Oxfordian life

Leedsichthys is an extinct genus of pachycormid fish that lived in the oceans of the Middle to Late Jurassic. It was the largest ray-finned fish, and amongst the largest fish known to have ever existed.

Kryptodrakon is an extinct genus of pterodactyloid pterosaur from the Middle to Late Jurassic with an age of approximately 162.7 million years. It is known from a single type species, Kryptodrakon progenitor. The age of its fossil remains made Kryptodrakon the basalmost and oldest pterodactyloid known to date. thumb|Life reconstruction of Kryptodrakon progenitor

Sericipterus is an extinct genus of rhamphorhynchid pterosaur. It is known from the Late Jurassic (early Oxfordian age) Shishugou Formation in Xinjiang, China.

Gallardosaurus is a genus of pliosaurid plesiosaur from the Caribbean seaway. It contains the single species Gallardosaurus iturraldei. Gallardosaurus was found in middle-late Oxfordian-age (Late Jurassic) rocks of the Jagua Formation of western Cuba. Gallardosaurus is believed to be evolutionarily connected to Peloneustes, a pliosaurid commonly found in the Oxfordian-aged sediment.

Cacibupteryx is a genus of rhamphorhynchid pterosaur from the middle-late Oxfordian-age Upper Jurassic Jagua Formation of Pinar del Río, Cuba.

Vinialesaurus is a genus of plesiosaur from the Late Jurassic (Oxfordian) Jagua Formation of Pinar del Río, Cuba. The combinatio nova of the type species is Vinialesaurus caroli, first described as the subspecies Cryptocleidus? cuervoi caroli by Ricardo De la Torre and Luis Rojas in 1949 under the holotype MNHNCu P 3008, and redescribed by Zulma Gasparini, Bardet and Iturralde in 2002. The authors of the 2002 paper considered Vinialesaurus distinct enough from Cryptocleidus to warrant its own genus, but it was a cryptoclidid.

Nesodactylus was a genus of rhamphorhynchid pterosaur from the middle-late Oxfordian age Upper Jurassic Jagua Formation of Pinar del Río, western Cuba.

left|thumb|CGI reconstruction of a gliding M. furculiferum Maiopatagium is an extinct genus of gliding euharamiyids which existed in Asia during the Jurassic period. It possessed a patagium between its limbs and presumably had similar lifestyle to living flying squirrels and colugos. The type species is Maiopatagium furculiferum, which was described from the Tiaojishan Formation by Zhe-Xi Luo in 2017; it lived in what is now the Liaoning region of China during the late Jurassic (Oxfordian age). Maiopatagium and Vilevolodon, described concurrently, offer clues to the ways various synapsids have

Proexochokefalos (meaning "big head with big tuberosities") is an extinct genus of machimosaurid teleosauroid from the Middle to Late Jurassic of France and Switzerland. In life, it was a large marine reptile that would have fed on other large animals.

Xianshou is a genus of gliding haramiyidan synapsid known from the Oxfordian stage of the Jurassic period, approximately 160 million years ago. Two species, X. linglong and X. songae, are known from fossils of the Tiaojishan Formation in the Liaoning province of China.

Batrachomimus is an extinct genus of neosuchian crocodyliform known from the Late Jurassic Pastos Bons Formation of northeastern Brazil. It contains a single species, Batrachomimus pastosbonensis, with the specific name referring to the formation, which was first described and named by Felipe C. Montefeltro, Hans C. E. Larsson, Marco A. G. de França and Max C. Langer in 2013. It is known from a nearly complete skull, osteoderms and limb bones. Batrachomimus belongs to the family Paralligatoridae and predates all other members of the family and its immediate sister group, Eusuchia, by 30 millio

Junggarsuchus () is an extinct genus of sphenosuchian crocodylomorph from the Middle or Late Jurassic period of China. The type and only species is J. sloani. The generic name of Junggarsuchus comes from the Junggar Basin (the anglicization of Dzungar), where the fossil was found, and the Greek word "souchos" meaning crocodile. The specific name, "sloani" is in honor of C. Sloan, who is credited with finding the holotype.

Liaodactylus is a genus of filter-feeding ctenochasmatid pterosaur from the Jurassic of China. The genus contains one species, L. primus, described by Zhou et al. in 2017. As an adaptation to filter-feeding, Liaodactylus had approximately 150 long, comb-like teeth packed closely together. It is both the earliest known ctenochasmatid and the first filter-feeding pterosaur from the Jurassic Yanliao Biota. Later and more specialized ctenochasmatids differ from Liaodactylus in having longer snouts, smaller openings (or fenestrae) in the skull, and more teeth. Within the Ctenochasmatidae, Liaodacty

Almadasuchus is an extinct genus of crocodylomorph known from the early Late Jurassic (early Oxfordian stage) Puesto Almada Member of the Cañadón Calcáreo Formation of Patagonia, Argentina. It contains a single species, Almadasuchus figarii. It is known from the holotype MPEF-PV 3838, a well-preserved posterior region of the skull as well as other skull and postcranial remains. Almadasuchus was recovered from Puesto Almada, 30 m above the fish beds, dated as Oxfordian in age.

Vilevolodon is an extinct, monotypic genus of volant, arboreal euharamiyids from the Oxfordian age of the Late Jurassic of China. The type species is Vilevolodon diplomylos. The genus name Vilevolodon references its gliding capabilities, Vilevol (Latin for "glider"), while don (Greek for "tooth") is a common suffix for mammalian taxon titles. The species name diplomylos refers to the dual mortar-and-pestle occlusion of upper and lower molars observed in the holotype; diplo (Greek for "double"), mylos (Greek for "grinding").

Neosteneosaurus is a genus of machimosaurid, known from the Middle Jurassic Oxford Clay of the UK, and Marnes de Dives, France.
