Most of the suevites were resedimented soon after the impact by the resurgence of oceanic water into the crater. This gave rise to a layer of suevite extending from the inner part of the crater out as far as the outer rim. [57] Impact melt rocks are thought to fill the central part of the crater, with a maximum thickness of 3 kilometers (1.9 mi).
In that incident, about 60 per cent of the Earth’s species including all of its non-avian dinosaurs were wiped out. Researchers believe that it led to a horrific period in the planet’s history ...
A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...

Paleotsunamis are evidenced by modern technology and scientific research. One of the largest was a megatsunami resulting from the asteroid that wiped out the dinosaurs. [2] Studying paleotsunamis is an emerging science to identify and interpret paleotsunami deposits. [3]
Ammonites were affected substantially by the Triassic-Jurassic extinction and were nearly wiped out. [25] Ceratitidans , the most prominent group of ammonites in the Triassic, became extinct at the end of the Rhaetian after having their diversity reduced significantly in the Norian , while other ammonite groups such as the Ammonitina ...
After the asteroid that wiped out the dinosaurs hit what is now the Yucatan Peninsula more than 30 million years before these asteroids, its explosive energy resulted in irreversible climate change.
The extinction event produced major changes in Paleogene insect communities. Many groups of ants were present in the Cretaceous, but in the Eocene ants became dominant and diverse, with larger colonies. Butterflies diversified as well, perhaps to take the place of leaf-eating insects wiped out by the extinction.
