Trionyx ikoviensis is an extinct species of softshell turtles which existed in what is now Ukraine during the early Lutetian age of the Eocene epoch. [1]
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 20 genera and 30 species are now extinct. Seven of its eight surviving species are native to South America: the genus Peltocephalus, with only one species ; and the genus Podocnemis, with six living species of South American side-necked river turtles. There is also one genus native to Madagascar: Erymnochelys, the Madagascan big-headed turtle, whose single species E. madagascariensis.
Chelodina, collectively known as snake-necked turtles, is a large and diverse genus of long-necked chelid turtles with a complicated nomenclatural history. Although in the past, Macrochelodina and Macrodiremys have been considered separate genera and prior to that all the same, they are now considered subgenera of the Chelodina, further Macrochelodina and Macrodiremys are now known to apply to the same species, hence Chelydera is used for the northern snake-necked turtles.
Axestemys is an extinct genus of softshell turtle that lived from the Late Cretaceous to the Eocene in western North America and Europe.
Meiolaniidae is an extinct family of large, probably herbivorous stem-group turtles with heavily armored heads and tails known from South America and Australasia. Though once believed to be cryptodires, they are not closely related to any living species of turtle, and lie outside crown group Testudines, having diverged from them around the Middle Jurassic. They are best known from the last surviving genus, Meiolania, which lived in the rain forests of Australia from the Miocene until the Pleistocene, and insular species that lived on Lord Howe Island and New Caledonia during the Pleistocene and possibly the Holocene for the latter.
Rhinoclemmys is a genus of turtles in the family Geoemydidae, the only genus in the subfamily Rhinoclemmydinae. Member species of the genus are commonly known as the Neotropical wood turtles and are the only geoemydids known from the Americas. As such, they have adapted to a wide range of habitats, which is reflected in the species' common names.
The Fur Formation is a marine geological formation of Ypresian age which crops out in the Limfjord region of Denmark from Silstrup via Mors and Fur to Ertebølle, and can be seen in many cliffs and quarries in the area. The Diatomite Cliffs is on the Danish list of tentative candidates for World Heritage and may become a world Heritage site.
Anosteira is an extinct genus of carettochelyid turtle from the Eocene to the Oligocene of Asia and North America.
Argillochelys is an extinct genus of sea turtle from the middle to lower Eocene in what is now Britain. It was first named by Lydekker in 1889.
Eochelone is an extinct genus of sea turtle from the late Eocene. It was first named by Dollo in 1903. Its type species is E. brabantica.
Arabemys is an extinct genus of sea turtle. It was first named in 1999, and contains one species, A. crassiscutata. It is known from deposits of Late Paleocene or Early Eocene age near the village of Linah in northern Saudi Arabia.
Cosmochelys is an extinct genus of sea turtle from the Eocene of Africa. It was first named by Andrews in 1920, and contains one species, C. dolloi.
Eosphargis is an extinct genus of sea turtles from the Eocene of Africa, Europe, and North America. It was first named by Richard Lydekker in 1889, and contains one species, E. gigas. The species is also known as Anglocetus beatsoni.
Allaeochelys is an extinct genus of Carettochelyid turtle, known from the Eocene to Miocene of Europe, Asia, North America and Africa.
Duerosuchus is an extinct genus of crocodilian. Remains have been found from Corrales del Vino in Zamora, Spain, and are middle Eocene in age. Duerosuchus is known from a single skull that is incomplete but otherwise well preserved, as well as a lower jaw, some osteoderms, and possibly some vertebrae.
Puppigerus is an extinct genus of sea turtle from the Eocene. It is known from finds in the United States, the United Kingdom, Belgium, Denmark, and Uzbekistan.
Palaeoamyda is an extinct genus of softshell turtle belonging to the family Trionychidae. Remains have been found in the Eocene of Germany.
Chelodina alanrixi is a species of snake-necked fossil turtle which was described in 2001 using material gathered in Redbank Plains, Queensland, Australia. It is a member of the Chelidae Pleurodira. The fossil has been dated to the Eocene Epoch.
Pancheloniidae is a clade of sea turtles It is defined as all turtles more closely related to cheloniid sea turtles than to dermochelyid ("leatherback") sea turtles.
Tasbacka is an extinct genus of sea turtle containing several species.
Banhxeochelys is an extinct genus of Geoemydid turtles that lived during the middle to late Eocene of Vietnam. The type and only species is Banhxeochelys trani. The genus name origin is from the pancake-like Vietnamese dish bánh xèo and the Latin chelys, meaning turtle in Greek. The specific name honors Đặng Ngọc Trần, the retired director of the International Cooperation Division of the Department of Geology and Minerals of Vietnam. The fossils of Banhxeochelys were found in Na Duong coal mine of Lạng Sơn Province. The type locality of Banhxeochelys yielded more than 100 turtles, but only the 30 best-preserved specimens were described and identified as Banhxeochelys because the rest are too fragmentary or poorly preserved for useful morphological data.
