Title:	Report on Referred Fossils , 1967 (11/01)

Report by:	Norman J. Silberling
Referred by:	Donald H. Richter


Age:	Norian






Comment:	The pelecypod Monotis subcircularis Gabb dates this collection as late Norian (late, but not latest, Late Triassic) in age. Also present in the collection are terebratuloid brachiopods which add nothing to the age assignment. The excess material and matrix from this collection are being returned to Richter as requested.
