| Taxonomic list comments:said to be unambiguously Cretaceous as a "partially articulated dinosaur skeleton was discovered in 1979 at the same horizon several hundred meters to the east"; however, fauna appears to be mixed and may be in a channel fill laterally equivalent but younger than the skeleton; Lofgren 1995 voices similar doubts, and I have used his criteria to separate Paleocene and reworked Cretaceous lists possible Paleocene records: Mesodma sp. Cimolestes cf. incisus Storer 1991: "C. cf. cerberoides" list repeated by Fox 1990. BUT Fox 1997 claims it is not reworked. | |
