Stage:	Ypresian	10 m.y. bin:	Cenozoic 2
*Period:	Early/Lower Tertiary	*Epoch:	Early/Lower Eocene
*Local age/stage:	Wasatchian
Key time interval:	Wasatchian	Zone:	NP 9

Stratigraphy

Formation:	Tuscahoma
Local section:	Wilcx	Local bed:	1
Local order:	bottom to top
Stratigraphy comments: said to be early Wasatchian "near the top" of the formation "beds... almost certainly correlate with marine nannoplankton zone NP 9" the Tuscahoma underlies the Bashi Marl and both are in the Wilcox Group (see Hatchetigbee Bluff)

Lithology and environment

Primary lithology:	glauconitic sandstone
Lithology description: "glauconitic, estuarine channel sand"
Environment:	estuary/bay

Taphonomy

Modes of preservation:	body
Size of fossils:	macrofossils,mesofossils

Collection methods and comments

Reason for describing collection:	taxonomic analysis
Collection method comments: apparently includes omomyid specimen described by Beard and Tabrum 1991, whose stratigraphic provenance was uncertain but believed to be from the overlying Bashi Formation, and which certainly came from the same outcrop
Taxonomic list comments:a total of "some" 25 mammal species are present, hence, the current least is nearly complete
