Alaskan Troodon was first seen when one was drinking water by a herd of Edmontosaurus. At nightfall, a gang of three Troodon attacked the hadrosaurids, a young Edmontosaurus was separated from the herd. The Troodon caught it, and almost killed it before the parent arrived, killing one Troodon by crashing into it and knocking it away. The rest of the Troodon fled. The next morning, the young Edmontosaurus was seen lying dead on the ground.
Troodon is said to be a carnivore is the show. However, it was a omnivore, yet recent studies found it had no wear marks on its teeth suggest it ate soft foods like meat rather than insects and plants.
Troodon was actually covered fully in feathers, with wing feathers covering its arms, unlike how it was depicted in the program.
Troodon and it’s relatives in general had small ”sickle claws” on their feet and likely fed on small animal.
