Stratigraphy
| Formation: | San Martino Calcarenite | ||||
| Local section: | Torrente Meduna | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Miocene Torento-Meduna sequence unconformably overlies the Eocene Clauzetto Flysch (Flysch di Clauzetto) and is composed of Preplans Sandstone, Zouf marl, Rugo Mizza Sandstone, San Martino Calcarenite, Torrente Meduna Siltstone, Maraldi Sandstone, Bier Puddingstone, and Montello Conglomerate. Thickness of the San Martino Calcarenite is approximately 170 m. Sample 11 is from the uppermost part of the San Martino Calcarenite. | |||||

| Primary lithology: | medium,coarse,micaceous,brown,gray sandstone |
| Includes fossils? | Y |
| Lithology description: San Martino Calcarenite "consists of medium to coarse-grained, brown-gtrey, micaceous sandstone". | |
| Environment: | offshore |
| Geology comments: "Rich foraminiferal assemblages suggest a Langhian age". | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | all microfossils |
| Collection methods: | bulk,field collection |
| Collection size: | 24 specimens |
| Rock censused: | 30 cm3 (volume) |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Based on single bulk samples, about 30 cubic centimetres each. Grain size data also provided. | |
| Taxonomic list comments:In enterers opinion the taxonomic list is representative of molluscan taxa, however no non-mollusca taxa are detailed. The reference states "Fossil content includes rare megafossils and rich formaniferal assemblages". | |
