Recent fossil discoveries at Qreiya 3 in Egypt provide critical insights into marine life shortly after the dinosaur extinction event 66 million years ago. The research reveals a rich fish community that emerged just 4 million years after the asteroid impact, highlighting early relatives of modern fish species and the ecological shifts that followed.
- 01The fossil site at Qreiya 3, Egypt, dates back to approximately 4 million years after the asteroid impact that ended the age of dinosaurs.
- 02The research team, led by Hesham Sallam, uncovered nearly 500 fossil specimens, including early relatives of tunas, jacks, and moonfishes.
- 03Findings indicate that several modern fish groups were already established shortly after the mass extinction, revealing a rapid ecological recovery.
- 04The absence of many Cretaceous-era fish lineages at the site suggests they went extinct during the end-Cretaceous event.
- 05The research was conducted by a team from the University of Michigan and supported by a National Geographic grant.

The discovery of fossils at Qreiya 3 in Egypt has shed light on marine life during the critical period following the extinction of dinosaurs approximately 66 million years ago. A research team, led by Hesham Sallam, embarked on expeditions to this remote site, uncovering nearly 500 fossil specimens that include early relatives of modern fish species such as tunas and moonfishes. These findings suggest that a diverse fish community began to re-establish itself just 4 million years after the catastrophic asteroid impact. The research highlights that while some modern fish groups were already present, many Cretaceous-era lineages were notably absent, indicating a significant ecological shift. The painstaking process of preparing and studying these fossils has provided valuable insights into how marine ecosystems evolved in the aftermath of one of Earth’s greatest mass extinctions. This work represents a significant contribution to our understanding of marine history and the resilience of life.
