Diracodon

It was an herbivore, meaning it ate plants like low-lying bushes and shrubs.32

Scientists estimate it was about 9 metres (30 feet) long and weighed over 6.9 metric tons (7.6 short tons).2

Yes, like other stegosaurs, it probably had kite-shaped upright plates along its back and spikes on its tail, though direct evidence from its fossils is missing.2

It lived during the Late Jurassic, about 155 to 145 million years ago.2

Its fossils have been found in North America, especially in Wyoming and Colorado.32

Yes, it is a plated dinosaur (a stegosaur) that walked on four legs and ate plants.2

Many scientists think Diracodon might be the same animal as Stegosaurus, because their fossils are very similar.3

Probably only about 13 km/h (8 mph) at its fastest, about as fast as a kid running fast. This is an estimate. As a large, heavy stegosaur it moved slowly on four legs.2

The name Diracodon means 'two-point tooth' or 'two-ray tooth', though scientists are not sure exactly what it refers to.2

There is no direct evidence, but as a land-dwelling dinosaur it likely could not swim well.3
