Stratigraphy
| Formation: | Coli Toro | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Author debates the possibility of this being "Danian" (= Early Tertiary), and thus a report of a genuine Cenozoic dinosaurs. Currently considered to be Late Cretaceous. Formation is not named in the paper; it may be the Allen Fm. Also spelled "Cali-Toro Formation" and "Colitoro Formation"
