Ancient tracks discovered at the bottom of what was once a huge lake suggest that dinosaurs could swim.
The footprints are around 125 million years old and were likely caused by a large meat-eating dino clawing at the sediment on the lake floor as it swam in around 10 feet of water. They are very different from the tracks left on land, as you cannot see the shape of the foot. The ripple marks surrounding the scratches make scientists think that the animal was swimming against the current.
According to one scientist involved in the discovery:
“The dinosaur swam with alternating movements of the two hind limbs: a pelvic paddle swimming motion,”
“It is a swimming style of amplified walking with movements similar to those used by modern bipeds, including aquatic birds.”
