Saturday 27 June 2009
Aust Cliff and Manor Farm, South Gloucestershire
Field leader: Simon Carpenter
Aust Cliff and Manor Farm are geological sites of national and international importance. Both localities expose rocks of Upper Triassic age (approximately 210 million years old) - with plentiful fossils. Of particular interest is the bone bed, containing a profusion of teeth and bones of marine reptiles and fish. The rocks also contain abundant invertebrate fossils including bivalves and many trace fossils - all of which are beautifully preserved. Simon will explain how these rocks were formed and using fossils from his own collection, describe some of the spectacular animals that once lived during this period. Following our visit to Aust Cliff, we will have lunch at the Boars Head in Aust village or alternatively bring a packed lunch. The afternoon will be spent at Manor Farm - a short distance inland from the Aust Cliff section.
Meeting: 10:30am at the old Aust ferry crossing, Old Passage ST 564889. Old Passage is located West of Aust and close to the banks of the River Severn estuary. Please bring hard hats and wear boots as both localities can be very muddy. Contact Bristol Naturalists' Society.
