Title: Report on Referred Fossils ,  1952 (04/07)
Report by: Bernhard Kummel
Referred by: A. S. Keller , Robert L. Detterman
Age: Carnian
Formation: Shublik Formation
Comment:Lots 23586, 23589, 23590, and 23593 are Karnian in age. The fossils present are related to species found in the Chitistone limestone of the Nizina Valley and to forms reported from the numerous Karnian localities in Alaska including those of the Firth and Canning Rivers, northern Alaska.

The fossils of these lots are nearly all related to species that have previously been recognized from Karnian strata in Alaska. Martin (1916, 1926) and Smith (1927) give complete records of their occurrence in Alaska and western North America.

Collection numbers 15 specimens in total.
