Definition
-
Plesiosauri refers to a group of prehistoric marine reptiles that lived during the Mesozoic Era, specifically the Jurassic and Cretaceous periods. They belong to the taxonomic order Plesiosauria and are characterized by their unique physical features. The name "plesiosauri" is derived from the Greek words "plesios" meaning "near" and "saurus" meaning "lizard," which describes their resemblance to both aquatic and reptilian creatures.
These marine reptiles were generally large in size, ranging from a few meters to over ten meters in length. They had a distinct body structure characterized by a broad and sturdy torso, a relatively short tail, and four long flippers. The flippers were used for propulsion and steering in water, suggesting an adaptation for a fully aquatic lifestyle.
Plesiosauri possessed a long neck with numerous vertebrae, allowing them to move their heads and necks in various directions, which likely aided in hunting prey. They had sharp conical teeth, indicating their carnivorous diet and proficiency as predators.
Fossils of plesiosauri have been found on almost every continent, suggesting a global distribution during their existence. They likely inhabited both coastal and open ocean environments, where they would have preyed upon fish, squid, and other marine organisms.
Extensive research and examination of plesiosauri fossils have helped scientists understand the diversity within this group and their evolutionary relationships with other reptiles. The study of plesiosauri plays a crucial role in unraveling the mysteries of ancient marine ecosystems and contributes to our understanding of the Earth's natural history.
