Washington: A river flowing through a drought in Texas dried up Dinosaur Valley State ParkUnraveling the track of giant reptiles that lived about 113 million years ago, an official said on Tuesday.
Photos posted on Facebook show three footprints down a dry tree-lined river in the southern US state. A caption accompanying the images says, “This is one of the longest dinosaur trackways in the world.”
Stephanie Salinas Garcia of the Texas Department of Parks and Wildlife said dry weather made the tracks visible.
“Due to extreme drought conditions last summer, the river dried up completely in most places, allowing more tracks to be opened in the park,” she said.
“Under normal river conditions, these new tracks are underwater and are usually filled with sediment, leaving them buried and not visible,” García said.
Most of the recently revealed tracks were made by Acrocanthosaurus, which as an adult weighed about seven tons (6,350 kg) and was 15 feet (4.5 m) long.
Another dinosaur, Sauroposidon, also left tracks in the park. It was 60 feet long and weighed 44 tons in adulthood.
The state park—located in an inland area southwest of downtown Dallas—was once on the edge of an ancient ocean, and dinosaurs left footprints in the mud, its website says.
While the drought exposed the tracks, rain is in the forecast, meaning they will once again be covered.
“While they will soon be buried again by rain and river, Dinosaur Valley State Park will continue to protect these 113 million-year-old tracks not only for the present, but for generations to come,” Garcia said.
