The quartz sand deposit Vraniĉ
is located at the foothills of Mt. Papuk close to the
village of Orljavac. At the deposit there was found
numerous fossilized vertabrates which were eroded or
fragmented. Among the well preserved fossils, the majority of which belong to vertabrates (spine bones, rib fragments, and long bones).
Using SEM, barite (BaSO4) was found in specimen which
proves that the bones are from marine environment and that they belong to
marine spine bones. Comparison of the bones with present day animals allowed us to
confirm that the majority of the bones belonged to dolphins and taxonomically
to the Order Cetacea (Whales), Suborder Odontoceti (Toothed Whales), Family Delphinidae
(Dolphins). Further taxonomical classification was not possible. Four
histological samples were taken, and the results confirmed the specimens
belonged to the Order Cetacea. Based on the thumb
bone we completed a reconstruction of the specimen which allowed us to
interpolate its length and weight. The average total length of the specimens is
Numerous other small bone fragments were also found but there determination was not possible. Stratigraphically the fossils were roughly determined as from the Miocene period, most likely stage Badenian.
