The findings, published Thursday in Scientific Reports, reveal one of the fastest known sets of fossilized dinosaur footprints. To calculate the running speed, scientists measured the length of the footprint and took into account the dinosaur's hip height and stride length — the distance between two consecutive footprints of the same foot.
