Large deep burrowing bivalves in Middle Miocene (Badenian) of Central Paratethys ; examples from Northern Croatia

Bivalve genera Panopea and Pholadomya represent rarely documented large deep burrowers found within Miocene coralline algal facies of Northern Croatia. Two localities are investigated, situated in marginal part of the Medvednica Mt. and in the Zrinska Gora Mt. Both genera, Pholadomya and Panopea, represent infaunal, siphonate, suspension-feeding, relative immobile deep burrowing bivalves, with similar palaeoecological demands, sharing their habitats during the Miocene epoch. The aim of this study is to document the presence of bivalve genera Pholadomya and Panopea in their life position in the Middle Miocene (Badenian) sediments of the Medvednica Mt. and finding of the largest found specimen of Pholadomya bivalve in the Zrinska Gora Mt. This study provides an insight to the findings of these infaunal bivalves in Croatia and worldwide, their palaeoecological features and their similarities and differences regarding their reproductive activity and abundance in Miocene and recent sediments.
