Datos curiosos

1

Stenonychosaurus had very long, slender legs, so it could run fast.1

2

It had a large, sickle-shaped claw on each second toe that it held off the ground when running.1

3

Its eyes faced forward, giving it good binocular vision, which helps with judging distance when hunting.1

4

The teeth of Stenonychosaurus had large serrations with pits at the intersections, and the points pointed toward the tip of the tooth.1

5

Some scientists think it might have eaten plants because its jaws met in a broad U-shape, similar to an iguana.1

6

It lived in a warm coastal floodplain with forests, alongside big predators like Daspletosaurus and Gorgosaurus.1

As preguntas máis frecuentes sobre Stenonychosaurus

?How big was Stenonychosaurus?

Stenonychosaurus was a small dinosaur, up to 2.5 metres long and 35 kilograms in body mass. The largest specimens were about the size of Deinonychus and Unenlagia.12

?What did Stenonychosaurus eat?

Scientists think it was probably an omnivore, eating both meat and plants. Its teeth had large serrations and its jaws met in a broad U-shape, similar to an iguana, which suggests it could bite through tough plant material.12

?Was Stenonychosaurus smart?

Yes, it had one of the largest brains of any dinosaur relative to its body size, comparable to modern birds. It was probably cleverer than most dinosaurs, but not as smart as a human or a crow.12

?Could Stenonychosaurus run fast?

Yes, it had very long, slender hind limbs, which suggests it could run quickly. It also held its sickle-shaped claws off the ground when running.12

?When did Stenonychosaurus live?

It lived during the Late Cretaceous period, about 77 to 74 million years ago, in what is now Canada.2

?Is Stenonychosaurus a dinosaur?

Yes, it is a small theropod dinosaur, specifically a troodontid. Troodontids are a group of bird-like dinosaurs, not birds themselves.12

?Did Stenonychosaurus have feathers?

The sources do not mention feathers on Stenonychosaurus. However, it is closely related to birds and other feathered dinosaurs, but we don't have direct evidence from the fossils described.1

?Why did Stenonychosaurus have big eyes?

Its eyes were very large and slightly forward facing, giving it good depth perception. This might have helped it hunt, and some scientists think it may have been partially nocturnal.1

Cazamitos

Mito: Stenonychosaurus was a fierce meat-eater like other raptors.

Verdade: Its teeth and jaws look more like those of plant-eaters, so scientists now think it may have eaten both meat and plants.12
