Affected by high temperature and dry weather, a river in Dinosaur Valley State Park in Texas, USA, dried up, and a large number of dinosaur footprint fossils have been seen again, the oldest of which can be traced back to 113 million years ago.

A park spokesman said most of the footprint fossils belonged to an adult Acrocanthosaurus, which was about 15 feet (4.6 meters) tall and weighed nearly 7 tons.

A park spokesman also said that under normal weather conditions, these dinosaur footprint fossils are located underwater, covered in sediment, and difficult to find. However, the footprints are expected to be buried again after rain, which also helps protect them from natural weathering and erosion.
