Collectively, this is almost the same assemblage as USGS 7981-SD with which you related it on field evidence. The one addition is a single rugose coral that is probably Temnophyllum sp. The genus Temnophyllum ranges from Eifelian (rare) through Givetian and Frasnian.

In my Professional Paper evaluation of the Jade Mts. Limestone-dolomite unit corals, I concluded that they were of Early or Middle Devonian age with Middle being more likely. This new Temnophyllum? supports a Middle Devonian age for the whole coral assemblage but if age differences between collections are allowed, some could be Early and others Late Devonian.

Collection 73ATr84.1 contains no recognizable corals. Three tubular or branching specimens are completely recrystallized. They could be thamnoporoid corals, bryozoans, stromatoporoids or inorganic in origin.

Possible brachiopods in 82.2 and 84.1 will be shown to Tom before being discarded.
