*Local age/stage:Friasian
Key time interval:Laventan

Stratigraphy
Geological group:Honda Formation:La Victoria
Stratigraphic resolution:group of beds
Stratigraphy comments: "About 50 m stratigraphically above the Chunchullo 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).
Lithology and environment
Primary lithology:pebbly,volcaniclastic,gray sandstone
Secondary lithology:ferruginous,shelly/skeletal,gray,green,red mudstone
Includes fossils?Y
Lithology description: The La Victoria Formation has "coarse- to fine-grained pebbly lithic arenites with important amounts of volcanic fragments and plagioclase alternating vertically and laterally with reddish-brown and greenish-gray mudstone. The mudstones are very rich in fossil vertebrates"
Environment:fluvial indet.
