Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: said to be early Hemphillian, Hh2
sinkhole is "developed in the Inglis member of the Ocala Limestone (Late Eocene)" (Becker 1985) |
Lithology and environment
Primary lithology: | fine,green silty claystone |
Lithology description: "fine green clays, with some evidence of layering or varving" that fill "a sinkhole" (Becker 1985) or "massive green clays and occasionally concentrated in thin beds of silt" | |
Environment: | pond |
Geology comments: "a pond environment" but there "is some [faunal] evidence for marine or estuarine influence" (Becker 1985) or "a freshwater pond or oxbow lake cut" (Webb 2008) |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Spatial resolution: | autochthonous |
Collection methods and comments
Reason for describing collection: | taxonomic analysis |
Museum repositories: | FLMNH |
Collection method comments: Eocene, Hemphillian, and Rancholabrean fossils are all present but easily distinguished based on preservation and color | |
Taxonomic list comments:Site 4A is in Marion Co., site 4X in Citrus Co.: Webb 1989 |
