Ancient shark teeth discoveries in Egypt reveal five extinct species

Researchers working in the Abu-Tartur Plateau region of Egypt's Western Desert have identified 14 fossilised shark teeth belonging to five distinct extinct species. The discoveries offer valuable new evidence about the diversity of ancient predators that inhabited North African waters during the Late Cretaceous period, a time when these areas were covered by warm tropical seas rather than arid desert landscape.

The teeth, carefully excavated and analysed by scientists, represent a significant addition to the existing fossil record for the region. Each specimen provides clues about the size, diet and behaviour of these ancient marine creatures that dominated ocean ecosystems millions of years before modern sharks evolved.

The findings underscore the rich paleontological heritage concealed beneath Egypt's vast desert expanses. The Abu-Tartur Plateau, now a barren landscape, was once a thriving marine environment teeming with life. Similar discoveries in the region have steadily expanded scientific understanding of how ocean ecosystems functioned during the Cretaceous era.

This research adds to growing evidence that North Africa's ancient seas supported far greater shark diversity than previously recognised. The dental morphology and size variations among the discovered teeth suggest these species occupied different ecological niches, indicating a complex and well-established marine food chain in prehistoric times. The discovery reinforces Egypt's importance as a site for understanding ancient evolutionary history.
