酷東西

趣味知識

Eousdryosaurus had a very small big toe, which is why its species name is nanohallucis, meaning 'tiny big toe'.1

Its foot had a special toe bone formula of 1 to 3-4 to 5-0, meaning it had no fifth toe at all.1

Scientists think Eousdryosaurus is one of the oldest known dryosaurids, a group of fast-running plant-eaters.1

Only one fossil of Eousdryosaurus has been found, a single skeleton from the Alcobaça Formation in Portugal.2

Eousdryosaurus lived about 152 to 145 million years ago, during the Kimmeridgian and Tithonian ages.6
