Coordinates: | 31.6° North, 93.6° West (view map) | ||||
Paleocoordinates: | 35.5° North, 75.2° West | ||||
Basis of coordinate: | based on nearby landmark | ||||
Altitude: | 270 feet | ||||
Geographic resolution: | outcrop |
Stratigraphy
Geological group: | Midway | Formation: | Logansport | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: JAS has updated the age of this collection. "Logansport" was noted as a preoccupied name by Palmer and Brann (1965), who instead used the name "Halls Summit". |
Lithology and environment
Primary lithology: | concretionary lithified calcareous claystone |
Includes fossils? | Y |
Lithology description: Fossils occur in septarian calcaerous concretions within either siltstone or claystone background sediments. | |
Environment: | offshore |
Geology comments: No paleoenvironmental data stated. Appears to be a shallow shelfal environment. Enterer has designated it as "offshore siliciclastic". |
Taphonomy
Modes of preservation: | body,concretion |
Size of fossils: | macrofossils,mesofossils |
Collection methods and comments
Collection methods: | field collection |
Reason for describing collection: | biostratigraphic analysis |
Collection method comments: Collected by LaBlanc and Barry (1939); a short distance from locality Harris (1899) reported fossils from. | |
Taxonomic list comments:Antiquated nomenclature. Reviewed by LaBlanc (1942), and some names are validated by Toulmin (1977). |
