Pronunciation: [plɪəsˈɔːɹəs] (IPA) 
The correct spelling of "Pliosaurus" is /plaɪoʊˈsɔrəs/. The word is pronounced with a long "i" sound as in "pie," followed by the letters "o" and "u" pronounced together to make the "ou" sound as in "out." The final two syllables are pronounced with a short "o" sound and the "uh" sound, respectively. Pliosaurus is a genus of large, predatory marine reptiles that lived during the Late Jurassic period.
Pliosaurus refers to a genus of extinct marine reptiles that existed during the Jurassic period, approximately 155 to 145 million years ago. It belongs to the family of short-necked plesiosaurs known as Pliosauridae. Pliosaurus is characterized by its large size, robust body structure, and powerful jaws, making it one of the largest and most formidable predators of its time.
These reptiles typically reached lengths of around 30 to 40 feet, with some exceptionally large specimens potentially measuring up to 50 feet. Pliosaurus had a streamlined body with four powerful flippers that aided in its locomotion through the water. Its massive skull housed sharp teeth, some of which were over a foot long, enabling it to grasp and tear apart its prey.
Despite their intimidating appearance, Pliosaurus were not closely related to dinosaurs; they were reptiles that lived in the ocean while dinosaurs roamed the land. These carnivorous creatures likely preyed on a variety of marine animals, including fish, mollusks, and even other marine reptiles.
The fossil record of Pliosaurus is relatively well-documented, with numerous specimens found in different parts of the world, including Europe, North America, and South America. These fossils have provided valuable insights into the morphology, behavior, and ecological role of these mighty marine reptiles during the Jurassic era.
In conclusion, Pliosaurus was an apex predator of its time, with its massive size, strong jaws, and carnivorous diet making it a fearsome and prominent figure in the ancient marine ecosystem.
A marine reptile of the Upper Oolites, intermediate in structure between the plesiosaur and ichthyosaur.
