Ancient life signs under dinosaur-killing Chicxulub crater
Researchers have found evidence for an ancient microbial ecosystem in a hydrothermal system beneath Mexico’s Chicxulub Crater, thought to be the site of the impact that killed the dinosaurs 66 million years ago.

New study says dinosaur-dooming asteroid struck Earth at ‘deadliest possible’ angle
“For the dinosaurs, the worst-case scenario is exactly what happened … because it put more hazardous debris into the upper atmosphere and scattered it everywhere, the very thing that led to a nuclear winter.” Source: https://earthsky.org/earth/dinosaur-killing-asteroid-struck-earth-deadliest-angle…
Supercomputer Simulates the Impact of the Asteroid That Wiped Out Dinosaurs
An anonymous reader quotes a report from ZDNet: Some 66 million years ago, an asteroid hit the Earth on the eastern coast of modern Mexico, resulting in up to three quarters of plant and animal species living on the planet going extinct — including the dinosaurs. Now, a team of researchers equipped with a supercomputer have managed to simulate the entire…
Asteroid that killed the dinosaurs hit just right for maximum damage
The asteroid impact that formed Chicxulub crater and is linked to the extinction of the dinosaurs seems to have come in at the optimal angle to cause as much destruction as possible Source: https://www.newscientist.com/article/2244354-asteroid-that-killed-the-dinosaurs-hit-just-right-for-maximum-damage/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Tsunamis, wildfires followed dinosaur-killing impact

Killing Field From the Day the Dinosaurs Died Found in North Dakota
Some discoveries change everything. Most just explain a lot. A few explain a LOT. The latter is the case of a new discovery in North Dakota – a killing field formed perhaps no more than hours after the event that caused the mass extinction of dinosaurs 66 million years ago … the asteroid or comet… Continue reading Killing Field From the Day the Dinosaurs Died Found in North Dakota
