Name Wallington limestone suggested for limestone formerly regarded as Reynales at Rochester and eastward. Thickness at type section 15 ft. Younger than type Reynales of Niagara and Orleans Cos. and separated stratigraphically from it by Furnaceville hematite. Underlies lower Sodus shale. Age is Middle Silurian (Ontarian).

Wallington Member of Reynales Limestone consists of about 4.0 to 6.0 m of dolostone, commonly cherty brachiopod/crinoid pack- and grainstone, pelletal grainstone, and greenish gray shale. Base of the Wallington is defined at the base of a phosphate granule-bearing thin grainstone bed that overlies the Seneca Park Bed (new) of the Brewer Dock Member. Similar in lithology to the underlying Brewer Dock Member and can be divided into about six carbonate-to-shale cycles. Uppermost cycle thins eastward and merges into the Sterling Station Hematite of Gillette (1947) that marks the top of the Reynales and equivalent Bear Creek Shale in Wayne and Oswego Cos. Westward from Genesee Gorge, outcrops become infrequent. At Lockport the entire Reynales is assigned to the Hickory Corners Member, though the strata there are equivalent to the Brewer Dock Member and the lower 120 cm of the Wallington. Unconformably(?) underlies the Sodus Shale.
