Burnham and Welton Chalk Formations, ''Stenotaxis planus ''(38 m) and ''Terebratulina lata ''(60 m) Biozones. Take the B1255 from Flamborough to the Viking Hotel and then follow a rough road to the cafe. Descend the cliff path into Great Thornwick Bay which displays massive-bedded flinty chalk. The flint and marl bands form easily traced marker horizons around the bay and into Little Thornwick, for example the Feruginous Flint (easily recognized by its reddish colour). The Ravendale Flint, 25 m above, is 1 m above the junction of the Welton and Burnham Chalk Formations, and the zonal boundary. Erosion features, excavated along faults and joints, are seen in both bays. Fossils are scarce in the hard recrystallized chalk but include echinoids, brachiopods and bivalves.

Burnham and Welton Chalk Formations, ''Sternotaxis planus ''and ''Terebratulina lata ''Biozones. Take the B1255 from Flamborough to the car park at North Landing (with cafe and toilets). Walk down to the beach via the slipway to the Lifeboat Station. North Landing is a very narrow bay and is probably fault controlled, with the back of the bay choked with till. In summer, boats frequently go out from here to view the birds and pass by the highly contorted chalk at Old Dor and Scale Nab [TA 205 736]. The chalk is massive and flinty, with a marl band forming a prominent ledge dipping into the bay and into the fault line cave on the north side. A band above it contains oysters, brachiopods and the index fossil, ''Sternotaxis planus. ''The flints are very prominent in the bay, especially the 'Paramoudra Flints', large masses up to 1 m length which appear to be original burrows expanded by overfilling with flint.

Return to the car park or take the coastal path back to Bridlington, or north to Speeton via the R.S.P.B. reserve at Bempton [TA 205 736]. '''''None of the coastal sections below Bempton cliffs should be visited even at low tide.'''''
