Alfred Wegener tried to prove with fossil evidence that Earth's landmasses move over time. His theory of continental drift was supported by the distribution of identical fossils across various continents, suggesting that these landmasses were once connected.

The main idea of Wegener's continental drift theory is that land masses move across Earth's surface over time. He proposed that continents were once joined together and have since drifted apart to their current positions.

Cynognathus fossils were important to Wegener's theory because they were found on lands now separated by a wide ocean. This discovery supported his idea that the continents were once connected, allowing these species to inhabit those areas.
