In the Grand Canyon found traces of an unknown ancient reptile

Unknown reptile lived on Earth 310 million years ago.

The researchers note that the set of footprints stretches to the meter and unusual way – on the diagonal. The traces belong to the Carboniferous period when the Earth was inhabited by plants gymnosperms and the first reptiles. “The tracks look as if two lizards walked side by side. But lizards don’t walk side by side, it does not happen” – said Professor, University of Nevada Stephen Rowland.

Scientists have put forward a few options of moves that would leave such strange prints, if an unknown reptile that has knocked with purpose. It could be, for example, side wind: if he was strong enough, it could cause the animal to move diagonally. Another option – a strong inclination, which was then surface also smashable animal when walking. It’s still possible that traces are left in the competition with the enemy or some kind of ritual to attract a mate.
