The world used to be very different. It used to be covered in water, allowing animals to swim to different continents. Either the animal died and sunk, or was stranded by the reducing waters and died that way. :)
Mesosaurus fossils found in both South America and Africa suggest that these continents were once connected. Mesosaurus was a freshwater reptile, incapable of crossing vast oceans, which implies the existence of a single landmass – Pangaea – where the species lived and later separated due to continental drift.

The fossil that was found on different continents and used to support the theory of continental drift is the Mesosaurus. This extinct freshwater reptile had limited swimming abilities, making it unlikely that it could have crossed vast oceans. Its distribution on both sides of the Atlantic Ocean provided evidence of land connections that later formed the basis for the theory of continental drift.
Fossil and genetic evidence strongly support the idea that modern humans originated in Africa around 200,000 years ago and migrated out of Africa to populate the rest of the world. This is known as the "Out of Africa" theory, which is supported by both fossil records and genetic studies.
I believe his first observation was the way the continents of South America and Africa "fit" together like a jigsaw puzzle (although he was not the first to realize this). He also made note of fossil discoveries in Africa which corresponded to those in South America. Finally, he began his own research which actually alligned rock formation/componants from one side of the Atlantic with the other.
Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents.
The similarity of the geological formations, such as the Appalachian Mountains in North America and the Caledonian Mountains in Scotland, suggests a connection between continents, supporting the hypothesis that Africa and South America were once joined. Additionally, fossils of the reptile Mesosaurus have been found in both Brazil and South Africa, indicating that these continents were once part of a larger landmass, as this freshwater species could not have crossed the Atlantic Ocean. Together, these geological and fossil records provide compelling evidence for the theory of continental drift.
a dinosaurs fossil is alot bigger than a retile's
a tuatara, maybe? :)

titanaboa belongs in the fossil age, they once existed and belong to the reptile race; crocodiles / alligators and boa are from the same period and are the last of its kind, aside from creatures of the deep
The fossil of Mesosaurus, a small aquatic reptile, was found in both South America and Africa. Its presence on different continents was used as evidence to support the theory of continental drift, as it suggested that the continents were once connected and later drifted apart.
