Adult T. Rex Footprint Sequence Discovered in North Dakota

Scientists have discovered the first known sequence of footprints left by an adult Tyrannosaurus rex in North Dakota, according to The Guardian and Good News Network.

The Guardian reported that the trackway stretches 23 feet and contains four three-toed footprints: two left and two right. It dated the tracks to 66.5 million years ago, while Good News Network’s headline described them more broadly as 66 million years old.

Good News Network reported that isolated adult T. rex footprints had previously been found, distinguishing this discovery from those individual impressions. The newly identified tracks form a sequence rather than a single footprint.

According to Good News Network, the trackway provides new insights into how the predator moved. The supplied Guardian excerpt gives the trackway’s dimensions and footprint arrangement, but neither excerpt describes specific findings about the animal’s movement.
