Yorkshire‘s hidden fossil haven reveals an exotic past
A derelict mining tip in Doncaster has given up its 310-million-year-old secrets after a host of new fossils – including some fossilised plants and creatures that may even be new to science – were found. One of the most exciting finds was that of a fossilised shark egg case, hinting at Yorkshire’s more exotic history.
Also among the fossils were some horseshoe crabs and previously unrecorded seed pods, all of which were found in preserved rocks that formed within the coal and shale deposits in what is one of the few fossil locations of its kind left in the UK.
The tip, located in Edlington, southwest of Doncaster, has been identified as being the only tip in the borough where fossils could still potentially be collected. All others in the area have been landscaped, or turned into parks, leaving any fossils that may be lying beneath inaccessible.
Palaeontologist Dean Lomax, a visiting scientist at the University of Manchester’s School of Earth, Atmospheric and Environmental Sciences, described what the fossils indicate Yorkshire might have been like hundreds of millions of years ago: “The fossils unlock a window into a long distant past, buried deep beneath residents’ feet. They are proof that parts of Yorkshire were once a tropical water-logged forest, teeming with life that may have looked something similar to today’s Amazon delta, a mix of dense forest, lakes, swamps and lagoons.
“The shark egg case is particularly rare and significant, because it’s soft bodied and an unusual object to find fossilised. We hope that future organised collecting of the site may reveal further rare discoveries, such as dragonflies, beetles, spiders and further evidence of vertebrates. And who knows, maybe we will even find the actual shark.”
It is hoped that further fossil specimens unearthed at the site will continue to be found. Speaking from Doncaster Heritage Services, Peter Robinson said: “We hope this important discovery will encourage ex-miners from the borough to bring forward and donate fossil specimens from the now defunct collieries, which were collected whilst extracting coal from the pit face. We have heard many stories of some of the wonderful fossils that have been found.”
The fossils are being safely stored at Doncaster Museum and have been integrated into the museum’s fossil collection.
