Stratigraphy
| Formation: | Rosso Ammonitico Veronese | Member: | Lithozone 5 | ||
| Stratigraphy comments: Middle Rosso Ammonitico Veronese (upper Callovian-middle Oxfordian)
The fossil reptile described herein was collected from the upper cherty deposits of the MRAV (Lithozone 5 of Martire et al. 2006; Fig. 1B), which ranges in age from the uppermost Callovian to the middle Oxfordian |
Lithology and environment
| Primary lithology: | nodular calcareous,cherty/siliceous mudstone |
| Includes fossils? | Y |
| Lithology description: All preserved elements were removed from a nodular and cherty interval of the exposed Middle Unit of the Rosso Ammonitico Veronese Formation (Middle-Upper Jurassic; sensu Martire et al. 2006)...This interval is characterized by the abundance of nodules and lenses of red chert, resulting in an irregular bedding style. Limestones are wackestones to packstones with common radiolarians and sponge spicules and minor thin-shelled bivalves. | |
| Environment: | carbonate indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils,some microfossils |
| Collection methods: | selective quarrying,survey of museum collection |
| Reason for describing collection: | taxonomic analysis | Collection dates: | 1980s |
| Collection method comments: MPPL, Museo Paleontologico e della Preistoria “Pietro Leonardi”, Ferrara, Italy. | |
| Taxonomic list comments:Besides the plesiosaurian bones, the other fossil remain found in the quarry were small and isolated shark teeth, possibly belonging to scavengers of the carcass
