吃：植物有喙的草食恐龍白堊紀早期

Brighstoneus was a big, plant-eating dinosaur that lived on the Isle of Wight in England about 125 million years ago. It had a strange, bulbous nose that made it look different from its relatives. Scientists think it used its big nose to show off to other dinosaurs or to scare away rivals.1 2

酷東西

趣味知識

Brighstoneus had a bulbous bump on its nose, called a nasal bulla, which made its snout look S-shaped from the side.1

Its fossils were found mixed up with the bones of a meat-eating dinosaur called Neovenator after a storm in 1978.1

The dinosaur was named by a retired doctor, Jeremy Lockwood, who spent years studying old bones in museum collections.2

Brighstoneus lived in a floodplain environment that had rivers, lakes, and frequent wildfires.1

Its teeth were different from other similar dinosaurs because they had ridges on both sides.2

The name Brighstoneus honors the village of Brighstone, where a famous Victorian fossil collector named Reverend William Fox once lived.1
