Title: Report on Referred Fossils ,  1969 (12/05)
This report covers hornfelsic-appearing limestone with spaghetti structure.
Report by: C. W. Merriam
Referred by: Henry C. Berg
Age: Silurian-Devonian
Comment:Smoothed surfaces of this altered limestone show that the spaghetti structure is probably that of a slender Cladopora, Coenites or a related type of favositid. It is conclusively not Amphipora. This rock could well be somewhere in the range of Silurian to late Middle Devonian.
