Dermochelys
The leatherback sea turtle (''Dermochelys coriacea''), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to and weights of . It is the only living species in the genus ''Dermochelys'' and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Taxonomy and evolution Taxonomy ''Dermochelys coriacea'' is the only species in genus ''Dermochelys''. The genus, in turn, contains the only extant member of the family Dermochelyidae. Domenico Agostino Vandelli named the species first in 1761 as ''Testudo coriacea'' after an animal captured at Ostia and donated to the University of Padua by Pope Clement XIII. In 1816, French zoologist Henri Blainville coined the term ''Dermochelys''. The leatherback ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelonioidea
Sea turtles (superfamily Chelonioidea), sometimes called marine turtles, are reptiles of the order Testudines and of the suborder Cryptodira. The seven existing species of sea turtles are the flatback, green, hawksbill, leatherback, loggerhead, Kemp's ridley, and olive ridley sea turtles. All six of the sea turtle species present in US waters (all of those listed above except the flatback) are listed as endangered and/or threatened under the Endangered Species Act. The seventh sea turtle species is the flatback, which exists in the waters of Australia, Papua New Guinea and Indonesia. Sea turtles can be separated into the categories of hard-shelled (cheloniid) and leathery-shelled ( dermochelyid).Wyneken, J. 2001. The Anatomy of Sea Turtles. U.S Department of Commerce NOAA Technical Memorandum NMFS-SEFSC-470, 1-172 pp. There is only one dermochelyid species which is the leatherback sea turtle.

Corsochelys
''Corsochelys'' is an extinct genus of sea turtle that lived in the Late Cretaceous (Campanian). Zangerl (1960) named the type species (and currently only species; ''C. haliniches''), based upon remains found in Alabama within the Mooreville Chalk Formation (the lower part of the Selma Group).Hiryana R. 1997. Distribution and diversity of Cretaceous chelonioids. In: ''Ancient Marine Reptiles'' (eds.) Callaway JM, Nicholls EL. Academic Press. pp. 225-241. Description ''Corsochelys'' is a basal dermochelyid. As with other basal chelonioids (such as '' Santanachelys'' and ''Toxochelys''), ''Corsochelys'' possesses a large foramen interorbitale with a narrow processus inferior parietalis, which indicates that the genus possessed salt-excreting lachrymal glands.Hiryana R. 1998.

Protostegidae
Protostegidae is a family of extinct marine turtles that lived during the Cretaceous period. The family includes some of the largest sea turtles that ever existed. The largest, '' Archelon'', had a head long. Like most sea turtles, they had flattened bodies and flippers for front appendages; protostegids had minimal shells like leatherback turtles of modern times. Anatomy As some of the first marine turtles, the protostegids set the general body plan for future species of sea turtles. They had a generally depressed turtle body plan, complete with four limbs, a short tail, and a large head at the end of a relatively short neck. Like other sea turtles, they possessed oar-like front appendages especially evolved for swimming in the open ocean. Similar to the still- extant, possibly closely related Dermochelyidae, protostegids possessed extremely reduced carapaces. Some specimens had skeletal protrusions from their ribs almost wrapping around their bodies in place of a complet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
