The United States found the largest dinosaur footprint

"USA Today" news that a research report published by academic journal Peerj on the same day pointed out that through the measurement and comparison of 3D scanning technology, American paleontologists believe that a footprint of about 1 meter was discovered in Wyoming 20 years ago. It belongs to the largest terrestrial animal on earth - the sauropod dinosaur. Scientists are temporarily unable to judge the exact type, but they analyze that this "bigfoot" is a close relative of the herbivorous dinosaur of the movie "Jurassic Park" - Brachiosaurus. According to the research report, this is the largest dinosaur footprint ever discovered.Emanuel Tschopp, a researcher at the American Museum of Natural History, said that this footprint must belong to the largest terrestrial animal of all time - the sauropod dinosaur.

According to the study, this giant footprint fossil was discovered by the University of Kansas expedition in 1998 in the Morrison Formation in Wyoming. Buried under the tail of a long-necked dinosaur. Scientists believe that it is a left hind footprint. They estimated that the dinosaur's hips could be as much as 4 meters from the ground.

The report also pointed out that this sauropod dinosaur lived in the eastern part of Utah to the vast mainland of northwestern Wyoming 150 million years ago. In contrast, other sauropods in this period have a smaller life span, Tschopp said.

The sauropod dinosaur was once the largest animal on land, mainly living in the Jurassic and Cretaceous, and contains more than 100 species. Most of them are giant vegetarian dinosaurs that walk on all fours. The head is small, the neck is long, the tail is long, and the teeth are small spoons. The largest sauropod dinosaur ever discovered by humans is the Patagonitan, which is 37 meters long.

According to Science News, the research team will continue to work in the Black Mountain region of Wyoming, hoping to find more dinosaur fossils.
