Liaoningopterus, sometimes misspelled as "Liaoningopteryx", was a genus of anhanguerid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China.
Pachycheilosuchus is an extinct genus of neosuchian from the Early Cretaceous of Texas, United States. Previously known, in part, as the "Glen Rose form", this crocodylomorph is notable for its procoelous vertebrae, otherwise found only in derived eusuchian crocodilians, a thick margin on the maxillae, and a shield of armor on the neck formed by the fusion of six individual scutes.
Terminonatator is a genus of elasmosaurid plesiosaur from the Late Cretaceous of Saskatchewan, Canada. It is known from a skull and partial skeleton from a young adult, found in the Campanian-age Bearpaw Formation near Notukeu Creek in Ponteix. Terminonatator is currently one of the youngest plesiosaurs from the Western Interior Seaway.
Wannaganosuchus is an extinct genus of small alligatorid crocodylian. It was found in Late Paleocene-age rocks of Billings County, North Dakota, United States.
Argochampsa is an extinct genus of eusuchian crocodylomorph, usually regarded as a gavialoid crocodilian, related to modern gharials. It lived in the Paleocene of Morocco. Described by Hua and Jouve in 2004, the type species is A. krebsi, with the species named for Bernard Krebs. Argochampsa had a long narrow snout, and appears to have been marine in habits.
Rugosuchus is an extinct genus of neosuchian crocodyliform from the late Early Cretaceous of China. It is known from most of a skull, a partial postcranial skeleton, and a second partial skeleton including part of the hips. It was described by Xiao-Chun Wu and colleagues in 2001, with R. nonganensis as the type species. At the time of its description, it was the most complete crocodyliform from northeastern China, and only the second known.
Nigersaurus is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago. It was discovered in the Elrhaz Formation in an area called Gadoufaoua, in the Republic of Niger. Fossils of this dinosaur were first described in 1976, but it was only named Nigersaurus taqueti in 1999, after further and more complete remains were found and described. The genus name means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet, who discovered the first remains.
Edentosuchus is a genus of protosuchian crocodylomorph. It is known from fossils found in rocks of the Early Cretaceous-age Tugulu Group from the Junggar Basin, Xinjiang, China. Two partial skulls and several neck vertebrae are known to date. An articulated partial postcranial skeleton may also belong to this genus, but there is no overlapping material between it and known Edentosuchus specimens. Edentosuchus was described in 1973 by Yang Zhongjian, and is based on IVPP V 3236, a partial skull and associated neck vertebrae. The type species is E. tienshanensis. A joint Natural History Museum of Los Angeles County-National Geological Museum of China expedition recovered another partial skull in 2000. Yang originally assigned it to its own family (Edentosuchidae) within Protosuchia, but later research by Diego Pol and colleagues using the new material found it to be a protosuchid.
Iharkutosuchus is an extinct genus of basal eusuchian crocodyliform. Its fossils have been found in the Santonian-age Upper Cretaceous Csehbánya Formation in the Bakony Mountains of western Hungary.
Siquisiquesuchus is an extinct genus of gavialoid crocodilian. It is known from cranial remains and a few postcranial bones found in Miocene-age rocks of the Castillo Formation in northwestern Venezuela.
Aetodactylus is a genus of targaryendraconian pterosaur. It is known from a lower jaw discovered in Upper Cretaceous rocks of northeastern Texas, United States.
Pterofiltrus is a genus of ctenochasmatid pterosaur from the Early Cretaceous of western Liaoning, China.
Moganopterus is an extinct genus of ctenochasmatid pterosaur from the Early Cretaceous of western Liaoning Province, China.
Hexing is an extinct genus of basal ornithomimosaur dinosaur known from the Early Cretaceous of northeastern China. It contains a single species, Hexing qingyi.
Ikrandraco is a genus of lonchodraconid pterodactyloid pterosaur known from Lower Cretaceous rocks in northeastern China and the Cambridge Greensand of the UK. It is notable for its unusual skull, which features a crest on the lower jaw.
Convolosaurus is a genus of basal ornithopod dinosaur from the Twin Mountains Formation from Proctor Lake in Comanche County, Texas. The type and only species is Convolosaurus marri.
Ferrodraco is an extinct genus of anhanguerid pterosaur known from the Late Cretaceous Winton Formation of Queensland, Australia, containing the single species F. lentoni. The species was named after the former mayor of Winton, Graham Thomas ‘Butch’ Lenton. It is the most complete pterosaur fossil from Australia, being known from the holotype specimen AODF 876, consisting primarily of the anterior portion of the skull and dentary, cervical vertebral centra and a partial wing. Its wingspan was estimated to be about 4 meters (13 ft). Ferrodraco was found to have been within the subfamily Ornithocheirinae, as sister taxon to Mythunga. A recent study also recovered Ferrodraco as sister taxon to Mythunga, but both placed within the family Anhangueridae, more specifically within the subfamily Tropeognathinae. Ferrodraco is also the latest surviving member of Anhangueria.
Ankylorhiza is an extinct genus of toothed whale that lived in what is now the United States during the Oligocene epoch, between 29 and 23.5 million years ago. The type and only known species is A. tiedemani, though two fossil skeletons may represent an additional, second species within the genus. Ankylorhiza was about 4.8 meters (16 ft) long, with a long, robust skull bearing conical teeth that were angled forwards at the tip of the snout.
