Sunday 1st September: meet at 10:00. Meet at the car parking area by the ice-cream van at the southern end of Cocklawburn Beach.
Cocklawburn Beach is not only a stunnigly beautiful beach but it also contains a wealth of fossilised ancient life preserved within the layers of rock mapped out across the beach. When these layers of rocks were laid down about 350 million years ago this was a large shallow basin which over hundreds of thousands of years alternated between deltaic sands, mud and swamp and shallow tropical seaa. In these tropical seas there lived a wide variety of sea creatures including crinoids, brachipods, corals, orthocones, fish and trilobites, and their shells and bones in their millions sank to the bottom of the sea to form lime rich layers. Over time these were turned into the hard limestone layers which delimit Cocklawburn Beach and the remains of the sea creatures can easily be found if you know where to look. This walk will take you out onto the limetones shelves and elsewhere in search of fossils along with an explanation of what they were and how they lived.
This walk will be approximately 4 km and will involve some scrambling across rocks on the foreshore.
The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks. Just turn up. A donation will be asked for to cover the costs of the walk, an amount of £10 is recommended, however Northumbrian Earth would like to make these walks accessible to all, so a donation will be asked of whatever you can afford and/or you think the walk is worth.
