2009 $4 .9999 Silver Coin: Dinosaur Fossils - Tyrannosaurus Rex Coin
It is a discovery that sends hearts pounding—and opens a
window to the mystifying world of dinosaurs. Their fossilized
bones testify to the massive beasts that once ruled the earth but
disappeared suddenly 65 million years ago.
During the time of these great beasts, a great inland sea covered
much of western Canada and the area now known as Alberta and
Saskatchewan was a lush subtropical shore—and home to over 35
dinosaur species. As these animals died, the evolving landscape
covered their bones with centuries of mud and sand—only to be
revealed when the glaciers from the last Ice Age scraped away the
top layers of rock and exposed bits of fossilized bone. Discovered
by paleontologists in the late 1800's, they inspired generations of
dinosaur hunters and established Canada as one of the richest
sources of Late Cretaceous fossils on earth.
Tyrannosaurus rex was one of several large carnivore (tyrannosaur)
species that lived in Alberta, appearing shortly before the
mysterious mass extinction. Its name means "tyrant lizard" and
there is no doubt it still rules today as the most popularized image
of these prehistoric animals.
The mighty Tyrannosaurus rex measured up to 12 m (39 ft) from
head to tail. It had a gaping one-metre (3 ft) bite with 10 to 15
cm (4 to 6 in) long teeth that could rip out hundreds of pounds of
flesh at a time.
