The fossil above is Mesosaurus. (El fósil de arriba es Mesosaurus). Hence the correct option is c.
The fossil identified above is Mesosaurus. Mesosaurus is an extinct genus of aquatic reptile that lived during the Early Permian period, approximately 299 to 270 million years ago. It is notable for its distinctive characteristics, such as a long, streamlined body and paddle-like limbs, suggesting adaptations for an aquatic lifestyle. Mesosaurus fossils have been found in South America and Africa, particularly in Brazil and Namibia.
The presence of Mesosaurus fossils on opposite sides of the South Atlantic Ocean played a significant role in supporting the theory of continental drift and the concept of Pangaea, as the similar fossils found in geographically separated areas indicated a past connection between these continents. The Mesosaurus fossil contributes valuable information to the understanding of prehistoric marine ecosystems and the Earth's geological history. Hence the correct option is c.
