Four species of the genus Boltovskoyella Malumián & Masiuk are recognized in Patagonia, among them, B. paleocenica sp. nov., which is described from Danian shallow marine sediments. Considering that the previous records of Boltovskoyella are from the Middle-Late Eocene, this new species represents the oldest known occurrence of the genus. Boltovskoyella seems to be endemic to Patagonia, shows opportunistic features and prefers temperate-warm water settings.
