Syllomus is an extinct genus of sea turtle from the Miocene-age deposits in the US Eastern Seaboard and Egypt.
Two species are known, Syllomus aegyptiacus (Lydekker, 1889) and S. crispatus Cope, 1896. [1] [2] [3] [4] Lapparent de Broin (2001) considers Trachyaspis a possible senior synonym of Syllomus. [5]
Chelidae is one of three living families of the turtle/tortoise 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.
Richard Lydekker was an English naturalist, geologist and writer of numerous books on natural history.
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 Snakeneck Turtles.
Bothremydidae is an extinct family of side-necked turtles. They belong to suborder Pleurodira and the order Testudines. Like their modern relatives, bothremydidids often inhabited freshwater habitats, but several species were instead marine; they are unrelated to modern sea turtles. They were actively mobile omnivores. They became extinct in the Oligocene or Miocene.
Hesperotestudo is an extinct genus of tortoise that lived from the Miocene to the Pleistocene. Its remains are known from North America, Central America and Bermuda. Further specimens identifiable only to genus have been found in El Salvador.
Psephophorus is an extinct genus of sea turtle that lived from the Oligocene to the Pliocene. Its remains have been found in Europe, Africa, North America, and New Zealand. It was first named by Hermann von Meyer in 1847, and contains seven species, P. polygonus, P. calvertensis, P. eocaenus, P. oregonesis, P. californiensis, P. rupeliensis, P. scaldii, and a species discovered in 1995, P. terrypratchetti.
Toxochelys is an extinct genus of marine turtle from the Late Cretaceous period. It is the most commonly found fossilized turtle species in the Smoky Hill Chalk, in western Kansas.
Bouliachelys is an extinct genus of sea turtle from Cretaceous Australia. Its parent taxon is the clade Dermochelyoidae.
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.
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:
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.
The Oulad Abdoun Basin is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate. It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Cenomanian-Turonian) to the Eocene epoch (Ypresian), a period of about 25 million years.
Yaminuechelys is an extinct genus of chelid turtle from Argentina and the Dorotea Formation of Chile. The genus first appeared during the Late Cretaceous, and then becomes extinct during the Late Paleocene.
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 Nuequen City in north west Patagonia, Argentina.
Megalochelys is an extinct genus of cryptodiran tortoises that lived from the Miocene to Pleistocene, across Asia and possibly Eastern Europe. They are noted for their giant size, which is among the largest of any known testudine, with a maximum carapace length over 2 m in M. atlas.
Hydropelta is a genus of late Jurassic turtle from marine deposits in the Jura Mountains of eastern France.
Helochelydra is an extinct genus of extinct stem turtle known from the Early Cretaceous (Barremian) of the Isle of Wight, southern England.
Solemys is an extinct genus of stem turtle known from the Late Cretaceous of southern France and eastern Spain.
Bairdemys is an extinct genus of side-necked turtles in the family Podocnemididae. The genus existed from the Late Oligocene to Late Miocene and its fossils have been found in South Carolina, Puerto Rico, Panama and Venezuela. The genus was described in 2002 by Gaffney & Wood and the type species is B. hartsteini.
Arenila is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Western Desert of Egypt. The genus consists solely of type species A. krebsi.
