Coordinates: 42.3° North, 0.1° East (view map)
Paleocoordinates:39.1° North, 2.9° West
Basis of coordinate:estimated from map
Period:Paleogene Epoch:Eocene
Stage:Lutetian 10 m.y. bin:Cenozoic 2
Key time interval:Lutetian
Age range of interval:47.80000 - 41.30000 m.y. ago
Stratigraphic resolution:formation
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.
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Reason for describing collection:general faunal/floral analysis
Also known as:Castejón de Sobrarbe-41 fossil site (CS-41)
