Scientists say the footprints belong to at least six different dinosaur types
Scientists in China say they have discovered more than 3,000 dinosaur footprints, all facing the same way.
The footprints – thought to belong to at least six dinosaur types – were found in eastern Shandong province, state news agency Xinhua reports.
Experts believe the prints are more than 100 million years old and say they could represent a migration or a panicked attempt to escape predators.
Dinosaur fossils have been found at about 30 sites in the Zhucheng area.
As a result, Zhucheng City has become known locally as “dinosaur city”.
The footprints were uncovered on a 2,600 sq m (0.64 acre) rock slope in a gully following three months of excavation work, Xinhua reported.
The find is unusual because of the quantity and size of footprints uncovered, scientists said.
