Stratigraphy
| Formation: | Rugo Mizza Sandstone | ||||
| 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 Rugo Mizza Sandsone is approximately 215 m. | |||||
Lithology and environment
| Primary lithology: | glauconitic silty marl |
| Includes fossils? | Y |
| Lithology description: Rugo Mizza Sandstone is "composed of fine-grained greyish sandstone, with rare intercalations of silty clay. The upper part consists of silty marl topped by the glauconitic bed." | |
| Environment: | offshore |
| Geology comments: "Microfaunas point towards a Burdigalian age; the glauconitic bed was considered to be of Langhian age by Stefani (1982) [this is not what is illustrated in current reference]" | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils,difficult macrofossils |
| Collection methods: | bulk,field collection |
| Collection size: | 7 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 and the reference indicates "Megafauna is concentrated mainly in the upper part and includes bivalves, ahermatypic corals and echinoid fragments; abundant burrows occur as well". | |
