Carettochelyidae is a family of cryptodiran turtles belonging to the Trionychia. It contains only a single living species, the pig-nosed turtle native to New Guinea and Northern Australia. Stem-group carettochelyids are known from the Cretaceous of Asia, with the family being widely distributed across North America, Europe, Asia and Africa during much of the Cenozoic.
Chelidae is one of three living families of the turtle suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside Gondwana, either in the present day or as a fossil.
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 41 genera and 57 species are now extinct. Seven of its eight surviving species are native to South America: the genus Peltocephalus, with two species, only one of which is extant ; and the genus Podocnemis, with six living species of South American side-necked river turtles and four extinct. 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.
The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between 47.8 and41.2 Ma. The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch.
Bothremydidae is an extinct family of side-necked turtles (Pleurodira) known from the Cretaceous and Cenozoic. They are closely related to Podocnemididae, and are amongst the most widely distributed pleurodire groups, with their fossils having been found in Africa, India, the Middle East, Europe, North America and South America. Bothremydids were aquatic turtles with a high morphological diversity, indicative of generalist, molluscivorous, piscivorous and possibly herbivorous grazing diets, with some probably capable of suction feeding. Unlike modern pleurodires, which are exclusively freshwater, bothremydids inhabited freshwater, marine and coastal environments. Their marine habits allowed bothremydids to disperse across oceanic barriers into Europe and North America during the early Late Cretaceous (Cenomanian). The youngest records of the group are indeterminate remains from Saudi Arabia and Oman, dating to the Miocene.
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.
Cupes is a genus of beetles in the family Cupedidae. The Cupedidae are typical “reticulate” or “net-winged” beetles with incompletely sclerotized elytra that produce the characteristic reticulate appearance.
Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.
The Qasr el Sagha Formation is a geological formation located in Egypt. The formation is part of the Wadi El Hitan World Heritage Site. The Qasr el Sagha Formation overlies the Birket Qarun Formation and is overlain by the Gebel Qatrani Formation. The sandstones and shales of the formation were deposited in a deltaic to shallow marine environment. It dates to the Late Eocene.
Prochelidella is an extinct genus of Early to Late Cretaceous chelid turtles from the Bajo Barreal, Candeleros, Cerro Barcino and Portezuelo Formations of the Cañadón Asfalto, Golfo San Jorge and Neuquén Basins in Patagonia, Argentina. It includes the following species:
Lomalatachelys neuquina is an extinct genus and species of chelid turtle from Argentina. The specimen was found in the Loma de La Lata zone approximately 75 km from Neuquen City in north west Patagonia, Argentina.
The Lignites de Soissonais is a geologic formation in the Var, Marne departments of France. It preserves fossils dating back to the Ypresian stage of the Eocene period.
Aturobatis is an extinct genus of Myliobatiform ray from the Eocene epoch. It contains a single described species, A. aquensis; however, the range of variation in this species is not well understood and it is unclear whether all specimens attributed to the genus are the same species. It is also unknown to which family this genus belongs. The type locality is the Lutetian of southern France. This genus is also known from the Ypresian of the United States, the Lutetian Lisbon Formation of Alabama, and the Priabonian Samlat Formation of Dakhla, Morocco.
Dortokidae is an extinct family of freshwater pan-pleurodiran turtles, known from the Cretaceous and Paleocene of Europe. Only four species have been named, but indeterminate fossils show that they were abundant across western and eastern-central Europe during the Cretaceous. The family is only known from postcranial remains.
Sindhochelys is a genus of extinct turtle of the family Bothremydidae. It lived during the early Paleocene in what is known Sindh, Pakistan. The genus was discovered in the Khadro Formation and named in December 2021. The genus represents the first known member of its family in Pakistan. The family Bothremydidae lived from the Cenomanian of the early Cretaceous to the Miocene epoch.
Iberoccitanemys is an extinct genus of turtle from the Bothremydidae that is known from the Marnes d'Auzas Formation in France, and also the Sobrepena Formation and Villalba de la Sierra Formation in Spain.
The Sables du Castrais Formation, also known as the Molasses du Castrais, is a geologic formation of Eocene age, outcropping in the Montagne-Noire region of France.
The Aridal Formation in the Sahara Desert of southwestern Morocco is a fossil formation with rocks dating to the Lutetian - Priabonian, preserving a middle Eocene shallow coastal environment.
Osonachelus is an extinct genus of cheloniid turtle that lived in Catalonia during the Bartonian. It is a monotypic genus known from a single species, O. decorata.
