Egypt's Desert Was Once an Ocean: Shark Fossils Reveal Rich Marine Life from 83 Million Years Ago

A recent scientific study reveals a pivotal piece of the distant past, confirming that the current Egyptian desert was once home to a warm and thriving marine ecosystem. The research highlights exceptional biodiversity of sharks that lived during the Cretaceous period, altering our understanding of the region's geological history.

Rare Fossil Discoveries in Phosphate Mines

A research team from Cairo University led precise excavation operations in the Abu Tartur area, where phosphate minerals have been extracted for decades. These operations uncovered hundreds of fossilized teeth, which were analyzed in detail to identify extinct shark species. These specimens represent a rare record of marine life that flourished in the region over 70 million years ago.

The discovery includes five different shark species, four of which have been recorded for the first time in the Egyptian fossil record. The species 'Scapanorhynchus raphiodon' stands out as the first official discovery in Egypt and the entire African continent. The coexistence of these species indicates ideal environmental conditions, including sufficient sunlight, moderate temperatures, and healthy levels of dissolved oxygen.

Broader Geological and Historical Context

This research project dates back to 2024, with initial results published regarding two shark species, raising the total number of species discovered at the site to seven. Scientists emphasize that the transition from ocean to desert was not a sudden event, but the result of slow climatic and geological changes spanning millions of years. The team continues to expand the scope of their search to uncover more about other organisms that shared this ancient ecosystem.

This discovery is a significant scientific achievement that transcends local boundaries, contributing to rewriting the known time periods for certain shark species on a global scale. Researchers affirm that continued exploration of the plateau may reveal more secrets hidden beneath the sands, enriching human knowledge of Earth's history and the evolution of marine life.
