趣味知識

Duriavenator was first thought to be a Megalosaurus, but scientists later gave it its own name in 2008.1

The only known fossils of Duriavenator are parts of its skull and jaws, found in a quarry in 1882.1

Duriavenator had a deep groove on its upper jaw bone with many air-filled holes, which is a unique feature.1

It had about 4 teeth in the front of its upper jaw, 14 to 16 in the back of the upper jaw, and 14 to 15 in the lower jaw.1

The front teeth of Duriavenator were longer and pointed forward, which may have helped it grab food.1

Duriavenator lived during the Middle Jurassic period, about 168 million years ago, making it one of the oldest known tetanuran theropods.1

發現: In 1882, Edward Cleminshaw found skull bones near Sherborne, England. The fossils were first called Megalosaurus, but in 2008 Roger Benson renamed them Duriavenator.1
仍有爭議: Scientists are not sure exactly how big Duriavenator was because only a few skull bones have been found. The size estimates are based on related dinosaurs.1
