Struthiosaurus
Struthiosaurus was a small armoured dinosaur that lived on islands in Europe. It had bony plates on its back for protection and ate plants. Scientists think it was a dwarf ankylosaur because it was much smaller than its relatives.21

Fun facts
Struthiosaurus had very poor hearing and relied mostly on its armour for defence.1
It was one of the smallest armoured dinosaurs, only about 2 to 3 metres long.1
Struthiosaurus lived on islands in Europe during the Late Cretaceous, which may have made it a dwarf species.2
Its name means 'ostrich lizard' because the first skull piece found looked bird-like.1
Scientists think Struthiosaurus was a slow and solitary animal.1
Three valid species of Struthiosaurus are known: S. austriacus, S. transylvanicus, and S. languedocensis.1
Myth buster
Myth: Some people think Struthiosaurus was a giant dinosaur.
