Jurassic Cuba

Cryptoclidus ( ) is a genus of plesiosaur reptile from the Middle Jurassic period of England, France, and Cuba.

Geosaurus is an extinct genus of marine crocodyliform within the family Metriorhynchidae, that lived during the Late Jurassic and the Early Cretaceous. Geosaurus was a carnivore that spent much, if not all, its life out at sea. No Geosaurus eggs or nests have been discovered, so little is known of the reptile's lifecycle, unlike other large marine reptiles of the Mesozoic, such as plesiosaurs or ichthyosaurs which are known to give birth to live young out at sea. Where Geosaurus mated, whether on land or at sea, is currently unknown. The name Geosaurus means "Mother of Giants lizard", and is d

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.

thumb|Life reconstruction of C. albersdoerferi Cricosaurus is an extinct genus of marine crocodyliforms of the Late Jurassic. belonging to the family Metriorhynchidae. The genus was established by Johann Andreas Wagner in 1858 for three skulls from the Tithonian (Late Jurassic) of Germany. The name Cricosaurus means "Ring lizard", and is derived from the Greek '- ("ring") and -' ("lizard"). It was a relatively small reptile, with C. suevicus and C. araucanensis measuring and in total body length, respectively.

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

Berriasella is a discoidal evolute perisphinctacean ammonite, and type genus for the neocomitid subfamily Berriasellinae. Its ribbing is distinct, consisting of both simple and bifurcated ribs that extend from the umbilical seam across the venter; its whorl section generally compressed, the venter more or less narrowly rounded. The species Berriasella jacobi traditionally has been regarded an index fossil defining the base of the Cretaceous, however since 2016 this had been replaced by the first occurrence of Calpionella alpina. Some authors regard B. jacobi as instead belonging to the genus S
