Stratigraphy
Formation:Cerrejón
Stratigraphic resolution:bed
Lithology and environment
Primary lithology: lithified silty,sandy "siliciclastic"
Lithology description: We collected fossil leaves and fruits from six lens-shaped, siltstone/sandstone bodies with inclined heterolithic strata that suggest deposition in low-energy channels. Ten other localities preserve leaves in thin but tabular beds of flat- laminated siltstone that indicate deposition in small lakes. The megafloral local- ities occur from 100 –750 m above the base of the formation
Environment:"channel"
Taphonomy
Modes of preservation:adpression
Size of fossils:macrofossils,mesofossils,microfossils
Temporal resolution:time-averaged
Collection methods and comments
Collection methods:bulk,selective quarrying,mechanical,field collection
Reason for describing collection:paleoecologic analysis
