Paleogene Dasycladalean algae from the north-east foot of Biokovo Mt. (Dinarides Mts., Croatia)
Previous findings of Paleogene dasycladalean algae in the coastal area of the Karst Dinarides include those from the island of Korčula (Radoičić, 1974, 1995), Pelješac peninsula (Radoičić, 1995) and Konavle area near Dubrovnik (Radoičić, 2004). On the north-east foot of Biokovo Mt. near Kozica village Paleogene strata lay trasgressively onto the Upper Cretaceous strata. Several samples from the lower part of Paleogene contain numerous specimens of dasycladalean algae. Preliminary investigations indicated fossil association quite similar to one described by Barattolo (1978) and Barattolo & Romano (2002) with addition of some previously unknown forms. One group of specimens comprises relatively small algae with thin calcareous skeleton and clearly separated whorls of floiophorous branches. Among them species Clypeina bucuri BARATTOLO & ROMANO and Clypeina lucana BARATTOLO & ROMANO have been determined. New findings of these algae add some new data on their morphology, which ease their mutual discrimination. Another group of specimens comprise large algae with articulated calcareous skeletons and whorls with differently inclined floiophorous branches. Despite very good preservation of fossil material, it is very difficult to interpret the position of branches as the result of their origin from the same tuft of branches (metaspondylity) or as the result of different inclination of branches from the same whorl (euspondility). Three species can be distinguished in investigated material. One is already known Praturlonella salernitana BARATTOLO and other two are new species assigned to the genus Falsolikanella GRANIER. Generic determination, due to the mentioned doubt on the position of the branches, should remain uncertain.
