Desert Shark Graveyard Reveals Egypt's Ancient Sea
Scientists uncovered fossilized teeth from seven shark species at Egypt's Abu-Tartur Plateau in the Western Desert dating to the Late Cretaceous. The finds—including Africa’s first Scapanorhynchus raphiodon and other sharks not previously recorded in Egypt—suggest the region was once a warm, oxygen-rich sea with a thriving marine ecosystem; researchers caution the assemblage could reflect sediment mixing over time and plan further fieldwork to map the ancient coastline and environment.
