1232

Chicxulub is now the center of a new, controversial study that aims to describe a possible connection between dino-killer and magma emerging under the water.

Dinosaur killer

Chicxulub asteroid is believed to hit Mexico’s Yucatan Peninsula about 66 million years ago and destroying all the dinosaur population as a result.

This theory was supported for years: hundreds of species became extinct because of the Chicxulub asteroid.

Its crater is located near Chicxulub town and was named after it. The crater cannot be seen as it’s buried underneath the Yucatan Peninsula in Mexico.

As we’re not able to see the Chicxulub crater, you can compare it to Barringer Crater, Arizona.

Its diameter is 1.186 kilometers (0.737 mi) and the depth 170 meters (560 ft). Chicxulub crater is much bigger, it has a diameter of 150 km (93 mi) and is 20 km (12 mi) deep.

However, “…people still argue about which one was actually the primary driver of environmental changes that resulted in the death of dinosaurs,” said Leif Karlstrom.

Massive magma trigger

This time, a new theory is offered: the notorious asteroid is suggested to be the trigger of massive magma released under the ocean all around the world.

For instance, scientists suggested that perhaps the asteroid triggered Deccan Trap volcanism, leading to the extinction of Earth’s plant and animal species.

To be more accurate, dinosaurs and other animals died because of deadly gases and choking clouds of debris.

Also, as the hot magma arises between the Earth plates, the new seafloor emerged.

New seafloor emerged about 66 million years ago:

Thus, the new problem of undersea magma arises, and we need to fight with it somehow.

“That’s what we need to work on next, I would say: trying to tease out what the effects on the environment were of the volcanic activity,” Byrnes said.
