Geography
Country: | Mexico | State/province: | Tamaulipas |
Coordinates: | 23.8° North, 99.3° West (view map) | ||
Paleocoordinates: | 25.6° South, 76.0° West | ||
Geographic resolution: | small collection |
Stratigraphy
Formation: | Canon de Caballeros | Member: | Santa Ana Limestone | ||
Stratigraphic resolution: | member | ||||
Stratigraphy comments: The authors indicate that the Santa Ana Member may be diachronous, as to the N some taxa there indicate an age of late Llandovery. They feel that it isn't diachronous, just the age determination needs more work. |
Lithology and environment
Primary lithology: | shelly/skeletal lithified grainstone |
Lithology description: distinctive bioclastic grainstone commonly with abundant coarse grains and granules of polycrystalline and monocrystalline quartz. | |
Environment: | sand shoal |
Geology comments: "The fauna from the Santa Ana at loc. JS93-88 represents a rough water Pentamerus community assigned to BA3. Dominance of Atrypa in Stinnesbeck collection...indicates a discrete ecological setting although BA3 is likewise indicated." |
Taphonomy
Modes of preservation: | body |
Collection methods and comments
Collection methods: | field collection |
Reason for describing collection: | biostratigraphic analysis |
