The Panther Mountain Formation
NY Rt.28 between Fly Creek and Cooperstown
This is a small roadside exposure on the north side NY Rt. 20/Rt. 80 between Fly Creek and Cooperstown, Otsego County, NY. The Middle Devonian (Givetian) Panther Mountain Formation of the Hamilton Group is seen here, and is equivalent to the combined Skaneateles and Ludlowville Formations to the west. The sandstone and shale found at this site contain primarily brachiopods and bivalves, often preserved as large numbers of individuals on a bedding plane.
Brachiopods (scale divisions 1 cm)
Cupulorostrum sp. (sappho?)
Spiriferid brachiopods (Mucrospirifer mucronatus?)
Cupulorostrum sp. (sappho?) and Mucrospirifer mucronatus
Bivalves (scale divisions 1 cm)
Left: Leiopteria sp.; Right: Lunulicardium sp.
Left: Nuculoidea sp.; Right: Paleoneilo emarginata
Trace Fossils (scale divisions 1 cm)
Top: two views of a specimen with two unusual intersecting feeding burrows/furrows? This was found in the talus, so its orientation in situ is uncertain. The trace fossil is roughly trapezoidal in cross section. Below: detail of pattern on the side of the "burrow".
