Geography
| Country: | United States | State/province: | New Mexico | County: | Bernalillo |
| Coordinates: | 35.2° North, 107.0° West (view map) | ||||
| Paleocoordinates: | 40.1° North, 75.1° West | ||||
| Basis of coordinate: | stated in text | ||||
| Altitude: | 1788 meters | ||||
| Geographic resolution: | small collection |
Time
| Period: | Cretaceous | Epoch: | Late/Upper Cretaceous |
| Stage: | Santonian | 10 m.y. bin: | Cretaceous 6 |
| Key time interval: | Early/Lower Santonian - Middle Santonian | ||
| Age range of interval: | 86.30000 - 83.60000 m.y. ago |
Stratigraphy
| Formation: | Point Lookout | Member: | Hosta | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: ca. 6.5 m below local top of the Hosta Tongue. Bone bed in a ~0.5 cm-thick interval. The age of the Hosta Tongue of the Point Lookout Sandstone is well constrained as Santonian by stratigraphically-bracketing ammonoid assemblages (e.g., Molenaar, 1983). However, few ammonoid data have been published from the Hosta Tongue in New Mexico to determine a more precise age within the Santonian. Varriale (2003) reported Clioscaphites saxitonianus (McLearn) and Cladoceramus undulatoplicatus (Roemer) from the Hosta-Dalton sandstones in the Galisteo region in Santa Fe County. These two taxa indicate an early Santonian age. Molenaar (1983) noted the occurrence of Texanites texanus (Roemer) in the Hosta Tongue in the southern San Juan Basin and considered it middle Santonian because it indicates the zone of Clioscaphites vermiformis (Meek and Hayden). Therefore, we consider the Hosta Tongue of the Point Lookout Sandstone at NMMNH locality 297 to be early to middle Santonian in age. | |||||
Lithology and environment
| Primary lithology: | poorly lithified sandstone |
| Includes fossils? | Y |
| Lithology description: Buff sandstone of the Hosta Tongue of Point Lookout Sandstone. Massive sandstone with laminar sandstone in vicinity. | |
| Environment: | paralic indet. |
| Geology comments: In general, the paleoenvironment of Hosta deposition was a paralic setting in which sand accumulated along the shoreline of the Western Interior Seaway (e.g., Molenaar, 1983). Thus, paleoenvironments ranged from fluviodeltaic to offshore sandbar. The paleoenvironment at locality 297 was likely that of a “beach” in which freshwater and marine fossils were mixed. Interpreted as a basal channel lag | |
