Asteroid that wiped out the dinosaurs 'came from beyond Jupiter'
Briefly

"The fate of the dinosaurs and many other species was sealed by this projectile from the outer reaches of the solar system," said Professor Dr Carsten Münker.
"C-type asteroids represent leftover building blocks of the outer solar system gas and ice planets," Dr Fisher-Gödde explained, highlighting the origin of the asteroid.
"Owing to the dynamic evolution of the solar system, with Jupiter's early migration, the orbits of asteroids got disturbed and they were scattered towards the inner solar system."
Dr. Mario Fischer-Gödde noted that the killer rock was a huge carbonaceous chondrite (C-type) asteroid, a carbon-rich type that is common in the solar system.
