One Cosmic Rock: The Story of the Asteroid that Changed Our World

A poetic look at a defining event in Earth’s history. Sixty-six million years ago, an asteroid hurtled through space toward an ancient Earth that looked very different from the one we know today. Back then, enormous creatures towered over marshes, soared above forests, and ruled the seas, while smaller life-forms scurried and snarled, swam and bloomed. Then-SMASH!-an icy cosmic rock crashed into the planet, and life on Earth was completely changed. Though many species were made extinct because of this one cosmic rock, some life found a way to continue and develop over millions of years, eventually evolving into the diverse life-forms-including humans!-that thrive on our planet today. With poetic text, stunning illustrations, and a child-centered conclusion, this accessible narrative nonfiction is perfect for STEM collections and sparking thought-provoking conversations about Earth’s history, the extinction of the dinosaurs, and evolution.
