Stratigraphy
Lithology and environment
Primary lithology: | argillaceous,silty claystone |
Secondary lithology: | fine,concretionary,micaceous,shelly/skeletal,gray silty,calcareous sandstone |
Includes fossils? | Y |
Lithology description: silty, fine sandy clay, medium sandy clay, silty clay, (several units with varying amounts of silt, sand and clay in each). Unit bearing vertebrates is "Clayey fine sand and silty clay, micaceous, lignitic, very fossiliferous, olive-gray (5 Y 3/2). Calcareous, sandy concretions abundant throughout unit. Zones of molluscan hash locally present. Prominent erosional horizon in lower meter, traceable throughout exposure, features abundant vetebrate bones and teeth, and very-large-oyster bioherm. " | |
Environment: | transition zone/lower shoreface |
Taphonomy
Modes of preservation: | body,trace,replaced with phosphate |
Size of fossils: | macrofossils,microfossils |
Articulated whole bodies: | some |
Disassociated minor elements: | some |
Collection methods and comments
Collection excludes: | all macrofossils,some genera |
Collection methods: | field collection |
Reason for describing collection: | taxonomic analysis |
Taxonomic list comments:IHay (1908) reviewed the systematics of the Peritresius ornatus, and included a description that had been reported by Cope (1878). This turtle almost certainly came from this locality. Cope collected other material from the Blufftown for which exact locality information is not available. |
