Yes, the Sahara Desert used to be covered by a vast seaway.
Millions of years ago, specifically between 50 and 100 million years ago, during the Cretaceous period, a large body of water known as the Trans-Saharan Seaway existed where the Sahara Desert is now. This seaway significantly shaped the region's geology and ecosystem.
Evidence of the Trans-Saharan Seaway:
- Fossil Discoveries: Fossils of marine animals, such as fish, sharks, and marine reptiles, have been found in the Sahara Desert. These discoveries provide direct evidence of the seaway's existence.
- Geological Formations: The geological formations in the Sahara, including sedimentary rocks and specific mineral deposits, are indicative of a marine environment.
- Scientific Research: Research papers published by institutions like the American Museum of Natural History confirm the presence of the Trans-Saharan Seaway based on paleontological and geological evidence.
Impact of the Seaway:
The presence of the Trans-Saharan Seaway had a profound impact on the region:
- Climate: It influenced the climate, making the area wetter and more hospitable.
- Biodiversity: It supported a diverse marine ecosystem.
- Evolution: It played a role in the evolution and distribution of various species.
In conclusion, the Sahara Desert wasn't always a desert; a significant portion of it was once a seaway, evidenced by fossil records and geological formations.
