Summary:

Pg. 797, 803 (fig. 3), 807-808, 811-812, 813. Gailor dolomite. Because OPHILETA, HELICOTOMA(?) UNIANGULATA, and ECTENOCERAS are exclusive Canadian index fossils, the latter two indicative of the Lower Canadian, the age of the cherty dolomite above Mosherville sandstone (new) is established as lowermost Ordovician. Name Little Falls dolomite for these beds is in error, and name Skene dolomite (Wheeler, 1942, Amer. Jour. Sci., v. 240, no. 7, p. 518-524) is not applicable because it was defined as Upper Cambrian. Hence, name Gailor dolomite is proposed for these beds. Thickness varies from about 150 feet in Saratoga region. West of Petrified Sea Gardens, formation is capped by massive 6-foot gray chert bed which locally contains CRYPTOZOON. Underlies Tribes Hill limestone in western part of area and Amsterdam limestone in eastern part of area. Section at Rock City Falls shows 12 feet of Gailor dolomite below thin Lowville limestone. Mosherville sandstone also referred to as basal member of Gailor.
Type locality: Gailor Quarry at northern edge of city of Saratoga Springs, one-eighth mile west of U.S. Highway 9, Saratoga Co., NY.

Summary:

Pg. 85. Traced into Fort Johnson member (new) of Tribes Hill formation in Mohawk Valley. Debatable whether some of dolomite beneath the Fort Johnson in that area should be assigned to the Gailor.
