Sunday 16th July saw a UKAFH hunt to Salthill Quarry Local Nature Reserve, Clitheroe, Lancashire. Salthill is a former limestone quarry and is known not only for its important geological formations but also the rare wildlife that can be found here. It has been designated a Site of Special Scientific Interest (SSSI) and because of this no hammers were allowed on site, but fossils here could be found loose in the spoil, so all that was needed a was a keen eye!
The rocks at Salthill formed during the Carboniferous period in a shallow, warm tropical sea, like today’s Caribbean, and are packed with crinoid fossils. The site even includes a bench made with panels of carved crinoids.
The day started with a great animated talk from UKAFH leader, Andrew Eaves, on the types of fossils that could be found at the site, before everyone got stuck in and it was all eyes to the ground! It wasn’t difficult – crinoids were abundant and crunched underfoot in places. No members went home empty-handed! Many crinoid columnals were found, along with isolated ossicles and less-commonly, crinoid thecae. Andrew pointed out the rarer blastoids in situ.
Despite mother nature threatening us with a potential downpour, the day turned out sunny and fine. The exposure of interest was contained in a small area on a gentle grassy slope, so there was plenty of opportunity to sit back and enjoy the warm sunshine.
Thanks to everyone who joined us on the day. We hope you enjoyed it!
