In a remarkable paleontological breakthrough, scientists have discovered the largest dinosaur trackway ever found in the UK, dating back 166 million years. Nestled in a quarry, this ancient site holds nearly 200 fossilized footprints, providing valuable insights into the daily lives and movements of dinosaurs during the Middle Jurassic period.

The tracks were uncovered during an excavation led by the Universities of Oxford and Birmingham, with a team of over 100 researchers, students, and volunteers working tirelessly. The footprints are so well-preserved that scientists can discern how the mud deformed under the dinosaurs’ weight, bringing a vivid clarity to these prehistoric imprints.

Dr. Duncan Murdock, an earth scientist at the Oxford University Museum of Natural History, marveled at the find, stating, “The preservation is so detailed that we can see how the mud was deformed as the dinosaurs’ feet squelched in and out.”

Insights From the Tracks

The trackway includes footprints from two primary dinosaur species:

• Cetiosaurus: A long-necked herbivorous sauropod measuring up to 18 meters. This plant-eating giant roamed on four legs, leaving deep, rounded impressions in the soft mud.
• Megalosaurus: A nine-meter-long carnivore with three-toed feet. Its sharp claws and agile movement are evidenced in the elongated, pointed footprints.

The trackways not only reveal the movements of these species but also hint at possible interactions. In some areas, the footprints of the sauropod and the predator overlap, raising intriguing questions about whether these interactions were coincidental or predatory.

“This is one of the most impressive track sites I’ve ever seen,” said Prof. Kirsty Edgar, a micropaleontologist from the University of Birmingham. “It’s a snapshot in time—a glimpse into the lives of creatures from millions of years ago.”

Technology Enhances the Study

Modern technology played a crucial role in documenting the site. Using drones, the researchers captured over 20,000 high-resolution images, which were used to create intricate 3D models of the trackways. These tools allow scientists to study the footprints in greater detail without disturbing the site.

Key technological contributions include:

• 3D Modeling: Precise reconstructions of footprints enable detailed analysis of dinosaur gaits and speeds.
• Aerial Imaging: High-resolution drone photography provided a comprehensive view of the trackways.
• Preservation Planning: Digital documentation aids in preserving the site for future generations.

Prof. Richard Butler of the University of Birmingham emphasized the importance of these innovations: “The really lovely thing about a dinosaur footprint, particularly if you have a trackway, is that it is a snapshot in the life of the animal.”

A Dynamic Ancient Environment

The footprints were preserved in what was once a shallow lagoon environment. Scientists theorize that a storm or similar event deposited sediment over the prints, protecting them from erosion and preserving them for millions of years. Along with other fossils like plant remains and burrows, the site paints a vivid picture of a thriving Jurassic ecosystem.

“It’s incredible to think that these tracks were made by dinosaurs just going about their daily lives,” said Prof. Butler. “The site provides a unique glimpse into the ecosystems of the Middle Jurassic period.”

Key Facts About the Discovery

Here are some highlights from the excavation:

• Age: Approximately 166 million years old.
• Species: Cetiosaurus and Megalosaurus.
• Track Lengths: The longest stretches over 150 meters.
• Team Involvement: Over 100 scientists, students, and volunteers contributed to the project.
• Technology Used: Drones, 3D modeling, and high-resolution imaging.

Connecting Past and Future

The discovery builds upon earlier finds in the region. In the 1990s, similar trackways were uncovered nearby, but the current excavation surpasses previous efforts in scale and technological precision. Plans are underway to preserve the site, with collaboration between researchers, quarry operators, and conservation organizations.

The significance of this discovery extends beyond the scientific community. The findings will be featured in a new series of BBC’s Digging for Britain and showcased in an exhibition titled Breaking Ground at the Oxford University Museum of Natural History.
