ALLOSAURUS “Other lizard” Late Jurassic, 155-150 million years ago
Allosaurus was probably the most common – and successful – carnosaur of the late Jurassic. It was a large but speedy predator, running up to 20 mph. It had sharp, powerful teeth and two ornate ridges along its skull, one above each eye. It was first discovered in the late 19th century, and enjoyed several decades of well-deserved fame before the garish Tyrannosaurus Rex eclipsed it in popularity. Experts agree that this elegant hunter was too noble to hold a grudge, and doesn’t need your pity.
