“Dinosaur Highway”: Hundreds of Giant Footprints in UK Quarry Shock the World

In a discovery that has electrified paleontology, scientists have unveiled Britain’s largest-ever dinosaur track site at Dewars Farm Quarry in Oxfordshire — a sprawling “dinosaur highway” of more than 200 mᴀssive footprints criss-crossing a 166-million-year-old limestone surface.

Led by researchers from the Universities of Oxford and Birmingham, the team exposed five extensive trackways during 2024–2025 excavations, with the longest sauropod trail stretching over 150–220 metres — one of Europe’s longest continuous dinosaur trackways.

Four trackways belong to gigantic long-necked herbivores, most likely Cetiosaurus, reaching up to 18 metres in length. A fifth was left by the fearsome theropod Megalosaurus, Britain’s first named dinosaur, roughly nine metres long. The prints reveal herds of sauropods moving together while the predator stalked the same ancient floodplain.

This Middle Jurᴀssic scene once lay in a lush, tropical environment of rivers and lagoons — far from today’s temperate Britain. The sheer density of tracks suggests regular migration routes or watering-hole gatherings, offering rare behavioral insights impossible from bones alone.

Originally hinted at by 1990s finds at nearby Ardley Quarry, the new exposure makes Dewars Farm the UK’s biggest dinosaur footprint site and arguably one of the largest mapped trackways worldwide.

Experts call it a “superhighway” that rewrites our picture of Jurᴀssic Britain: these giants weren’t solitary wanderers but part of thriving, interconnected ecosystems. With further quarrying expected to reveal even more tracks, the Oxfordshire “dinosaur highway” proves the UK still guards prehistoric wonders that continue to astonish the world.
