Hotly debated among scientists, the end of the dinosaurs during the Cretaceous mass extinction, gave rise to the organisms that we see today. By Gabe Allen. Sep 1, 2022 2:00 PM Jul 19, 2023 1:37 PM ...

Ever since the first dinosaur fossils were identified in the 19th century, scientists have been trying to figure out why ...

At least five times, a biological catastrophe has engulfed Earth killing off the vast majority of species. As scientists say we’re in a sixth mass extinction, what can we learn from the past?

The Cretaceous period was the last and longest segment of the Mesozoic era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic period about 145 ...

Cretaceous-Paleogene extinction - 66 million years ago. The Cretaceous-Paleogene extinction event is the most recent mass extinction and the only one definitively connected to a major asteroid impact.

The mass extinction at the end of the Cretaceous Period is perhaps the most famous in history. Over 66 million years ago, a 15-kilometer-wide asteroid struck what is now Mexico and changed life on ...

Above: an artist's reconstruction of the end-Cretaceous mass extinction event and an inset of a 3D-rendered goblin shark. These sharks are one of the most ancient of the species that are still ...

Perhaps the most well-known extinction is the Cretaceous-Paleogene (K-Pg) extinction event, which took place 66 million years ago. We all know about it because it was the event that wiped out the ...

The K-Pg extinction is the most recent of five events in Earth’s history that scientists consider mass extinctions, defined by paleontologists as events where more than 75 percent of species vanish ...

Crocodylomorphs survived both the end-Triassic mass extinction (roughly 201.4 million years ago) and the end-Cretaceous mass extinction (about 66 million years ago), which killed all non-avian ...

Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.

The mass extinction at the end of the Cretaceous Period is perhaps the most famous in history. Over 66 million years ago, a 15-kilometer-wide asteroid struck what is now Mexico and changed life on ...
