Stratigraphy
| Geological group: | Honda | Formation: | La Victoria | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "...A level between the Chunchullo Sandstone Beds and the Tatacoa Sandstone Beds..."
Note: This collection had a Friasian age but this must be the Friasian sensu lato, that includes the Friasian sensu stricto, Mayoan and Laventan. La Victoria formation is now considered of Laventan age (Flynn et al., 1997). | |||||
