Abstract | The chitinozoans from three sections comprising Tremadocian to middle Caradocian strata in Tallinn, northern Estonia, have been investigated. Twenty-eight species of the genera Conochitina, Cyathochitina, Desmochitina, Eisenackitina, Halochitina, Lagenochitina, Rhabdochitina, and Tanuchitina are described. Conochitina critina, C. cucumis, Cyathochitina? clepsydra, Desmochitina papilla, and Tanuchitina tallinnensis are described as new species. The Chitinozoa are compared with those outside northern Estonia and with the type specimens. The chitinozoan palaeoecology is briefly discussed. |
