Oxfordshire: ‘dinosaur highway’ Jurassic Footprints Reveal a Glimpse into Prehistoric Life

In a remarkable discovery at Dewars Farm Quarry in Oxfordshire, England, scientists have unearthed nearly 200 dinosaur footprints dating back 166 million years to the Middle Jurassic Period. This extensive track site, nicknamed the "dinosaur highway," is the largest of its kind in the United Kingdom and provides a unique window into the lives of the prehistoric giants that roamed the area.  

 

 

The find was initially made in 2023 when quarry worker Gary Johnson noticed unusual bumps on the ground while extracting limestone. This led to a collaborative excavation effort involving around 100 volunteers from the University of Birmingham and the University of Oxford. The team spent a week in June meticulously uncovering and recording the tracks, which hold significant scientific value.  

 

 

The discovery coincides with the 200th anniversary of the Megalosaurus, the first dinosaur species ever described, which was also found in Oxfordshire in 1824. "There’s a really long legacy in this area of exciting dinosaur tracks and body fossils," said Kirsty Edgar, a professor of micropaleontology at the University of Birmingham.  

 

 

These newly uncovered tracks connect to a previously discovered path at the same quarry in 1997, now inaccessible. Advances in technology, however, will allow researchers to extract new insights from the current find. The tracks reveal details about the dinosaurs' movements, speeds, and social behavior. Most of the creatures, including larger theropods such as the Megalosaurus, appeared to be moving northeast at an average speed of 5 kilometers per hour, a pace comparable to human walking speed.  

 

Analysis of the footprints suggests that the Megalosaurus, a predator, intersected paths with sauropods, large herbivores, as they moved through the area. "This theropod seemed to be moving at a leisurely pace, as indicated by the footprints," explained researcher Tanner. The intersecting paths hint at predator-prey interactions and suggest these dinosaurs may have been navigating along the shoreline, possibly to find food or avoid obstacles.  

The site’s preservation was made possible by the unique environmental conditions of the Jurassic Period. Soft sediment, combined with just the right amount of water, created the perfect medium for capturing and conserving the footprints. Edgar likened the ancient environment to the Florida Keys, with its carbonate mud banks and proximity to water. A subsequent storm likely covered the tracks quickly, shielding them from erosion and preserving them for millions of years.  

 

Unlike fossilized bones, which can be transported from their original location, footprints remain where they were made, offering invaluable insights into the daily lives of dinosaurs. Tracks can reveal group dynamics, predator-prey interactions, and how these creatures adapted to environmental changes. "It’s like a snapshot into the day of the dinosaurs’ life, and what they were doing," Edgar said.  

 

This discovery not only sheds light on the behavior and ecology of Jurassic dinosaurs but also underscores the importance of preserving and studying such ancient sites. The "dinosaur highway" at Dewars Farm Quarry stands as a testament to the enduring fascination with these prehistoric giants and the stories their footprints continue to tell.
