| Key time interval: | Early/Lower Turonian - Middle Turonian | Ammonoid zone: | Mammites nodosoides or Collignoniceras woollgari |
| Age range of interval: | 93.90000 - 89.80000 m.y. ago |
Stratigraphy
| Stratigraphy comments: "Upper Greenhorn Limestone or lower Fairport Chalk Member. If this assessment is correct then the specimen is Middle Turonian in age" (Schumacher & Evrhart 2005).
Mammites nodosoides or Colligniceras woollgari ammonite zones according to Schumacher (2011), so Early-Middle Turonian |
