Stratigraphy comments: middle Lutetian
The CS-41 fossiliferous level is in the uppermost part of the Sobrarbe Formation and has been correlated with nearby sections dated by magnetostratigraphy and benthic foraminifera21, placing CS-41 within the C19r chron and biozone SBZ15 (middle Lutetian, middle Eocene) and making these the oldest sirenian remains in western Europe. |
Lithology and environment
Primary lithology: | mudstone |
Includes fossils? | Y |
Lithology description: CS-41 is a metre-thick level of mudstone, overlying laminated fine-grained sandstones with small burrowing traces. No lamination can be observed in the fossil-bearing bed, but the overlying siltstones present lamination and mud cracks, evidencing subaerial exposure. | |
Environment: | deltaic indet. |
Geology comments: This assemblage is interpreted as the infilling of an intertidal channel during a single energetic event, where all the remains dispersed over the tidal flat were trapped. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Reason for describing collection: | general faunal/floral analysis |
