Cabindachelys
''Cabindachelys'' is a genus of extinct sea turtles. The only known species is ''Cabindachelys landanensis''. Fossils A partial skull of the ''Cabindachelys'' has been found in Cabinda, Angola, by Timothy S. Myers, Michael J. Polcyn, Octávio Mateus, Diana P. Vineyard, A. O. Gonçalves, Louis L. Jacobs. Habitat ''Cabindachelys'' lived in deep subtidal indents of the shores of Cabinda, Angola. Etymology The name of ''Cabindachelys'' is a mixture of Cabinda the place where it lived and the Greek name for turtle Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked tu ....

Sea Turtle
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.

Cheloniidae
Cheloniidae is a family of typically large marine turtles that are characterised by their common traits such as, having a flat streamlined wide and rounded shell and almost paddle-like flippers for their forelimbs. They are the only sea turtles to have stronger front limbs than back limbs. The six species that make up this family are: the green sea turtle, loggerhead sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle and the Kemp's ridley sea turtle. Morphology In contrast to their earth-bound relatives, tortoises, sea turtles do not have the ability to retract their heads into their shells. Their plastron, which is the bony plate making up the underside of a turtle or tortoise's shell, is comparably more reduced from other turtle species and is connected to the top part of the shell by ligaments without a hinge separating the pectoral and abdominal plates of the plastron. Sizes among the seven species of sea turtles range from 71 to 213 cm; for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cabinda Province
Cabinda (formerly called Portuguese Congo, kg, Kabinda) is an exclave and province of Angola in Africa, a status that has been disputed by several political organizations in the territory. The capital city is also called Cabinda, known locally as ''Tchiowa'', ''Tsiowa'' or ''Kiowa''. The province is divided into four municipalities—Belize, Buco-Zau, Cabinda and Cacongo. Modern Cabinda is the result of a fusion of three kingdoms: N'Goyo, Loango and Kakongo. It has an area of and a population of 716,076 at the 2014 census; the latest official estimate (as at mid 2019) is 824,143. According to 1988 United States government statistics, the total population of the province was 147,200, with a near even split between rural and urban populations. At one point an estimated one third of Cabindans were refugees living in the Democratic Republic of the Congo; however, after the 2007 peace agreement, refugees started returning to their homes.

Nichollsemys
''Nichollsemys'' is a genus of extinct sea turtles. The only known species is ''Nichollsemys baieri''. Taxonomy Fossils of the ''Nichollsemys'' have been found in Alberta, Canada, by Donald Brinkman. The fossils found are all skulls. The name of ''Nichollsemys'' is a tribute to Elizabeth Nicholls, a paleontologist from Canada who studied marine reptiles from the Triassic period. She had previously done work with Brinkman when they found the ichthyosaur genus Pattinatator. Evolution Description The full length of the ''Nichollsemys'' is unknown, but Brinkman made a chart of the length of some parts of the specimen. The length from the basioccipital to the premaxilla measures 11.4 cm, the width of all the quadrates measures 9.8 cm, the depth at level of the quadrates measures 7.1 cm, the intraorbital width measures 2 cm, and the length measures 3.6 cm.

Allopleuron
''Allopleuron'' is a genus of extinct sea turtle, which measured long in life. The type species is ''Allopleuron hofmanni''. It is a basal member of the clade Pancheloniidae, closely related to ''Protosphargis''. Similar to ''Protosphargis'', it was characterized by shell reduction. Fossil history ''Allopleuron'' lived from the Early Cretaceous (Cenomanian age, 94.3 Ma) to the Oligocene (Rupelian age, 28.4 Ma), therefore surviving the Cretaceous-Paleogene extinction event. Fossils have been found from Germany, the Netherlands, Kazakhstan and the United States. Life history ''Allopleuron'' was believed to have used the Laurasian-Holarctic The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere.

Late Paleocene
The Thanetian is, in the International Commission on Stratigraphy, ICS Geologic timescale, the latest age (geology), age or uppermost stage (stratigraphy), stratigraphic stage of the Paleocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene). The Thanetian is sometimes referred to as the Late Paleocene. Stratigraphic definition The Thanetian was established by Switzerland, Swiss geologist Eugène Renevier in 1873. The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet. The base of the Thanetian Stage is laid at the base of magnetic chronozone C26n. The references profile (Global Boundary Stratotype Section and Point) is in the Zumaia section (43° 18'N, 2° 16'W) at the beach of Itzurun, Pais Vasco, northern ...
