In Texas, a river that has shrunk due to a severe summer drought has turned up dinosaur footprints that date back more than 113 million years.
The enormous prints in the muddy Paluxy Riverbed were shown in photographs and a video that were posted by Dinosaur Valley State Park in Fort Worth on Tuesday.
Acrocanthosaurus leaves most of the tracks that have lately been excavated and found in various locations across the park.
This dinosaur would have been close to seven tons in weight and roughly 15 feet tall as an adult
There have also been tracks from Sauroposeidon found in the park, which stood 60 feet tall and weighed 44 tons millions of years ago.
Although one dinosaur probably made the longest set of tracks discovered at the park, they are anticipated to disappear once the rains start up again.
Park manager Jeff Davis told ABC News that the river will deposit silt and sediment on top of the tracks. "That is what keeps them intact. They have survived for approximately 113 million years because of this."
Long-term droughts have exposed further submerged artifacts when water levels in lakes and rivers around the world decline.
A number of human remains have been found in Lake Mead as water levels in Arizona and Nevada reach historic highs, and a number of sunken WWII German ships have emerged along the Danube River as Europe suffers from its worst drought in 500 years.
