Stratigraphy
Geological group:Hawthorn Formation:Peace River Member:Bone Valley
Stratigraphy comments: Peace River Formation in Florida was likely deposited between 11-4.3Ma. The lower sequence is Tortonian, deposited between 11-8.5Ma, and the upper sequence is Zanclean and deposited between 5.2-4.3Ma (Missimer, 1999)
Lithology and environment
Primary lithology: not reported
Environment:terrestrial indet.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some genera
Reason for describing collection:taxonomic analysis
Taxonomic list comments:according to Hulbert 1988c, "Hippotherium cf. occidentale" and Hipparion cf. tehonense are present but were not found in situ
material of "Cormohipparion emsliei" reported by Hulbert 1988b apparently is from a younger horizon elsewhere in the mine
lists used from 1993 - 2000 included the following unreferenced taxa: Teleoceras sp., Aelurodon sp., Barbourofelis sp., Camelidae indet., and a "gelocid"; these apparently are not discussed in any publication, and the list may have been given in a c. 1989 personal communication from Hulbert that was lost around 1990
