Dinosaur tracks from 113 million years ago have been revealed in Texas after a severe drought dried up a river.
The footprints – left by a single acrocanthosaurus – had not been seen for more than 20 years.
Footage of the find at the Dinosaur Valley State Park in Glen Rose was filmed by Paul Baker.
He said: “Sweep a little bit of the dust and dirt away, this is what you’ll find: dinosaur tracks.”
The tracks are usually under water, but a recent drought saw the level of the Paluxy River drop significantly.
Experts have taken the opportunity to map and monitor the dinosaur trackway before the river fills up again.
Texas Parks and Wildlife told reporters that while the tracks will be buried again by the rain and the river, the park “will continue to protect these 113-million-year-old tracks not only for present, but future generations”.
The acrocanthosaurus – which stood at around 15ft tall and weighed approximately seven tons – was an early cousin of the Tyrannosaurus rex.
