Winners and Losers in the Real Life Game of Asteroids

It was 65.5 years ago when the dinosaurs lost to the asteroids in the game of life. The story goes that an asteroid that was 6 miles across impacted the earth and left a dark cloud of debris over the earth that cooled temperatures and caused the dinosaurs to become extinct. However scientists think that there may have been a different explanation as to why these dinosaurs died out. Scientists have found that the Hadrosauridae family of dinosaurs were already on their way to extinction before the large asteroid hit the earth. This includes the famous duck billed dinosaurs and the triceratops. So, unlike before, the asteroid impact may not have wiped out all of the dinosaurs equally, but some dinos may have been weakened already, while others may have lived longer after the impact.
