The most fascinating thing about Plesiosaurus is the fact that they looked like a combination of the characteristics of many animals. The geological indicators of fossil recovery support the theory that coastal regions were the primary location for brooding and feeding. Plesiosaurus would then move to shallower beach areas and lay eggs that would be land-bound except during tide. Early theories speculated it was possible, but more recent discoveries indicate that Plesiosaurus’ flippers could not have supported its weight for movement on land, but could have pushed the creature through shallow waters. It has been argued that Plesiosaurus could walk on land. For the majority of their life, they lived in the water but would come to shore to lay their eggs as sea turtles do. Studies show that the Plesiosaurus lived and behaved much like the present-day sea turtle. Their powerful jaws and sharp teeth may have also enabled them to consume mollusks that lived along the prehistoric shoreline. This enabled them to feed not only on fish of all sizes, but also on any other swimming creatures that were present in the ocean at the time. It is even said to have eaten mollusks that lived along the prehistoric shoreline. Since they lived in the sea they would mostly survive by taking in and consuming fish of all sizes or any other swimming animal in the ocean during that time period, due to their sharp teeth and incredibly strong jaws. The modern loch ness monster myth is always described as a plesiosaurus. Many illustrations depict plesiosaurs attacking land animals, but a plesiosaur’s flippers could not support it on land.
The plesiosaur was not really a dinosaur. That means they were twice the size of a modern horse and twice the weight of a modern hog. These reptiles were also smaller than Pliosaurs, with Plesiosaurus measuring only 15 feet long and weighing 1,000 pounds. Of course, they did well enough to be able to swim, but they weren’t as good at adapting as Pliosaurs were. One of the most intriguing Plesiosaurus facts is that these reptiles were probably not very good at swimming.
It is known from several almost complete skeletons found over the years. It was first discovered by Mary Anning in 1821. The Plesiosaurus and the Ichthyosaurus have been found in the same area of the Lias of England and Germany. Plesiosaurus was strictly a marine creature from the Sauropsida subcategory, although a study by William Conybeare made the claim that it was more of a reptile than a mammal. Plesiosaurus was an extinct marine reptile that lived between 135 million and 120 million years ago, during the Early to Middle Jurassic Period.
