When & Where
In 1855, at the junction of both Missouri and Judith rivers in Montana, United States, a group of fossilized sets of teeth were discovered. It was then found by a paleontologist named Ferdinand V. Hayden. After locating these fossils, it was then delivered to Joseph Leidy of the Academy of Natural Sciences of Philadelphia who in 1856 described this dinosaur as the Troodon, which is Greek for “wounding teeth”. Other remains of the Troodon were found in Wyoming and Alaska, in the United States and also in Alberta, Canada.
Size & Weight
The Troodon can reach up to a height of a meter of 3 feet, a length of 3 meters, or 10 feet, and a weight of up to 50 kilograms, or 110 lbs. This dinosaur’s hollow bones were one of the reasons that they are light weights.
Mobility & Diet
Even if small, this dinosaur is a carnivore. Its hind legs and small structure have helped in feeding off other reptiles. This dinosaur was believed to have fed off snakes, lizards, as well as other dinosaurs’ hatchlings.
- Troodon is the Greek word for “Wounding Tooth”.
- Lived in colder climates.
- Was known before as Stenonychosaurus.
- Troodon had a bigger brain than most dinosaurs.
- Just like other dinosaurs of their time, they reproduced by laying eggs.
- Unlike other dinosaurs, the Troodon was discovered to have its eyes facing forward. Most dinosaurs have their eyes positioned toward their sides. The Troodon having its eyes facing forward helped them see clearly at night and based on studies, they possess binocular vision as well.
