Dinosaurs appear to have beaten humans to the moon by a few million years – and their remains could even be on Mars, experts have said.
The animals which inhabited our planet are likely to have travelled to outer space on the debris caused by the asteroid that wiped them out – so they won't have been alive when they made it to Earth's orbit.
The incredible claim was made in Peter Brannen's The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth's Past Mass Extinctions.
The extract from the book, which reports how scientists are uncovering clues about what caused five catastrophes which dragged life on Earth to the very edge of extinction, has recently gone viral racking up thousands of retweets on Twitter.
Over 66 million years ago, an asteroid later called Chicxulub, collided with planet Earth and triggered earthquakes, volcanic eruptions and tsunamis.
And in his book Brannen tells the story of the asteroid which hit the Yucatán Peninsula in Mexico, all but wiping out all dinosaur life on Earth.
In the book, writer Peter Brannen wrote: "A rock larger than Mount Everest hit planet Earth travelling twenty times faster than a bullet.
"This is so fast that it would have traversed the distance from the cruising altitude of a 747 to the ground in 0.3 seconds.
"The asteroid itself was so so large that, even at the moment of impact, the top of it might have still towered more than a mile above the cruising altitude of a 747.
"In its nearly instantaneous descent, it compressed the air below it so violently that it briefly became hotter than the surface of the sun."
He also explains that the meteor that hit Earth was traveling at such tremendous speed that "as the asteroid collided with the earth, in the sky above it where there should have been air, the rock had punched a hole of outer space vacuum in the atmosphere."
He added: "As the heavens rushed in to close this hole, enormous volumes of earth were expelled into orbit and beyond — all within a second or two of impact."
A previous study has also said that the asteroid that wiped out the dinosaurs may have catapulted life to Mars and the moons of Jupiter.
"We find that rock capable of carrying life has likely transferred from both Earth and Mars to all of the terrestrial planets in the solar system and Jupiter," said lead author Rachel Worth, of Penn State University, after the study was published in 2013.
"Any missions to search for life on Titan or the moons of Jupiter will have to consider whether biological material is of independent origin, or another branch in Earth's family tree."
