Summary: | During February and March 1969 road excavations in Derryvree townland (H 361390),§ Co. Fermanagh, cut obliquely through a north-east to south-west trending drumlin 2 km north-east of Maguiresbridge (figure 1). The excavations revealed a freshwater deposit of silts and fine sands between two thick and distinct till sheets which formed the drumlin. The organic silts and fine sands contained a flora and fauna of full glacial aspect, which have given a 14 C date of 30 500 +1170 -1030 years B.P. (Birm.166). The flora and fauna indicate that open tundra vegetation and a periglacial climatic régime prevailed in the area at this time. |
