Vinctifer is an extinct genus of prehistoric bony fish erected by David Starr Jordan in 1919.
This genus is known in the fossil record from the Late Jurassic (Kimmeridgian) to the Aptian stage of the Early Cretaceous epoch (age range: from 150.8 to 109.0 million years ago.). [1] Fossils within this genus have been found in the Marizal, Romualdo and Missão Velha Formations of Brazil, Tlayua Formation of Mexico, Apón Formation of Venezuela and Nordenskjöld Formation of Antarctica.

Three species have been described: [4]
Liopleurodon is an extinct genus of large, carnivorous marine reptile belonging to the Thalassophonea, a clade of short-necked pliosaurid plesiosaurs. Liopleurodon lived from the Callovian Stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic Period. It was the apex predator of the Middle to Late Jurassic seas that covered Europe. The largest species, L. ferox, is estimated to have grown to 6.4 metres (21 ft) in length based on a large skull.
Aspidorhynchus is an extinct genus of predatory ray-finned fish from the Middle Jurassic to the earliest Cretaceous. Fossils have been found in Europe, Antarctica and the Caribbean.
Ichthyodectiformes is an extinct order of marine stem-teleost ray-finned fish. The order is named after the genus Ichthyodectes, established by Edward Drinker Cope in 1870. Ichthyodectiforms are usually considered to be some of the closest relatives of the teleost crown group.
Belonostomus is a genus of prehistoric ray-finned fish that was described by Louis Agassiz in 1844. It is a member of the order Aspidorhynchiformes, a group of fish known for their distinctive elongated rostrums.
Aspidorhynchiformes is an extinct order of ray-finned fish. It contains only a single family, the Aspidorhynchidae. Members of the group are noted for their elongated, conical rostrums, of varying length, formed from fused premaxillae. The range of the group extends from the Middle Jurassic to the late Paleocene.
Araripichthys is an extinct genus of marine ray-finned fish that lived from the Aptian to Coniacian stages of the Cretaceous period. The genus is named after the Araripe Basin, where it was found in the Crato and Santana Formations. Other fossils of the genus have been found at Goulmima in Morocco, the Tlayua Formation of Mexico and the Apón Formation of Venezuela.
Anaethalion is an extinct genus of prehistoric marine and freshwater ray-finned fish related to modern tarpons and ladyfish. It is known from the Late Jurassic to the Early Cretaceous of Europe and northeasterrn Asia, roughly encompassing the Tethys Ocean.
Pleuropholis is an extinct genus of prehistoric ray-finned fish.
Notoemys is an extinct genus of platychelyid turtle known from the Late Jurassic and Early Cretaceous of the Americas.
Bullichthys is an extinct genus of marine albuliform fish which existed in the Romualdo Formation, Brazil during the Early Cretaceous (Albian) period. The type species is B. santanensis. The genus name references its inflated otic bulla.
Torvoneustes is an extinct genus of metriorhynchid thalattosuchian. It is known from skull and postcranial remains found in the Kimmeridge Clay Formation of Dorset and Wiltshire, England, the Virgula Marls of Switzerland and also from Oaxaca, Mexico . The holotype skull of the type species was initially assigned to the species Metriorhynchus superciliosus. Postcranial remains were later discovered from the same quarry as the skull, and then these specimens were recognised as belonging to a new species of Dakosaurus, as D. carpenteri. The species was named to honour Simon Carpenter, an amateur geologist from Frome in Somerset, who discovered the fossils.
Callipurbeckia is an extinct genus of marine semionotiform ray-finned fish from the Late Jurassic and Early Cretaceous periods. Fossils have been found in Germany, Tanzania, and England.
Maledictosuchus is an extinct genus of marine crocodyliform belonging to the family Metriorhynchidae. It is the most basal member of the Rhacheosaurini Tribe with a relatively short body length, measuring 2.95 m (9.7 ft) based on the type specimen.
The La Caja Formation is a geologic formation in Mexico. It preserves fossils dating from the Kimmeridgian to the lower Berriasian. La Caja Formation is widespread in northeastern and central Mexico and known for their abundant and diverse well-preserved ammonites. It was deposited in hemipelagic conditions, and predominantly consists of siliclastic sediments, including marl, with limestone. It is laterally equivalent to the La Casita Formation, which represent more proximal facies. The ichthyosaurs Ophthalmosaurus icenicus and Parrassaurus yacahuitztli, metriorhynchid Cricosaurus saltillensis and the giant pliosaur "Monster of Aramberri" are known from the formation.
The La Casita Formation is a geologic formation in Mexico. It preserves fossils dating back to the Kimmeridgian to lowermost Berriasian. It is laterally equivalent to the La Caja Formation and the Pimienta Formation. The ichthyosaurs Jabalisaurus and Acuetzpalin are known from the formation, as well as the metriorhynchid Dakosaurus and indeterminate pliosaurs.
This list of fossil fishes described in 2019 is a list of new taxa of jawless vertebrates, placoderms, acanthodians, fossil cartilaginous fishes, bony fishes, and other fishes of every kind that were described during the year 2019, as well as other significant discoveries and events related to paleoichthyology that occurred in 2019.
Acuetzpalin is an extinct genus of platypterygiine ophthalmosaurid ichthyosaur found in the Kimmeridgian La Casita Formation in Mexico. It is known from a partial skeleton, of which the skull is surprisingly well preserved. Its length is estimated to have been more than 3.1 metres (10 ft) long, considering the missing parts of the holotype. It was the first ichthyosaur described in 2020 and the first new ichthyosaur genus described since 2017.
Platychelyidae is an extinct family of pan-pleurodiran turtles, known from the Late Jurassic and Early Cretaceous of Europe, South America, North America, and the Caribbean. It represents the oldest known clade of stem-pleurodires. All known members have been found in marine or coastal deposits. Despite this, their limb morphology suggests that they were not adapted for open marine conditions, but were likely inhabitants of shallow water environments, including brackish and saline waters, and they likely never inhabited environments more marine than lagoons. Their tolerance for saline environments likely aided their dispersal during the breakup of Pangea. Unlike modern pleurodires, which retract their necks to the sides, Platychelys retracted its neck inwards, similar to modern cryptodire turtles. Platychelys is strongly morphologically similar to mata mata and snapping turtles, suggesting that it had a similar ecology as a ram or suction feeder.
Nhanulepisosteus is an extinct genus of gar known from the Late Jurassic of Oaxaca, Mexico. It contains a single species, N. mexicanus. It is the oldest species of true gar known from fossil remains.
The Tenejapa-Lacandón Formation is a geological formation and lagerstätte in southern Mexico and western Guatemala. It preserves fossils dating to the Early Paleocene.
