. Four lateral chitinozoan biofacies, mainly defined by the distribution of Cyathochitina species, are recognized from the uppermost lower Llandovery strata (Coronograptus cyphus age) in 18 eastern Baltic sections. Cyathochitina kuckersiana (Eisenack, 1934) seems to have preferred shallow-water near-shore conditions and С. сайх (Eisenack, 1931) deeper parts of the shelf, whereas C. campanulaeformis (Eisenack, 1931) is more widespread. Representatives of the genus Cyathochitina appear to be absent in most of the near-shore environment. However, these chitinozoan biofacies are probably of only regional significance and occur where calcareous muds (which formed calcilutites) were deposited.

. 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.
