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 ...
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).
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.
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 ...
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.
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]
Whether volcanic activity played a major role in the dinosaur extinction remains up for debate, but the German researchers did find evidence to rule out that the impactor could have been an icy comet.
In the parallel universe of this novel, Earth was not struck by an asteroid 65 million years before the present. Consequently, the Cretaceous–Paleogene extinction event which wiped out the dinosaurs and other related reptiles never happened, leaving the way clear for an intelligent species to eventually evolve from mosasaurs, a family of Late Cretaceous marine lizards closely related to the ...
