The prehistoric world continues to reveal its mysteries, and a groundbreaking discovery in Oxfordshire, England, has captured the imagination of scientists and the public alike. Deep within Dewars Farm Quarry, a “dinosaur highway” of nearly 200 footprints dating back 166 million years has come to light. This extraordinary find offers unparalleled insights into the Middle Jurassic period, showcasing the movements, interactions, and environment of some of Earth’s most iconic creatures.
A Remarkable Discovery at Dewars Farm Quarry
The story began when a sharp-eyed worker noticed unusual clay formations while digging in a limestone quarry. This simple observation set the stage for a major excavation in June 2024, involving over 100 researchers from the universities of Oxford and Birmingham. The result was nothing short of astonishing—a series of well-preserved dinosaur tracks, dubbed a “dinosaur highway.”
The site, located in southern England, expands on earlier paleontological work in the region. It provides fresh perspectives on the Middle Jurassic era, a period known for its lush tropical environments and the dominance of dinosaurs. The tracks tell a story of life millions of years ago, offering a rare glimpse into how these ancient giants moved through their world.

Meet the Dinosaurs of the Jurassic Highway
The tracks at Dewars Farm Quarry belong to two key players in the Jurassic ecosystem: the massive herbivorous sauropods and the formidable carnivorous Megalosaurus.
Cetiosaurus: The Gentle Giant
Four sets of tracks have been attributed to Cetiosaurus, a long-necked, plant-eating dinosaur that grew up to 60 feet (18 meters) in length. The tracks reveal slow, deliberate movements as these gentle giants roamed in search of vegetation. The footprints are remarkable in their detail, showing how the mud deformed under the immense weight of these creatures.
Megalosaurus: The Fearsome Predator
The fifth set of tracks belonged to Megalosaurus, a fierce carnivore measuring about 30 feet (9 meters) long. This predator left distinctive triple-claw prints, marking it as a formidable hunter. Notably, the Megalosaurus holds a special place in paleontology—it was the first dinosaur to be scientifically named nearly two centuries ago.
An intriguing aspect of the discovery is the area where the tracks of the herbivores and the carnivore intersect. This overlap raises fascinating questions about the interactions between these species. Was this an encounter between predator and prey, or were they simply moving through the same environment at different times?
Technology Unlocks Jurassic Secrets
The preservation of the tracks is a testament to a rare combination of natural events. Scientists believe that after the dinosaurs walked through the mud, a storm likely deposited a layer of sediment that sealed the prints, protecting them for millions of years.
Modern technology has played a crucial role in documenting and analyzing the site. The excavation team captured more than 20,000 digital images and used drones to create detailed 3D models of the footprints. These tools allow researchers to study the tracks in unprecedented detail, from the size and shape of the prints to the deformation patterns in the mud.
“The preservation is so detailed that we can see how the mud was deformed as the dinosaur’s feet squelched in and out,” explained Duncan Murdock, an earth scientist at the Oxford University Museum of Natural History. This level of detail provides valuable information about the size, weight, and walking speed of the dinosaurs, as well as the environment they inhabited.
Reconstructing a Jurassic Ecosystem
The tracks are more than just footprints—they are a window into a long-lost world. Fossilized burrows, shells, and plant remains found at the site paint a picture of a tropical lagoon environment. This lush habitat would have been teeming with life, providing food and shelter for a variety of species.
The tracks also offer insights into dinosaur behavior. For example, the spacing and depth of the footprints can reveal how fast the dinosaurs were walking and whether they were traveling alone or in groups. This kind of information helps paleontologists understand the social dynamics of these ancient creatures.
Building on Past Discoveries
The Dewars Farm Quarry site builds on earlier discoveries in the region. Nearly 30 years ago, another limestone quarry in Oxfordshire revealed 40 sets of dinosaur tracks, which were considered one of the world’s most scientifically significant track sites. However, much of that area is now inaccessible, and photographic evidence is limited because the discovery predated the use of digital cameras and drones.
The new excavation not only expands on the earlier findings but also highlights how advancements in technology and methodology are transforming paleontology. With digital documentation and 3D modeling, scientists can preserve and share these discoveries like never before, ensuring they remain accessible for future generations.
The Broader Significance of the Discovery
The “dinosaur highway” at Dewars Farm Quarry is more than just a scientific marvel—it is a reminder of the interconnectedness of life and the passage of time. These tracks provide a rare snapshot of a moment in history, capturing the movements of creatures that lived millions of years ago.
Emma Nicholls, a vertebrate paleontologist at the Oxford University Museum of Natural History, emphasized the ongoing nature of discovery: “Scientists have known about and been studying Megalosaurus for longer than any other dinosaur on Earth, and yet these recent discoveries prove there is still new evidence of these animals out there, waiting to be found.”
The findings also underscore the importance of preserving paleontological sites. Each discovery adds to our understanding of the past and helps us piece together the story of life on Earth.
A Glimpse into the Future
The significance of the Dewars Farm Quarry site extends beyond the scientific community. The findings will be featured in a new exhibit at the Oxford University Museum of Natural History and on the BBC’s Digging for Britain program. These public engagements highlight the role of paleontology in inspiring curiosity and connecting people to the natural world.
Looking ahead, researchers hope to continue studying the site to uncover more details about the dinosaurs and their environment. The digital models and extensive documentation created during the excavation will be invaluable for future studies.
Conclusion
The discovery of the “dinosaur highway” at Dewars Farm Quarry is a landmark moment in paleontology. It provides a vivid glimpse into the lives of dinosaurs, revealing their movements, behaviors, and interactions within a tropical Jurassic environment. As technology continues to advance, sites like this remind us of the enduring mysteries of the prehistoric world and the importance of exploring and preserving our planet’s ancient history.
