Earth scientists are slowly closing in on the class of impactor that caused the Cretaceous-Paleogene extinction event.

Tunas did not become large, fast and warm-blooded simply because an asteroid cleared the oceans of competing predators. Their defining traits appeared separately over tens of millions of years, ...

Yale University ecologists reveal a lizard lineage that rode out the dinosaur-killing asteroid event with unexpected evolutionary survival traits. Night lizards (family Xantusiidae) survived the ...

The Cretaceous–Paleogene (K–Pg) mass extinction event, marking the boundary between the Cretaceous and Paleogene periods approximately 66 million years ago, stands as one of the most profound ...

The international team reached the conclusion after analysing nickel isotopes preserved in a thin layer of clay left behind ...

A new study published in Biology Letters by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed ...

The asteroid that led to the extinction of the dinosaurs 66 million years ago probably came from the outer solar system. Geoscientists from the University of Cologne have led an international study to ...

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact ...
