Troodon was a carnivore (meat-eater) that lived in North America
during the late Cretaceous period,
about 74 to 65 million years ago.
It was one of the
dinosaurs that died out in the Cretaceous-Tertiary
extinction
65 million years ago.
Troodon was about 6 feet (1.8 meters) long, 3 feet (0.9 meters) tall, and probably weighed about
130 pounds (60 kilograms).
Troodon was one of the cleverest dinosaurs, having a large brain
in proportion to its body weight. It was probably about as smart as a modern bird.
Some scientists have even suggested
that were it not for the Cretaceous-Tertiary extinction,
Troodon, or one
of its relatives, may eventually have evolved human-level intelligence!
In
1982,
paleontologist Dale Russell and taxidermist/artist Ron Sequin created
a model of a "Dinosauroid" based on their speculation of
what an intelligent evolved descendant of Troodon might have looked like.
The name Troodon means "wounding tooth" and refers to the animal's
sharp teeth with serated edges.
Troodon was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Troodon was not closely related to lizards, it did have similarly shaped pelvic bones.
Troodon was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Troodon was not itself an ancestor of birds).
Troodon lived between about 74 million years ago and 65 million years ago, during the late Cretaceous period.
Troodon was about 6 feet (1.8 meters) long, and about 3 feet (0.9 meters) tall.
Troodon weighed about 130 pounds (60 kilograms).
