Egyptian Desert Finds Shark Tomb
A research team from Cairo University successfully uncovered fossils belonging to ancient shark cemeteries buried in the Abo Tthor Territory Plateau in the Egyptian desert. These species date back to the Cretaceous period, tens of millions of years ago, when the area was covered by ocean. The discovery includes 14 teeth from five different species of extinct sharks, two of which are considered to be identified for the first time in Egypt. Additionally, the find includes the Scapanorhynchus species with needle-like teeth, believed to be the most recent in the African fossil record. Variations in tooth shapes suggest that these species inhabited different environments; some thrived in waters near the coast, while others dwelled in the deep ocean. This ancient biodiversity is attributed to a phenomenon known as “deep-water upwelling,” which is rich in nutrients and led to the development of an interconnected food chain. The accumulation of teeth in the phosphate layers represents a gradual buildup over thousands of years, narrating the story of a lost marine environment in Egypt.
