Fossilised remains of what scientists believe was the largest land dinosaur ever to have roamed Europe have been found in Portugal.
The dinosaur, a new species named Torvosaurus gurneyi, was up to 10m (33ft) long and weighed between four and five tonnes. Its head measured 1.15m from front to back and was filled with blade-shaped teeth up to 10cm (4in) long, suggesting it may have been near the top of the food chain and eaten other large dinosaurs.
Scientists found the bones north of Portugal's capital, Lisbon, and originally thought they belonged to a species from North America, Torvosaurus tanneri.
Its genus name, Torvosaurus, means "savage lizard." Its species name, gurneyi, honors James Gurney, the author and illustrator of the popular "Dinotopia" book series.
Torvosaurus gurneyi was not the only meat-eating dinosaur in its neighborhood.
For example, there was a European species of the well-known North American Jurassic predator Allosaurus, but the Torvosaurus found in Portugal was larger. Torvosaurus gurneyi not only is the largest known meat-eating dinosaur from Europe, but is the biggest land predator of any kind ever found on the continent, they added.
