About the event

Join Andy at East Quay, Watchet for a short walk over to Helwell Bay - a fantastic opportunity to examine the creatures that inhabited the shallow seas that covered West Somerset in the early Jurassic period, approximately 200 million years ago. The superbly exposed sequence of marine limestones and mudstones are highly fossiliferous, ammonites are particularly common. The extensive foreshore reef exposures also enable a 3D picture of communities living on the early Jurassic sea floor to be reconstructed, including giant burrowing worms and 'Nautilus islands'. Another special feature seen at Helwell Bay is the structural effects of the Watchet Fault which has a vertical displacement of over a quarter of a kilometre at this location and juxtaposes some of the oldest Triassic aged rocks against the youngest Jurassic strata exposed on the west Somerset coast, before heading inland and linking with the western scarp slope of the Quantock Hills.
