Latest Silurian (Ohesaare Stage) conodonts and the detorta Zone in the northern East Baltic

Abstract

The latest Silurian conodonts from the Sorve Peninsula of Saaremaa Island, Ruhnu Island, and western Latvia include Ozarkodina remscheidensis remscheidensis, Oz. confluens, Oz. nasuta, and Oulodus elegans. They represent the local nearshore remscheidensis remscheidensis Subzone of the remscheidensis Zone. The Oulodus elegans detorta Zone occurs as a short interval in the upper part of the Ohesaare Stage. Three new species are described: Amydrotaxis? praecox, Oz. denticulata, and Oz. inordinata. Ozarkodina nasuta (Viira, 1983) was originally described as the subspecies of Oz. confluens.
