The six mile-wide asteroid which struck the Earth 66 million years ago and ended the 180 million year-long reign of the dinosaurs, was the cause of what is known as a Chicxulub events. It landed in what is now the Yucatan peninsula in Mexico and formed the Chicxulub crater.
How big was asteroid that killed dinosaurs?
The impact site, known as the Chicxulub crater, is centred on the Yucatán Peninsula in Mexico. The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter – the second-largest crater on the planet.
What came after dinosaurs?
The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.

What are the 7 features of an impact crater?
The features that best determine an impact origin for a crater are (1) a circular rim crest outline, (2) flanks that gently rise [76] above the surrounding terrain, (3) floors with elevations lower than those of the surrounding terrain, (4) an ejecta blanket surrounding the crater, and (S) an inner basin that may be …

With their penchant for hunting, habitat destruction and the release of invasive species, humans undid millions of years of evolution, and swiftly removed this bird from the face of the Earth. Since then, the dodo has nestled itself in our conscience as the first prominent example of human-driven extinction.

What happens to the crater after void out?
However, expect it to remain for at least a day or so after the incident occurs.
