Geography
Country:Haiti
Coordinates: 18.9° North, 72.0° West (view map)
Paleocoordinates:20.4° North, 67.0° West (Wright 2013)
Time
Period: Paleogene - Neogene Epoch: Oligocene - Miocene
Stage: Rupelian 10 m.y. bin: Cenozoic 4 - Cenozoic 5
Key time interval: Early Oligocene - Middle Miocene
Age range of interval: 33.9 - 11.63 m.y. ago
Stratigraphy
Formation:Maissade
Stratigraphy comments: On the general correlation table these sediments are shown in part as Oligocene and Miocene to correspond with Maury's determinations in the Yaqui Valley of Santo Domingo. What is here called the Maissade is undoubtedly the equivalent of the Sconsia laevigata and the Aphera islacolonis formations in Maury's section' and the equivalent in part of Hill's Bowden in Jamaica. This places the Maissade in the Miocene and it represents probably lower and middle Miocene. PJW: This represents lignite deposits that occur in three different formations.
Lithology and environment
Primary lithology: poorly lithified sandy "shale"
Includes fossils?Y
Lithology description: Pieces of the shale lay about the base of the bluff and from these pieces the species were collected, lignite fragments also imbedded in sand
Environment:coastal indet.
Geology comments: The exposure is a bluff on the east of the river and consists largely of shale beds dipping east at low angles.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:general faunal/floral analysis
