Stratigraphy
Formation: | Tropic Shale | ||||
Local section: | U1 | Local bed: | 1 (Unit 2) | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Bed horizon is the sample number not the lithologic unit number. The lithologic unit numbers that correspond to the sample numbers given can be found in reference for collection (Elder, 87). |
Lithology and environment
Primary lithology: | burrows,black lithified silty "shale" | ||
Environment: | marine indet. | Tectonic setting: | cratonic basin |
Geology comments: Claystone, slightly calcareous, olive black, poorly indurated. Note: Section U1 constitutes interbedded limestones and shales, but this sedimentary structure is not reflected in the descriptions of each collection, as each is often a single bed, or a portion thereof. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection methods: | bulk,mechanical,field collection |
Reason for describing collection: | paleoecologic analysis |
Collection method comments: Bulk sample disaggregated in lab. |
