Lithology and environment
| Primary lithology: | "carbonate" |
| Lithology description: Zoboli et al. 2019: An epiclastic pomiceus-cineritic level underlies silicified lacustrine carbonates of the lower part of the Perfugas Formation (Sowerbutts, 2000). This fossiliferous epiclastic level is divided into three different layers, the majority of the vertebrate remains coming from the top of the lower layer (Zoboli and Pillola, 2017b; Mennecart et al., 2019). | |
| Environment: | lacustrine indet. |
| Geology comments: Zoboli et al. 2019: In the Anglona subregion, the lower part of the Perfugas Fm. comprises continental lacustrine deposits represented by finely bedded limestones and tuffs (Sowerbutts, 2000). | |
