Death Valley desert in California often witnesses large and heavy rocks known as ‘sailing stones’ that regularly navigate across the landscapes, leaving long tracks behind them. Researchers have now revealed that a sandstone slab containing dinosaur footsteps might also contain the mark of a sailing stone. The slab, which has been on display since 1896, contains the shape of the foot and even skin texture of a prosauropod that lived during the Early Jurassic period. Researchers have decided to continue their research to collect more evidence for their study.
