About 66 million years ago an asteroid the size of Mount Everest traveling at 45,000 miles per hour hit what is now the Yucatan Peninsula in Mexico. We can’t change the past, but still: what if that asteroid had missed? What would the Earth look like today if dinosaurs were still alive?
Some scientists say that the dinosaurs’ numbers had already been steadily declining for thousands of years before the asteroid hit, so they may have died out on their own without a mass extinction event. Still, the environment might not have suited early mammal populations, and they might not have been able to adapt quickly enough.

-Dinosaurs existed in the late Triassic, Jurassic, and Cretaceous periods during the Mesozoic era, which encompassed 180 million years. Earth at that time had a very warm climate with mild seasonal changes and no polar ice. The supercontinent Pangea had only just started to break down into smaller land masses that would millions of years later become the seven continents we know today.
-This infamous asteroid, basically an enormous space rock, became a fireball when confronted with friction and gravity in the Earth’s atmosphere, and it collided with a force of 100 million megatons. Smaller species living in the western hemisphere were able to survive the heat it all caused underground. But the big guys, like the triceratops and t-rex, were baked alive.
-The asteroid could’ve continued on its path without getting sucked in by the Earth’s gravitational pull, missing the planet completely, and letting the dinosaurs live out the rest of their natural lives in peace.
-In the purely hypothetical situation where dinosaurs never went extinct, their brains would’ve continued to adapt and evolve along with their bodies. Some scientists say that the dinosaurs’ numbers had already been steadily declining for thousands of years before the asteroid hit, so they may have died out on their own without a mass extinction event.
