Stratigraphy
| Local section: | Arrondissement of Mirebalais | ||||
| Regional section: | Montagnes du Trou d'Eau | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Foraminifera similar to assemblages found in the Emperador Limstone of Panama and the Anguilla Formation of Anguilla. Corals also suggest a Late Oligocene-Early Miocene age. Probably correlated to the Culebra and Emperador Fm's of Panama. Stated in text to be Late Oligocene in age, but the authors specifically refer to the Aquitanian stage, and hence an Early Miocene age (Aquitanian) is assigned. Limestone is several hundred metres thick. Rests unconformably upon a basement of schistose limestone. | |||||
Lithology and environment

| Includes fossils? | Y |
| Lithology description: Limestone, gray or yellowish on weathered surfaces and white on unweathered surfaces. | |

Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | poor |
Collection methods and comments
| Collection methods: | selective quarrying,field collection |
| Reason for describing collection: | general faunal/floral analysis |
| Collection method comments: Collected by W.P. Woodring, December 3, 1920. | |
| Taxonomic list comments:Small list of Mollusca, probably not exhaustive, other faunal groups (forams, corals, echinoderms) listed in text if present. Nomenclature antiquated (but should be precise as identified by W.P. Woodring and S.T. Stanton) and often limited to sp. determinations (owing to poor, moldic preservation). Identifications of corals by T.W. Vaughan, Echinoderms by R.T. Jackson, and forams by W.P. Woodring. | |
