DID YOU KNOW?
Sixty-six million years ago, the world burned. An asteroid crashed to Earth with a force one million times larger than the largest atomic bomb, causing the extinction of the dinosaurs. But dinosaurs weren’t the only ones. In a new study, scientists learned the planet’s forests were decimated, leading to the extinction of tree-dwelling birds. The birds that did survive were ground-dwellers, whose fossilised remains show longer, sturdier legs like modern kiwis and emus. “The end-cretaceous event is the fifth mass extinction – we’re in the sixth,” paleontologist and co-author of the study in Current Biology Regan Dunn said. “It’s important for us to understand what happens when you destroy an ecosystem ... so we can know how our actions will affect what comes after us.”
