tubercles on the specimen. Apparently the name Actinosepia refers to the sharp, spine-like protusions forward of shell at asymptotes. CGS 16395 - Another from 300 ft above base of the Bearpaw. No reason not to call it same thing. Alike in composition. Both rather flat with 3 raised asymptotic ridges - these do not so much mark appreciable change in place of shell a's broad ridges on rather even low arch. Work lateral asymptotes present on both. CGS 16395 shows no tubercles whatsoever; growth lines obscure but seem to project forward, at least along central asymptote, as in 5379. Definitely not the same as the Trail City specimen, being possibility that 2 spec. above represent only the inner layer of the shell. Check this.
