Abstract
A “New Red Sandstone” sequence has been known near Kingscourt, Co. Cavan, ever since the work of Griffith1, although in the absence of any palaeontological data its age has always been uncertain. It occurs 25 km west of Dundalk Bay in a narrow lenticle some 14 km long orientated north-south that is downfaulted athwart the Lower Palaeozoic Longford-Down massif. A palynological study, linked with a re-evaluation of the lithostratigraphy, has revealed that the sequence shows marine-continental transitions and embraces the Permian-Triassic boundary.
