Stratigraphy
Lithology and environment
| Primary lithology: | marl |
| Includes fossils? | Y |
| Lithology description: The studied gastropods come from a thick marl bed (Facies C of Lazo et al., 2017) correlated among the three sections through lithology, fossil content, and relative stratigraphic position | |
| Environment: | coastal indet. |
| Geology comments: All sedimentological and paleontological evidence suggests a similar setting likely subject to the same depositional processes and comparable environmental fluctuations across the study area. The marl bed represents soft bottoms in a low-energy, possibly lagoonal setting with salinity fluctuating between normal marine and meso-brachyhaline regimes | |
Taphonomy
| Modes of preservation: | body,cast |
| Size of fossils: | macrofossils |
