Dinosaurs were reptiles that evolved an upright gait (above left) similar
to that of mammals, ie their legs were straight, perpendicular
to the ground and supported the weight of the body so that
they could walk or run more easily. Other reptiles and modern
lizards have a sprawling gait (above right). Dinosaurs ruled
the Earth for 160 million years.
