Dinosaur tracks dating back 113 million years have been exposed after a river dried up in a drought-stricken US state park.
The Acrocanthosaurus tracks were discovered in Dinosaur Valley State Park in Texas on Monday.
The park said most tracks that have recently been discovered at different parts of the river belong to Acrocanthosaurus, which was an early cousin of the Tyrannosaurus rex.
The dinosaur species would stand about 15 feet tall (4.5 metres) as an adult and weigh close to seven tons. The other species that left tracks behind at the park was the enormous Sauroposeidon, which would be about 60 feet tall and weigh about 44 tons as an adult.
Park superintendent Jeff Davis told the BBC that the recently exposed tracks are called the “Lone ranger trackway”.
