When it lived: it lived 67-65 million years ago in the Late Cretaceous.

What it ate: T.rex ate meat. Palaeontologists have debated whether it was a scavenger or if it hunted its own food. Teeth marks are found in other dinosaurs which match a T.rex tooth. T.rex likely did both like many animals do today.

Weapon of choice: a massive head with rows of teeth up to 20cm long. Despite its reputation from Jurassic Park, T.rex had excellent vision. Standing still wouldn’t save you if it had you in its sights.
