British Triassic fossil reptile sites

摘要: The British Triassic deposits have a broad Ushaped outcrop in the English Midlands, with continuation south-westwards to south Wales and Devon (Figure 4.1). Smaller outcrops occur northwest England, Northern Ireland Scotland (Warrington et al., 1980, figs 2 3). sediments are almost wholly continental ter restrial red-beds deposited fault-bounded basins southern western Britain on more regionally subsiding Eastern England Shelf, which formed onshore marginal part of Southern North Sea Basin (Audley-Charles, 1970; Holloway, 1985). In Late Permian Early Triassic, renewed extensional subsidence Wessex Basin, Worcester Graben Needwood Cheshire basins, resulted establishment an axial drainage system flowed northwards from Variscan Highlands (Holloway,
