Title: Report on Referred Fossils ,  1982 (02/09)
All samples were processed for conodonts in Menlo Park and the heavy-mineral concentrates were submitted for examination for conodonts. The concentrates were futher processed with a magnetic separator and picked in Washington, D.C.

Title: Report on Referred Fossils ,  1980 (10/07)
This report covers four collections from the Permian strata of the Mount Hayes quadrangle. All contain recognizable assemblages that permit correlation with various parts of the Mankomen Group in the A-1 and A-2 quadrangles. The collections are Early Permian in age, with 27355-PC the youngest (probably a Leonardian equivalent). (see also reports by Karklins, dated 2/26/79, and Douglass, dated 4/3/79). The other collections are probably Wolfcampian.
Report by: J. Thomas Dutro , Jr.

Age: Early Permian
Formation: Eagle Creek Formation
Comment:This fossil assemblage and the rock type suggests the lower argillite member of the Eagle Creek Formation (Lower Permian).
