Dinosaur tracks from 113 million years ago uncovered due to severe drought
inosaur 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”.
The dinosaur walked that trail for about 100 feet. There are an estimated 140 tracks in total from this one dinosaur, with about 60 visible now.
Tourists can pay to look at dinosaur tracks, often found near the Paluxy River, near the state park.
The 1,587-acre Dinosaur Valley State Park opened in 1972.
Tracks from the park are on display at the American Museum of Natural History in New York.
About 27 per cent of Texas is under “exeptional drought”, and 62 percent is in “extreme drought”.
Droughts across America and Europe have led to a number of waterways shrinking to reveal historical wonders.
Spain’s Stonehenge has been exposed in the corner of a reservoir where authorities say water levels have dropped to 28 per cent capacity.
The stones are believed to date back to 5000 BC.
In England, it was revealed in June that the remains of Europe’s largest ever land-based hunter were found on the Isle of Wight.
Several prehistoric bones belonging to the two-legged, crocodile-faced spinosaurid dinosaur were discovered and analysed by scientists from the University of Southampton.
The creature lived on the island 125 million years ago and would have fed on fish and a variety of other small to medium-sized animals, including dinosaurs.
PhD student Chris Barker said: “This was a huge animal, exceeding 10m (32.8ft) in length and probably several tonnes in weight. Judging from some of the dimensions, it appears to represent one of the largest predatory dinosaurs ever found in Europe — maybe even the biggest yet known.
