Geography
| Country: | Panama |
| Coordinates: | 9.1° North, 80.0° West (view map) |
| Paleocoordinates: | 9.0° North, 79.0° West |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Messinian | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Messinian | ||
| Age range of interval: | 7.24600 - 5.33300 m.y. ago |
Stratigraphy
| Formation: | Chagres Sandstone | Member: | Toro Limestone | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: From Olsson's Anomia zone limestone. Chagres Sandstone overlies and partly overlaps the Gatun Fm. Calcareous strata at the abse of the formation throughout most of the outcrop area in the Canal Zone constitute the Toro Limestone Mbr. The unit is as much as 1000 ft thick. AGE: Late Miocene (late Tortonian-Messinian) according to Collins and Coates 1999); Messinian age is more probable. | |||||
Lithology and environment
| Primary lithology: | "cross stratification",medium,coarse,shelly/skeletal poorly lithified sandy "limestone" |
| Includes fossils? | Y |
| Lithology description: Calcareous deposit consisting principally of lime-cemented coquina made up of small fragments of barnacles, shells, echinoid spines, and corals; cross-bedding common; lenses of medium-coarse-grained sandstone occur in the coquina. | |
| Environment: | shallow subtidal indet. |
| Geology comments: No specific environmental data presented. | |
Taphonomy
| Modes of preservation: | body |

Collection methods and comments
| Collection methods: | selective quarrying,field collection |
| Reason for describing collection: | taxonomic analysis |
| Museum repositories: | CAS,PRI,USNM |
