Description

The Calcare di Cellina comprises a limestone facies corresponding to the peritidal successions of the inner part of the Periadriatic carbonate platforms. The layer in which the tracks were found is characterized by intertidal muds which were later covered and sealed by a transgressive subtidal layer, representing a moderately more open but low energy environment. Most of the limestone blocks show similar lithofacies, with bed thickness exceeding a metre, the presence of occasional stylolites and rare requienids; the bed surfaces present mud cracks, bioturbation due to burrowing organisms and pedogenetic breccias (sometimes with black pebbles). The color ranges from whitish through light brown to pale pink. The blocks sometimes present desiccation structures (mud cracks, birdseyes) and mostly comprise muddy facies, often with ostracods. In contrast, the level with the footprint is a fossiliferous wackestone (with foraminifers and ostracods), with no traces of subaerial exposure.
