Allosauridae is a family of medium to large bipedal, carnivorous allosauroid neotheropod dinosaurs from the Late Jurassic. Allosauridae is a fairly old taxonomic group, having been first named by the American paleontologist Othniel Charles Marsh in 1878. Allosaurids are characterized by an astragalus with a restriction of the ascending process to the lateral part of the bone, a larger medial than lateral condyle, and a horizontal groove across the face of the condyles.Barbourofelidae
Barbourofelidae is an extinct family of carnivorans of the suborder Feliformia that lived in North America, Eurasia and Africa during the Miocene epoch (16.9—9.0 million years ago) and existed for about 7.9 million years.Brachyopterus
Brachyopterus is a genus of prehistoric eurypterid of the family Rhenopteridae. It is one of the earliest known eurypterids, having been recovered from Middle Ordovician deposits in Montgomeryshire, Wales. Though other species have been assigned to it in the past, Brachyopterus is today recognized as containing one valid species, B. stubblefieldi.Brithopus
Brithopus is an extinct genus of dinocephalian therapsids. It contains a single species, Brithopus priscus, known from fragmentary remains found in the Copper
Sandstones near Isheevo, Russia.Carditidae
Carditidae is a family of marine bivalve clams of the order Carditida, which was long included in the Venerida. They are the type taxon of the superfamily Carditoidea.
Carditidae is a neglected and poorly classified family. It has six subfamilies recognised by the World Register of Marine Species, but the WoRMS has refrained from assigning contents to any family due to ambiguity and overlap in their definitions. Additionally, several genera have been or are still considered subgenera of other genera by some authors.Dyoplosaurus
Dyoplosaurus (meaning "double-armored lizard") is an extinct genus of ankylosaurid dinosaurs within the subfamily Ankylosaurinae. It is known from the lower levels of the Late Cretaceous Dinosaur Park Formation (latest middle Campanian stage, about 76.5 Ma ago) of Alberta, Canada. It contains a single species, Dyoplosaurus acutosquameus.Guaibasauridae
Guaibasauridae is a family of basal saurischian dinosaurs, known from fossil remains of late Triassic period formations in Brazil and Argentina.Ikanogavialis
Ikanogavialis is an extinct genus of gryposuchine gavialoid crocodilian. Fossils have been found in the Urumaco Formation in Urumaco, Venezuela and the Solimões Formation of Brazil. The strata from which remains are found are late Miocene in age, rather than Pliocene as was once thought. A possible member of this genus survived into the Late Holocene in the Solomon Islands.Matapanui
Matapanui is a genus of eomysticetid baleen whale from the Late Oligocene (early Chattian) Kokoamu Greensand of New Zealand.Meiolaniidae
Meiolaniidae is an extinct family of large, possibly herbivorous turtles with heavily armored heads and tails known from South America and most of Oceania. 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 relict populations that lived on Lord Howe Island and New Caledonia until 2000 years ago. A similar form is also known from the Miocene Saint Bathans Fauna of New Zealand.The family was once thought to have originated in Australia sometime in the Miocene, when the earliest Meiolania first appeared. However, due to the discovery of South American meiolaniids, including Niolamia in Eocene Argentina, it is now believed that the meiolaniids appeared sometime prior to the breakup of Gondwana during the Cretaceous. Though once believed to be cryptodires, meiolaniids are outside the Testudines crown-group, potentially indicating that their origin is even further back. Several basal non-testudine turtles possibly related to meiolaniids are known in both Laurasian and Gondwanan landmasses in the Cretaceous, such as the Asian Mongolochelys.More recently, Eocene Australian species have also been uncovered.Minmi paravertebra
Minmi is a genus of small herbivorous ankylosaurian dinosaur that lived during the early Cretaceous Period of Australia, about 119 to 113 million years ago.Nanshiungosaurus
Nanshiungosaurus is a genus of therizinosaurian theropod dinosaur from the Cretaceous of China.
Two species have been named in the genus: the type species Nanshiungosaurus brevispinus and Nanshiungosaurus bohlini.Neimongosaurus
Neimongosaurus ("Nei Mongol lizard") is a genus of herbivorous therizinosaur theropod dinosaur known from the Upper Cretaceous of Nei Mongol, China.
Neimongosaurus is a therizinosauroid which is known from the holotype LH V0001, a partially preserved skull and skeleton, consisting of a partial braincase, the front of the right lower jaw, a nearly complete axial column, a furcula, the shoulder girdle, both humeri, a left radius, parts of the pelvis and parts of the hindlimbs. The specimen was in 1999 collected in the Sanhangobi in Inner Mongolia from the Iren Dabasu Formation dating from the Santonian stage about 85 million years ago. A second specimen, LH V0008, consisting of a sacrum with ilia, was assigned as the paratype.The type species, Neimongosaurus yangi, was formally named and described by Zhang Xiaohong, Xu Xing, Paul Sereno, Kwang Xuewen and Tan Lin in 2001. The generic name is derived from Nei Mongol, the Chinese name for Inner Mongolia. The specific name honours Yang Zhongjian.Neimongosaurus was bipedal. The teeth in its deep lower jaw, coarsely serrated, indicate an herbivorous diet. It had elongated cervical vertebrae. Its scapula had a tapering end. Neimongosaurus is thought to have been about 2.3 meters in length.
The original describers of the genus assigned Neimongosaurus to the Therizinosauroidea, in a basal position. Subsequent cladistic analyses have indicated a position in the more derived Therizinosauridae, but an analysis in 2010 by Lindsay Zanno confirmed the original placement.Pangshura
Pangshura is a genus of geoemydid turtles endemic to South Asia. Its member species were formerly in the obsolete genus Kachuga. A fifth member, Pangshura tatrotia, was described in 2010, but it is only known from Pliocene fossils.Parksosauridae
Parksosauridae is a clade or family of small ornithischians which have previously been generally allied to hypsilophodontids. Parksosauridae is often considered a synonym of Thescelosauridae, but the two groups cannot be synonyms because Parksosauridae is defined as a stem, while Thescelosauridae is defined as a node.Rioarribasuchus
Rioarribasuchus is a genus of aetosaur. Fossils have been found from the Chinle Formation in Arizona and New Mexico that date back to the upper Late Carnian stage of the Late Triassic.Therizinosaurus
Therizinosaurus (; 'scythe lizard', from Ancient Greek θερίζω, meaning 'to reap', and σαῦρος, meaning 'lizard') is a genus of very large theropod dinosaurs. Therizinosaurus comprises the single species T. cheloniformis, which lived in the late Cretaceous Period (early Maastrichtian stage, around 70 million years ago), and was one of the last and largest representatives of its unique group, the Therizinosauria. Fossils of this species were first discovered in Mongolia and were originally thought to belong to a turtle-like reptile (hence the species name, T. cheloniformis – "turtle-formed"). It is known only from a few bones, including gigantic hand claws, from which it gets its name.Vectocleidus
Vectocleidus is an extinct genus of leptocleidid plesiosaurian known from the Early Cretaceous Vectis Formation (late Barremian stage) of Isle of Wight, in the United Kingdom. It contains a single species, Vectocleidus pastorum.Zhejiangosaurus
Zhejiangosaurus (meaning "Zhejiang lizard") is an extinct genus of nodosaurid dinosaur from the Upper Cretaceous (Cenomanian stage) of Zhejiang, eastern China. It was first named by a group of Chinese authors Lü Junchang, Jin Xingsheng, Sheng Yiming and Li Yihong in 2007 and the type species is Zhejiangosaurus lishuiensis ("from Lishui", where the fossil was found). It has no diagnostic features, and thus is a nomen dubium.
