SCARBOROUGH, ENGLAND (June 14, 2015) — It was a drizzly, breezy, cold day on the outcrops, but Team Yorkshire finished measuring and collecting for Meredith Mann’s project on the Passage Beds Member of the Coralline Oolite Formation (Upper Jurassic, Oxfordian) exposed on the north side of Filey Brigg, a spit of rock between Scarborough and Filey. In the posed but useful image above, Meredith stands at the base of the Passage Beds, and Mae holds a meter stick pointing to the top, with the cross-bar on the Thalassinoides unit at the base of the Hambleton Oolite.
We designated five subsidiary units within the Passage Beds, as shown above. The rocks below belong to the Saintoft Member of the Lower Calcareous Grit Formation; the rocks above are the Hambleton Oolite (Lower Leaf) Member of the Coralline Oolite. Note how more ragged this exposure is because it directly faces the sea. The erosion better exposes the stratigraphy and fossils. It also means when we work here we are more subject to the elements.
Meredith and Mae at work collecting rock samples and fossils. We are somewhat protected here from the rain by the overhanging Hambleton Oolite. The wind still blew in plenty of water from sea and sky.
We celebrated completion of our fieldwork by walking as far out on Filey Brigg as we could! Miserable weather, but a dramatic setting! And no one broke a leg on the boulders or was trapped by the high tide.
