Facts About TYRANNOSAURUS REX

Tyrannosaurus rex was one of the largest carnivorous dinosaurs ever to walk the Earth, measuring up to 40 feet long and weighing around 9 tons. This apex predator roamed North America during the Late Cretaceous period, approximately 68 to 66 million years ago.

T. rex had a bite force estimated at 12,800 pounds, making it one of the most powerful biters in the animal kingdom. Its massive jaws were lined with sharp, serrated teeth designed to tear through flesh and bone. Despite its size, T. rex was surprisingly agile, with powerful hind legs that allowed it to run at speeds up to 25 miles per hour.

Recent fossil evidence suggests that T. rex had feathers or feather-like structures covering parts of its body, challenging the scaly reptile image popularized in earlier depictions. Scientists believe these feathers may have been used for insulation, display, or brooding eggs rather than flight.

The name Tyrannosaurus rex means "tyrant lizard king," derived from Greek and Latin. Fossils of this iconic dinosaur have been discovered primarily in the western United States, with the most famous specimen being "Sue," housed at the Field Museum in Chicago.
