One of the largest turtles ever to have existed, Archelon measures almost 5m in length and weighs as much as three tonnes. Dating back to the late Cretaceous period, this carnivorous reptile has a sharp beak and powerful flippers, making it an expert hunter. Unlike most modern-day turtles, its shell is soft – although it is tough enough to withstand attacks from predators. The name Archelon translates from ancient Greek as ‘first turtle’.
