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).
Scientists may have finally found where the object that wiped out the dinosaurs came from.. The mass extinction event that occurred 66 million years ago – the most recent on Earth – came about ...
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 ...
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.
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]
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.
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
Last Day of the Dinosaurs is a 2010 Discovery Channel television documentary about the K-T extinction, which resulted in the extinction of the non-avian dinosaurs. [1] It portrays the Alvarez hypothesis as the cause of extinction. The documentary was released on August 28, 2010 and narrated by Bill Mondy. [2]
