• "60 feet below the Tullock Formation in the northeast quarter of sect. 17, T 22 N, R 43 E"
Lofgren 1995 argues that direct superposition of this locality and Bug Creek Anthills is not demonstrable
based on Lofgren et al. 1990 and Lofgren 1995, fauna is mixed; I have sorted out Paleocene and reworked Cretaceous lists based on Lofgren's scheme
