Locality 85JTP07
The sediments exposed here belong to the lower part of the Upper Killik Tongue of the Chandler Formation (Chapman et al., 1964), now the upper part of the Nanushuk Formation of Mull et al. (2003). The section on the west bank of the Colville River is poorly exposed. Material was mostly collected as float. Fine-grained sandstones yielded highly fragmented, poorly sorted plant materia. Recognizable remains are predominantly those of Podozamites, Sphenobaiera, Ginkgo, Pityophyllum ex gr. nordenskioldii, Athrotaxopsis, Elatocladus, Cephalotaxopsis and Sphenopteris.
