16,000 Dinosaur Footprints Found in Bolivia
Scientists found 16,600 dinosaur footprints in Bolivia.
These footprints are from a type of dinosaur called theropods, which includes the T. rex.
The footprints are about 60 million years old and show how these dinosaurs moved and behaved.
Some footprints even show dinosaurs trying to swim.
The scientists think the dinosaurs might have been visiting a large, ancient lake.
The footprints are very well preserved, but human activities like farming and quarrying have threatened them.
The scientists will keep studying the site to find more footprints and learn more about these dinosaurs.
16,600 dinosaur footprints from theropods, including T. rex, found in Toro Toro, Bolivia.
Footprints are 60 million years old and show dinosaur behavior, including swimming attempts.
Preservation of footprints is excellent, with some tracks sealed by rising water levels.
Human activities like farming and quarrying have threatened the footprints' preservation.
The reason for the high concentration of footprints remains a mystery, with theories including a visit to an ancient lake or fleeing from something.
