Grange Top quarry becomes site of major palaeontological find
Remains of the world’s first pterosaur from the Middle Jurassic period have been uncovered at our Grange Top quarry in Rutland, which is adjacent to our Ketton cement works.
A large, hollow bone from the pterosaur, which is about 170 million years old, was found within the layers of Lincolnshire limestone, shedding new light on the prehistoric life that once soared above the Rutland countryside.
The discovery highlights the important role quarrying plays in uncovering our palaeontological history.
Aurelien Colas, Quarry Manager at Grange Top quarry said: “It’s truly exciting to see how the quarry has allowed for further understanding of Rutland’s prehistoric past.
“Without quarrying, these fossils would likely never be found as they are buried so deep beneath layers of rocks.”
The full wingspan of the fossil is tentatively estimated at between 3.5 to 4m and has been identified as a pterosaur (flying reptilian dinosaur) due to the thin-walled nature of the bone, which is typical of flying vertebrates such as pterosaurs and birds.
As well as being unusually large, it is also the first pterosaur from the Bajocian age, a period of time in the Middle Jurassic, found in the world, and most likely the first pterosaur recorded from Rutland.
The fossil was discovered by the Peterborough Geological and Palaeontological Group (PGPG), who regularly visit the quarry on weekends to carry out fieldwork, accompanied by Quarry Operative David Whittington.
The Bajocian age fossil will be on display at Rutland County Museum in Oakham from the end of October 2024, reflecting our commitment to contributing to the local community’s palaeontological and geological heritage.
Penny Sharp, Director for Places at Rutland County Council, said: “It’s tremendous to have yet another major discovery, following hot on the heels of the Rutland Water Ichthyosaur and 4th century Roman mosaic that have already been unearthed in the County. We’re excited that Rutland County Museum will be home to the pterosaur find and are looking forward to it going on display.”
