- Abstract
A fossil body was discovered in the Kliwa Sandstone Formation from the Marginal Fold Nappe (= the Vrancea Nappe), in the Tazlău area (Fig. 1). The morphology of this fossil (Fig. 2) and the cuticle ultrastructure (Fig. 3, Plate I) suggest that it belongs to the horny sponges group (Keratosida), leuconoid type, with a wide open osculum (Fig. 4). The presence of the horny sponge in the Kliwa Sandstone Formation (Oligocene) indicates an open marine environment, with a moderate depth and a compact sandy substratum, probably situated below the limit of the storm waves.
