PHYTOPLANKTON (ACRITARCHS) FROM A SMALL ORDOVICIAN INLIER IN TEESDALE (COUNTY DURHAM), ENGLAND

Abstract
Summary: Several hundred acritarchs have been recovered from two samples of Skiddaw Slates of the Teesdale Inlier. The assemblages are dominated by trispinose veryhachiids, but altogether thirteen species have been recognized, attributable to three acanthomorph genera— Archaeohystrichosphaeridium, Baltisphaeridium and Micrhystridium —the polygonomorph genus Veryhachium, the diacromorph genus Acanthodiacrodium and to the sphaeromorph genus Leiosphaeridia. A lower Ordovician age is confirmed and equation with the Milburn Beds of the Cross Fell Inlier is suggested.
