Ashley and Chandler B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Chattian
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appearance o ...

Suwannee River
The Suwannee River (also spelled Suwanee River) is a river that runs through south Georgia southward into Florida in the southern United States. It is a wild blackwater river, about long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 18, 2011 The Suwannee River is the site of the prehistoric Suwanee Straits that separated the panhandle from the continent. Geography The headwaters of the Suwannee River are in the Okefenokee Swamp in the town of Fargo, Georgia. The river runs southwestward into the Florida Panhandle, then drops in elevation through limestone layers into a rare Florida whitewater rapid. Past the rapid, the Suwanee turns west near the town of White Springs, Florida, then connects to the confluences of the Alapaha River and Withlacoochee River. The confluences of these three rivers form the southern borderline of Hamilton County, Florida. The Suwanee then bends southward near the town of Ellavi ...

Rytiodus
''Rytiodus'' (meaning ''Rytina'', "wrinkled", an old name for Steller's sea cow) is an extinct genus of sirenian, whose fossils have been discovered in France, Europe and Libya. Description With a length of , ''Rytiodus'' was about twice the size as modern sirenians, surpassed only by Steller's sea cow, which was up to long. Like its closest modern relatives, the dugongs, ''Rytiodus'' had a pair of flippers, a streamlined body and a tail fin. Its flattened snout allowed it to feed in shallow coastal waters. ''Rytiodus'' had short tusks which it may have used to extract food from the sand. See also *Evolution of sirenians References *Barry Cox, Colin Harrison, R.J.G. Savage, and Brian Gardiner.

Siren (mythology)
In Greek mythology, the sirens (Ancient Greek: singular: ; plural: ) were humanlike beings with alluring voices; they appear in a scene in the Odyssey in which Odysseus saves his crew's lives. Roman poets placed them on some small islands called Sirenum scopuli. In some later, rationalized traditions, the literal geography of the "flowery" island of Anthemoessa, or Anthemusa, is fixed: sometimes on Cape Pelorum and at others in the islands known as the Sirenuse, near Paestum, or in Capreae. All such locations were surrounded by cliffs and rocks. Sirens continued to be used as a symbol for the dangerous temptation embodied by women regularly throughout Christian art of the medieval era. Nomenclature The etymology of the name is contested. Robert S. P. Beekes has suggested a Pre-Greek origin. Others connect the name to σειρά (''seirá'', "rope, cord") and εἴρω (''eírō'', "to tie, join, fasten"), resulting in the meaning "binder, entangler", i.e. one who binds ...

Fossil Taxa Described In 1991
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...
