Geography
| Country: | Ecuador | State/province: | Manabi |
| Coordinates: | 0.2° South, 80.3° West (view map) | ||
| Paleocoordinates: | 0.3° South, 79.9° West | ||
| Basis of coordinate: | based on nearby landmark | ||
| Geographic resolution: | local area |
Time
| Period: | Quaternary | Epoch: | Pleistocene |
| 10 m.y. bin: | Cenozoic 6 | ||
| Key time interval: | Early/Lower Pleistocene | ||
| Age range of interval: | 2.58000 - 0.77400 m.y. ago |
Stratigraphy
| Formation: | Jama | Member: | Punta Ballena | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: While not specified, it appears that the collection is a composite of several bulk samples showing similar taphonomic characteristics and stratal position. Early Pleistocene in age (MOI stages 35-50). The Punta Ballena Member of the Jama Formation is overlain by the El Matal Member (60 m thick, fluvial) and underlain by the Punta Pasa Borracho Member (20 m thick, marine). The Punta Ballena Member is 100 m thick, mixed fluvial and marine. The age of the Jama Formation is constrained by 40Ar/39Ar date of tephra beds. | |||||
Lithology and environment
| Primary lithology: | "cross stratification",medium,coarse,shelly/skeletal unlithified sandstone | ||
| Includes fossils? | Y | ||
| Lithology description: Typically well-sorted trough cross-stratified and medium to very coarse grained shell-rich sands. | |||
| Environment: | shoreface | Tectonic setting: | forearc basin |
| Glacial or sequence phase: | transgressive | ||
| Geology comments: Shallow, high-energy marine environment, nearshore. | |||
Taphonomy
| Modes of preservation: | body,original aragonite,original calcite |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | good |
| Disassociated major elements: | many |
| Temporal resolution: | time-averaged |
| Spatial resolution: | parautochthonous |
Collection methods and comments
| Collection methods: | bulk,sieve,field collection |
| Collection size: | 2823 specimens |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Unknown respository for material; possibly either Universita di Camerino or Universita di Pisa, Italy; faunal list is a composite of multiple bulk collections. | |
| Taxonomic list comments:Exhaustive for Mollusca | |
