Summary:
Author refutes age assignment of Rigby (1991: Journ. Paleont, v. 65, no. 1) who considered the Hungry Hollow of southwestern Ontario to correlate with the Centerfield Limestone Member of the Ludlowville Formation of NY. The unit had long been correlated with the Prout and Ten-Mile Creek Formations of north-central and northwestern OH. Based on conodonts recently recovered from the Prout it appears that the Hungry Hollow is more likely correlative with the Tully Limestone of NY, which is well above the Ludlowville. Age, then, is here considered Givetian (Middle Devonian).
