Tyrannosaurus rex was the apex predator of its time, roaming the river valleys and floodplains of western North America near the end of the Cretaceous Period. Growing over 40 feet long with a massive skull and bone-crushing bite, T. rex preyed on large herbivores like Triceratops and Edmontosaurus. Its keen sense of smell, forward-facing eyes for depth perception, and powerful legs made it both an efficient hunter and scavenger. Fossil evidence suggests these giants lived in a warm, seasonal environment teeming with life—an ecosystem they ruled until the very end of the dinosaur era.
