Also known as Red Deer River
Where: Alberta, Canada (50.8° N, 111.5° W: paleocoordinates 58.1° N, 76.0° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Dinosaur Park? Formation (Belly River Group), Late/Upper Campanian (83.5 - 70.6 Ma)
• Hay (1908, p. 94) gave the horizon as: "Judith River deposits, Belly River series, on Red Deer River." Presumably, Hay meant that the deposits were of Judith River age and not that the type came from the Judith River Formation.
•Larson et al. (2012, p. 391–392) note that there is no information on whether the specimen is from the Oldman Formation or Dinosaur Park Formation but suggest that the latter is more likely given that it is more fossiliferous, is exposed over a larger area and collecting has tended to focus on it.
