Dynamic Coast - a geological look at Watchet
Time & Location
About the Event
Join Andy at Helwell Bay, Watchet - a fantastic opportunity to examine the creatures that inhabited the
shallow seas that covered west Somerset in the early Jurassic period, 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.
Combine this walk with a chance to visit the new East Quay Art Gallery, Watchet and see “SHIFT – Somerset’s Brilliant Coast” – an art exhibition supported by Somerset Wildlife Trust and Contains Art.
