Geology comments: "A series of carbonate debris flows [into basinal shales] derived from the platform margin is preserved in this area. It is from these gravity flow deposits that silicified fossils have been recovered."
Taphonomy
Modes of preservation:body,replaced with silica
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Reason for describing collection:taxonomic analysis
Taxonomic list comments:Odontopleurinae trilobites only; article implies there is a graptolite fauna as well.
