N2 - Cambrian to Lower Ordovician acritarchs and Lower Ordovician conodont species have been recorded from the Furuhall Section at Kopingsklint on Oland, Sweden. The acritarchs are represented by three different microfloras. The first is found at the base of the section investigated and is characterized by the association of Cristallinium cambriense with Eliasum llaniscum, Retisphaeridium dichamerum and R. howellii. The second microflora includes Timofeevia lancarae, T. Pentagonalis and T. phosphoritica and it has been found in layers dated to the Upper Cambrian Agnostus pisiformis trilobite Zone. The third microflora comprises of several species among which Aremoricanium? grootaertii, Athabascaella playfordii, Dasydiacrodium tremadocum, Stelliferidium furcatum which are indicative of a Tremadocian age. The new species Adara denticulata (Middle Cambrian) and Cristallinium aciculatum (Upper Cambrian) are described. The conodont species are referable to Tremadocian Paltodus deltifer Zone and Paroistodus proteus, Prioniodus elegans and Oepikodus evae conodont Zones of the Arenigian. The fauna is typical Baltic, but includes elements of Tropodus comptus and Tropodus sweeti which otherwise are known from the midcontinent conodont faunal province. -from Authors
