An employee excavating clay in a limestone quarry located in southern England observed peculiar elevations that led to the uncovering of a “dinosaur highway” and nearly 200 footprints estimated to be 166 million years old, researchers reported on Thursday.
This remarkable discovery, made after a team exceeding 100 individuals conducted excavation at the Dewars Farm Quarry, in Oxfordshire, during June, builds on prior paleontological research in the region and provides enhanced understanding of the Middle Jurassic epoch, state scientists from the universities of Oxford and Birmingham.
“The footprints present an incredible glimpse into the lives of dinosaurs, disclosing particulars about their motions, social behaviors, and the warm climate they thrived in,” stated Kirsty Edgar, a micropaleontology professor at the University of Birmingham.
Four of the track sets comprising the so-called highway illustrate routes taken by gigantic, long-necked herbivores known as sauropods, believed to be Cetiosaurus, a dinosaur reaching nearly 60 feet (18 meters) in length. A fifth set was attributed to the Megalosaurus, a menacing 9-meter predator known for its distinctive triple-claw imprint, being the first dinosaur scientifically designated two centuries ago.
A region where the footprints intersect prompts inquiries regarding potential interactions between the carnivorous and herbivorous species.
“Scientists have been aware of and examining Megalosaurus longer than any other dinosaur on the planet, and yet these recent findings confirm that novel evidence of these creatures still exists, awaiting discovery,” remarked Emma Nicholls, a vertebrate paleontologist at the Oxford University Museum of Natural History.
Almost 30 years ago, 40 sets of footprints uncovered in a limestone quarry in the vicinity were deemed one of the most scientifically valuable dinosaur track sites worldwide. However, that location is largely inaccessible now, and photographic documentation is limited as it occurred before the advent of digital cameras and drones to capture the evidence.
The team that operated at the site this summer gathered over 20,000 digital images and employed drones to create 3-D representations of the prints. This extensive documentation will support future research and could illuminate details about the dimensions of the dinosaurs, their locomotion, and their speed.
“The preservation is so intricate that we can observe how the mud was distorted as the dinosaurs’ feet sunk in and out,” explained Duncan Murdock, an earth scientist at the Oxford museum. “Alongside other fossils such as burrows, shells, and vegetation, we can reconstruct the muddy lagoon habitat the dinosaurs traversed.”
The discoveries will be displayed at a new exhibition at the museum and will also be featured on the BBC’s “Digging for Britain” program in the coming week.
