A British paleontologist has discovered not one, but two new species of dinosaur while studying fossils in a Canadian museum. Dr Nick Longrich was examining fossilised bones from two horned dinosaurs, which had been kept in the Canadian Museum of Nature for 75 years. And he found that, while they had previously been classified as a species from Canada, they more closely resembled dinosaurs from the American south west - suggesting they are a new species. This illustration shows Pentaceratops aquilonius, a new species of dinosaur discovered by a British paleontologist in a Canadian museum.

He made the finding while working at the Canadian Museum of Nature
@highlight
The fossilised bones from two dinosaurs had been stored for 75 years
@highlight
Previously they were thought to be species from Canada called Anchiceratops and Chasmosaurus
@highlight
But Dr Longrich said they are new species from western North America
@highlight
One is a species of Pentaceratops, and the other is Kosmoceratops
@highlight
Both lived in the Cretaceous Period about 75 million years ago
With @placeholder dinosaurs, we see a lot of large species in a single habitat.
