this evidence shows that this creature inhabited both continents because it swam across the ocean.
|
|
|
this evidence shows that the two continents have similar climatic conditions
|
|
|
this evidence show that the Cynognathus could not have swum or flown such great distances, so the continents were once connected
|
|
|
this evidence shows that the Cynognathus could have flown between the continents over time
|
Detailed explanation-1: -Fossils of the Cynognathus have been discovered on both South America and Africa. How does this evidence help support the hypothesis of continental drift? This evidence shows that this creature inhabited both continents because it swam across the ocean.
Detailed explanation-2: -Cynognathus and Lystrosaurus were land reptiles and were unable to swim. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. This would indicate that the glaciers either formed in the middle of the ocean and/or covered most of the Earth.
Detailed explanation-3: -This suggests that South America and Africa were joined during the Early Permian. Cynognathus is an extinct mammal-like reptile. The name literally means ‘dog jaw’. Cynognathus was as large as a modern wolf and lived during the early to mid Triassic period (250 to 240 million years ago).
Detailed explanation-4: -To him, the presence of identical fossil species along the coastal parts of Africa and South America was the most compelling evidence that the two continents were once joined.
Detailed explanation-5: -Their fossils have been found across South America, Africa, India, and Antarctica. Wegener thought that all of these organisms must have lived side by side. The lands later moved apart so that the fossils are separated. Wegener used fossil evidence to support his continental drift hypothesis.
