A NEW UPPER SILURIAN CONODONT SPECIES FROM ESTONIA

Abstract

. A new conodont species Ozarkodina roopaensis sp. n. is described from the Ludlow-age Roopa cliff of the Paadla Formation, corresponding to the uppermost part of the Gorstian Stage. The O. roopaensis conodont Zone represents part of the Ludlow nearshore zonation scale in the East Baltic. The new species of Ozarkodina is related to Ozarkodina confluens, but differs in Pa element having primitive transverse ridges on oral smooth surfaces of denticles. Characteristic is the distribution of white matter.
