Megalosaurus Footprints being Prepared for Display
Fossilised tracks made by a fierce Jurassic carnivore when Oxfordshire was part of a sub-tropical paradise have made a perilous journey to their new home, where they will go in display in the Autumn.
The fossil footprints, measuring 50 cm across have been transported from the temporary storage site to the Oxfordshire Museum, where they will feature in a permanent exhibit dedicated to the dinosaur that is believed to have made these prints – a Megalosaurus.
The short trip to the museum marks the end of 10 years of excavation and planning after the trackway was first uncovered at a landfill site in Ardley, close to Bicester. The twenty-five mile trip from the storage site, where the fragile prints were prepared for their perilous journey, to the museum took five hours. Project Manager, Tom Freshwater, who works at the Oxfordshire Museum, commented:
“The prints weigh three tons each so the main challenge has been getting them into the garden, where they will be displayed. They had to be lifted very gently and smoothly because the rock is quite fragile and there are already cracks within the stone so we had to make sure that did not get worse.”
The fossil dinosaur footprints had been excavated in sections, of approximately 1 cubed metre, they were encased in plastic sheeting to protect them and set on steel plates to support the weight of the stone as the rocks made their journey. Having arrived safely at the Museum, each block was carefully winched over the Museum boundary fence into a specially prepared garden area. A great deal of care had to be taken as each block was lifted off the lorry, swung over the fence and placed in position. Despite their weight, the blocks are delicate and every precaution was taken to prevent any damage to the fossils.
The Museum plans to create a replica of the Jurassic environment and display the prints alongside a life-size model of a Megalosaurus. About 30 to 40 prints were originally discovered at Ardley Landfill and Recycling Centre, run by Viridor Waste Management, and those not been transferred have been preserved in situ. The prints are very important as meat-eating dinosaur tracks are exceptionally rare and these particular prints, believed to have been made by a Megalosaur provide evidence of a change of speed of the animal. The spacing between the prints gets longer, indicating a bigger stride length and an increase in speed of the animal.
The exhibit is likely to be opened in October.
