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.","PeriodicalId":237994,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.

Data on the distribution of corals, composition of the biota as a whole, palaeotemperature and microfacies changes are presented for the first time. The determination of the stratigraphic levels is based on the new and revised biostratigraphic data. The palaeotemperature decline coincides with the maximal flooding surface and is considered as a possible cause of the ecological event triggering the turnover or extinction of many faunal groups. The event level was recognized in the coeval deposits along the Pangea shelves.","PeriodicalId":237994,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.

Clay mineral diagenesis in the Lower Cambrian sediments of the Lontova and Liikati formations in North Estonia, accompanying the main process of illite neoformation, was studied by means of X-ray powder diffraction. Fe-rich chlorite as well as microcrystalline quartz are typically diagenetic byproducts in the clay fraction, formed during illitization. Higher contents of kaolinite and of very fine clay subfraction (< 0.06 pm), consisting of only diagenetically formed minerals, in the silty sediments ofthe Liikati Formation are probably a result of meteoric water influx.","PeriodicalId":237994,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.
