The Last Days of the Dinosaurs: An Asteroid, Extinction, and the Beginning of Our World

This narrative nonfiction book recounts the day the dinosaurs went extinct and its aftermath. Picture yourself in the Cretaceous period, 66 million years ago, on a sunny afternoon in Hell Creek, Montana. A Triceratops ambles along the forest’s edge. In hours, everything will be destroyed. Lush plant life will be replaced by fire, and the Tyrannosaurus rex and every other non-avian dinosaur will be wiped out.

The cause was an asteroid seven miles across that slammed into the Earth, creating a geologic wound over 50 miles in diameter. The mass extinction that followed saw over half of known species vanish overnight. This day was crucial for both humans and dinosaurs, as it opened evolutionary opportunities that had been closed for 100 million years.
