Liopleurodon (/ ˌ l aɪ oʊ ˈ p l ʊər ə d ɒ n /; meaning 'smooth-sided teeth') is an extinct genus of carnivorous pliosaurid pliosaurs that lived from the Callovian stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic period (c. 166 to 155 mya).
Liopleurodon ferox. Pliosauroidea was named by Welles in 1943. It is adapted from the name of the genus Pliosaurus, which is derived from the Greek πλειων (pleion), meaning "more/closely", and σαυρος (sauros) meaning "lizard"; it therefore means "more saurian".
[34]: 249–251 [35] The large, powerful pliosaurid Liopleurodon ferox appears to have been adapted to take on large prey, including other marine reptiles and large fish. [34]: 242–243, 249–251 The long-snouted Eardasaurus powelli like Liopleurodon also has teeth with cutting edges and may have also taken large prey. [5]
Pliosauridae is a family of plesiosaurian marine reptiles from the Latest Triassic to the early Late Cretaceous (Rhaetian to Turonian stages). The family is more inclusive than the archetypal short-necked large headed species that are placed in the subclade Thalassophonea, with early, primitive forms resembling other plesiosaurs with long necks.
In naming the specimen, Carpenter noted "Of all known pliosauroids, Plesiopleurodon wellesi most closely resembles Liopleurodon ferox from the Oxfordian of Europe, hence the generic reference." [2] It was initially described as a pliosauroid due to it short neck, a common trait of the superfamily (although it is in the order Plesiosauria).
The skull of a pliosaur, a prehistoric sea monster, was discovered on a beach in Dorset, England, and it could reveal secrets about these awe-inspiring creatures.
