Snowdonia would not the first venue that springs to mind if you wanted to go fossil hunting, there are much easier pickings to be had on the beaches of Dorset and Yorkshire than in these ancient mountains. This does however, make it all the more rewarding when you do come across fossils here.
I was lucky enough to be out in the Glyderiau with an ML assessment group recently and we were heading into some steep terrain off the beaten track. We stumbled upon a bed of sandstone sandwiched between volcanic rocks and in the sandstone we found several fossils. The fossil are Brachiopods, simple sea dwelling invertebrates. These particular ones are trapped in the Cwm Eigiau sequence of rocks which date from the Ordovician period meaning they lived on the sea bed 450 million years ago, today they are about 800 metres above sea level on a north facing slope in the Glyderiau. Happy fossil hunting!
