Un „cimitir” de rechini preistorici a fost descoperit în deșertul din Egipt: Aici era cândva o mare tropicală plină de viață

Paleontologists discovered shark teeth from at least seven extinct species on the Abu-Tartur Plateau, revealing a once-thriving marine ecosystem in ancient Egypt. This area, now a desert, was once covered by a nutrient-rich tropical sea during the Cretaceous period. The findings indicate a diverse marine life, supported by upwelling currents that brought nutrients to the surface, fostering a productive environment. The identified species include new records for Egypt, suggesting ecological niches rather than direct competition among sharks. These discoveries highlight the region's rich prehistoric biodiversity, now buried under desert sands.
