Albertonykus was a tiny dinosaur that used its strong, short arms to dig into insect nests for food. It was one of the smallest meat-eating dinosaurs ever found in North America, about as long as a big cat.2 3

酷東西

趣味知識

Albertonykus is the smallest alvarezsaur ever found in North America, measuring only 1.1 metres (3.6 feet) long.2

Its arms were very short but extremely strong, with a huge claw on the thumb for digging.3

Scientists think Albertonykus ate wood-nesting termites because fossil wood from its time contains termite-like tunnels.3

It lived about 72 to 66 million years ago, during the Late Cretaceous period.1

Albertonykus had long, slender legs and could probably run fast to escape predators.3

Its fossils were found in the same bonebed as the giant predator Albertosaurus.3
