| Age range of interval: | 61.60000 - 56.00000 m.y. ago |
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 |
