A remarkable discovery at Dewars Farm Quarry in England has uncovered over 200 fossilized dinosaur footprints dating back 166 million years to the Middle Jurassic period. These tracks, belonging to some of the largest dinosaurs to have roamed the United Kingdom, provide valuable insights into their movements and interactions.
Discovery and Excavation
The footprints were first noticed in June 2024 by quarry worker Gary Johnson, who spotted unusual formations while clearing clay from the quarry floor. Intrigued by the strange bumps, he reached out to experts at Birmingham and Oxford University. In response, a team of 100 scientists conducted a week-long excavation, carefully unearthing the footprints. The site revealed five distinct trackways, with the longest stretching an impressive 492 feet (150 meters).
Identifying the Dinosaurs
Archaeologists determined that four of the trackways were made by Sauropods—massive, long-necked, plant-eating dinosaurs that could grow up to 60 feet (18 meters) tall and weigh over ten tons. The fifth trackway was attributed to the Megalosaurus, a large, three-toed carnivore measuring around 30 feet (9 meters) long. This particular species holds historical significance as the first dinosaur to be officially named and described by scientists in 1824.
Possible Interaction Between Species
One of the most intriguing findings at the site was the overlap of carnivore and herbivore tracks, raising questions about whether these two species interacted. Researchers estimated that both dinosaurs moved at a pace similar to a human’s walking speed—approximately 3 miles (4.8 km) per hour.
“These footprints provide an extraordinary glimpse into the lives of dinosaurs, showcasing their movements, interactions, and the tropical environment they once inhabited,” explained Professor Kirsty Edgar from the University of Birmingham.
Advancements in Preservation and Research
This is not the first time dinosaur tracks have been found at Dewars Farm Quarry. In 1997, researchers discovered 40 sets of footprints, some extending up to 590 feet (180 meters). However, that section of the quarry is no longer accessible, and documentation at the time was limited due to the absence of digital cameras and drones.
The latest discovery, made public on January 2, 2025, is being extensively documented with modern technology. Scientists have captured over 20,000 high-resolution images and developed detailed 3D models to enable further research.
“There is still much to learn from this site, which is an invaluable part of our national Earth heritage,” said Professor Richard Butler from the University of Birmingham. “With our 3D models, researchers will be able to study and preserve this significant piece of history for generations to come.”
