It is 166 million years old.. The discovery of the largest dinosaur traces site in Britain

Nearly 200 dinosaur footprints were discovered this summer in a quarry in the city of Oxfordshire in southeastern England, the largest such site ever in the United Kingdom, the Universities of Oxford and Birmingham announced Thursday.
The remarkable footprints left by five dinosaurs 166 million years ago will be revealed as part of the archeology program (“Digging for Britain”) on January 8.

Old track

The longest tracks followed by one of these extinct animals extends 150 meters in length at the Dewars Farm quarry, in what constitutes a “dinosaur highway” in which the paths of herbivores and carnivores intersected during the Middle Jurassic period.
“It is very rare to find such large numbers in the same place, and to discover such extensive paths,” said Emma Nicholls, a paleontologist specializing in vertebrates at the Natural History Museum at the University of London.
According to Nichols, this discovery may belong to one of the largest fingerprint sites in the world.

Different types

Scientists do not know exactly what factors contributed to the preservation of these footprints in the mud, “but it is possible that a storm left sediment on the footprints, which helped freeze them,” said paleontologist Richard Butler from the University of Birmingham.
Among these traces, four were left by sauropods, long-necked herbivorous dinosaurs, most likely from the Cetosaur family. These animals reached a length of 18 meters, and their footprints resemble those of an elephant, but are much larger.
The fifth trace was likely left by Megalosaurus, the largest predator in the Jurassic period in England. It walked on two legs and its three claws could be clearly seen in the ground.
