Quantitative comparisons have been made of samples from different positions in the deposit, but they show little variation from the single set of results given below in Figure 5. Towards the edge of the Bee's Nest plant bed, the number of fossiUferous pieces of clay suddenly diminishes without apparent bedding changes, to be completely replaced by the pale grey clay matrix (Fig. 2).

. Bulletin of the British Museum (Natural History), Geology. NEOCENE PLANT BEDS 393 deposition of a continuous nature. Quantitative comparisons have been made of samples from different positions in the deposit, but they show little variation from the single set of results given below in Figure 5. Towards the edge of the Bee's Nest plant bed, the number of fossiUferous pieces of clay suddenly diminishes without apparent bedding changes, to be completely replaced by the pale grey clay matrix (Fig. 2). The plant bed at Kenslow Top pit is exposed for some 25 metres at the working Fig. 2. Postulated section across the plant bed at Bee's Nest pit, Brassington. The plant bearing clay (stippled) is in the form of small blocks up to 100 mms. across, mixed into pale grey unfossiliferous clay (diagonal lines). The bedding of the underlying sands and clays (solid black) is folded to form a geosynclinorium. Before excavations began, the bed was covered with 2-3 metres of glacial till (dotted lines). The figure is not drawn to scale ; at present, about 9 sq. m. of plant bed is Fig. 3. Postulated section across the plant bed at Kenslow Top pit, Friden. The plant bearing clay (stippled) is in the form of a plano-convex lens, about 6 m. wide and 3 m. thick at the centre. At the lower edge of this block small pieces of plant bearing clay are mixed in with pale grey unfossiliferous clay (diagonal lines). The bed is covered with 2-3 metres of glacial till (dotted lines)..
