Geography

Country:	United States	State/province:	Louisiana	County:	Allen
Coordinates:	30.0° North, 92.0° West (view map)
Paleocoordinates:	31.6° North, 81.0° West

Time

Period:	Paleogene	Epoch:	Eocene
10 m.y. bin:	Cenozoic 2-3
*Period:	Early/Lower Tertiary - Early/Lower Tertiary	*Epoch:	Eocene - Eocene
*Local age/stage:	Clairbornian - Clairbornian
Key time interval:	Eocene
Age range of interval:	56.00000 - 33.90000 m.y. ago
* legacy (obsolete) database fields

Stratigraphy

Geological group:	Wilcox
Stratigraphy comments: Gregory and Hart (1995a, pollen and spores) do not recognize the Clairbornian in the core, but in Gregory and Hart (1995, dinoflagellates), they do. Both papers look at the same samples from the same core and derive different age assignments because they treat each independently. RAL elected to enter a uniform age assignment for both papers.

Lithology and environment

Lithology description: """"50 siltstones and shale samples"""" - individual sample lithology not specified
Environment:	deltaic indet.	Tectonic setting:	passive margin
Geology comments: Although the authors discuss prodelta and delta front as depositional environments, they do not specify explicitly which they choose. The most specific correct entry is thus selected here.

Taphonomy

Modes of preservation:	original chitin,original sporopollenin
Size of fossils:	microfossils

Collection methods and comments

Collection methods:	core,chemical
Reason for describing collection:	paleoecologic analysis
