Scientists discovered a prehistoric shark fossil site beneath the Abu-Tartur Plateau in Egypt's Western Desert. The findings, which date back 66 million years to the late Cretaceous period, include 14 shark teeth representing seven distinct species.
Why it matters
The presence of diverse shark teeth within the Duwi Formation suggests the region was once a nutrient-rich sea during the late Cretaceous. This discovery provides crucial evidence for understanding the ancient marine ecosystems that occupied northern Africa.
Researchers identified seven shark species through an analysis of 14 fossilized teeth found in phosphate beds. The team compared these specimens against global records to determine that five of the species are extinct and three are new to Egypt.
The players
Cretaceous Research
This peer-reviewed academic journal focuses on the geology and paleontology of the Cretaceous period.
The details
Paleontologists excavated the teeth from the Duwi Formation, which has yielded significant data about the ancient environment. The study indicates that the Scapanorhynchus cf. raphiodon may have been discovered in Africa for the first time.
Timeline
The sharks inhabited the region 66 million years ago.
The study findings were published in the journal Cretaceous Research in August 2026.
The Big Picture
This discovery extends the ongoing geological mapping and biodiversity assessment of the Duwi Formation. By adding new species to the regional record, the study forces a reassessment of late Cretaceous marine migration patterns across North Africa.
While this discovery is primarily academic, it enhances our understanding of how ecosystems adapt to extreme environmental shifts over millions of years. This knowledge assists scientists in predicting how modern marine environments might react to future climate pressures.
The takeaway
This study highlights how phosphate-rich desert regions act as critical time capsules for Earth's prehistoric history. It serves as a reminder that significant biological discoveries are often hiding beneath the surfaces of arid landscapes.
What happens next
Researchers are planning future expeditions to the Abu-Tartur Plateau to search for additional fossil specimens and expand the current site inventory.
