What to know about Paleontology

The article describes the paleontological research of Gaby Clark and her team at the Qreiya 3 site in Egypt. Their findings of fossil fish from approximately 62 million years ago provide evidence of how modern marine ecosystems began to recover and establish themselves following the end-Cretaceous mass extinction.

What happened

Fossil fishes buried in the desert reveal a missing chapter in marine history Gaby Clark Scientific Editor Andrew Zinin Lead Editor When an asteroid struck Earth about 66 million years ago, it ended the age of dinosaurs and transformed life across the planet.

Why it matters

The effects of that catastrophe are visible in the fossil record on land, but scientists know far less about what happened to fishes in the seas during the first few million years after the extinction.

Common ground

Like many people during the pandemic, I suddenly found myself living through long stretches of isolation and uncertainty.
