Stratigraphy
Formation: | Glen Park | ||||
Local section: | 392 - Horton Creek | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: This member was previously known as the Horton Creek member of the Hannibal Formation. Due to the existence of a paraconformity between the Devonian-Mississippian contact, the exact stratigraphic position of these beds has been corrected several times since these sections were first documented in the early 1900's. Carter contains a complete description of the history of work done on these sections. |
Lithology and environment
Primary lithology: | silty dolomite |
Lithology description: carter states that the fossils are found in only one lithology at each collecting locality, often only in one bed. later in the paper he describes that many of the fossils for stratigraphic locality 392 (horton creek) were found in the silty dolomitic facies. however, in general, the formation is described as containing fossils (brachiopods in particular) in biomicrite, oosparite, silty dolomite or dolomitic limestone, and calcareous sandstone or arenaceous limestone. | |
Environment: | shallow subtidal indet. |
Taphonomy
Modes of preservation: | body |
Collection methods and comments
Collection excludes: | some macrofossils |
Collection methods: | survey of museum collection |
Reason for describing collection: | taxonomic analysis |
Collection method comments: This collection is a Carnegie Museum of Natural Hisory collection. | |
Taxonomic list comments:Although molluscs are abundant at the type section of the formation and other macro invertebrates are very rare, only the brachiopod data are reported in this list. |
