| Age range of interval: | 72.10000 - 66.00000 m.y. ago |
Stratigraphy
| Geological group: | Great Valley | Formation: | Moreno | Member: | Marca |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: There is uncertainty on the boundary between the Moreno and Panoche Formations in the area. Stock (1941) reported the specimen was found in strata 150 ft. below the Siphagenerinoides zone, however this zone has been referred to the Moreno Formation and the Panoche Formation by geologists. Considered to come from upper part (Marca Mb.) by Bell & Evans 2010. | |||||
