There are dinosaur footprints in Texas that are more than 100 years old.
Multiple dinosaur tracks belonging to the Acrocanthosaurus dinosaur were discovered recently at Dinosaur Valley state park in north-west Texas, as a river running through central Texas has dried up due to a lack of rain
The prints from the Acrocanthosaurus dinosaur were found in a dried up river. In an email to NBC News, the state park confirmed that the 15ft, seven ton creature was once in the area.
There are about 60 prints from the Acrocanthosaurus with an estimated 140 tracks from the dinosaur.
The Acrocanthosaurus is the dinosaur that most tracks that have recently been uncovered and discovered at different parts of the river in the park are related to.
Dinosaur tracks from the Acrocanthosaurus have not been seen in over a decade, but visitors can sometimes see other tracks at the state park.
The Sauroposeidon, a 66ft creature that weighed 48 tons when fully grown, was also found. It is believed that the Acrocanth preyed on Sauroposeidon.
Several states in the US are dealing with extreme dry weather.
Arizona, Nevada and Mexico will be affected by the federal government's decision to cut water use due to the dip in water levels.
The Lone Star state of Texas is experiencing a severe shortage of water due to the lack of precipitation.
There are other discoveries besides dinosaur prints. Human remains and a ship dating back to the second world war were found in the lake as water levels fell due to the long dry spell.
