Mesosaurus

Description

Mesosaurus closely resembled a three-foot long crocodile, was among the first reptiles to return to the water.  It dates backs over 250 million years ago to the Permian Period, a time when South America and Africa were joined together.  Mesosaurus skeletons have been found in both of these continents, which confirms the theory of continental drift, for it shows that the two continents broke apart and separated the region where Mesosaurus lived.  Village Silversmith’s Mesosaurus skeletons were found in Brazil.  Severe volcanic activity at the end of the Permian Period caused the greatest mass extinction of all time, which killed about 95% of species on Earth and set the stage for the age of dinosaurs.
