The Cynognathus reptile was a dinosaur that existed 225 million years ago. It is believed that this dinosaur could NOT swim. How does the presence of the Cynognathus fossils in South America and Africa support the hypothesis of continental drift and Pangea?
Continents must have once been all connected and then when they moved apart the reptile got stuck on two different continents
