...Christopher B. Waid; D. Jeffrey Over Abstract Conodonts from the Densmore Creek Phosphate Bed at the base of the Maplewood Shale in Irondequoit, New York, include Panderodus unicostatus , Pranognathus tenuis , and Icriodella discreta . The taxa Ozarkodina cf. Oz. hassi , Pranognathus tenuis...

... and the Irondequoit Limestone. The profound lithological and faunal differences between the Lower Clinton strata of western New York and those of the Niagara Peninsula in Ontario are probably the result of deposition in a shallow basin under conditions controlled by proximity to the Cataract shelf (Bolton, 1957...

... Formations. The Clinton Group is subdivided into 16 formations. In the west, the Clinton Group includes the Thorold, Reynales, Irondequoit, and Rochester Formations. In central and eastern New York, this group is subdivided into the Oneida, Bear Creek, Kodak, Sodus, Wolcott, Otsquaqo, Willowvale, Sauquoit...

... is probably Manlius or older. The Salina Group in Pennsylvania is readily correlated northwestward; good regional markers are the Camillus Shale of New York and the C shale of Michigan. The top of the Salina G corresponds nearly to the top of the Tonoloway, the top of E to the top of the Wills Creek...

.... In the epoch between the two water stages the water plane was gradually b u t not continuously lowered by the discharge of water eastward across western New York. This discharge followed successively several different lines, which were roughly parallel with one another, but cut the lines of modern drainage...

...Kam K. Chiang ABSTRACT This paper presents a new correlation of the Niagaran Series of southern Ontario (represented by the Neahga, Reynales, Irondequoit, Rochester, DeCew, Lockport and Guelph formations in the Allegheny Basin; and the Fossil Hill, Amabel and Guelph formations in the Michigan Basin...

... to east, the Niagara Escarpment extends for more than 1200 km though Wisconsin, Michigan, Ontario and New York State. The strata of the Niagara Escarpment comprise carbonate and siliclastic formations of Ordovician–Silurian age that dip gently SW in the range of 3.5–12 m km −1 in the Hamilton area...

... and New York belong to the upper part of the Clinton Group. The condensed Lower Silurian succession of the Ontario part of the Niagara Peninsula ( Fig. 2 ) has made it difficult to correlate the Llandovery strata with their generally coeval formations in New York State. Since the initial proposal...

... Pond stratigraphy all are compatible with an ice advance and retreat culminating between ca. 13,300 and 13,000 cal yr B.P. or slightly younger. Irondequoit Bay near Rochester, New York, is the location of a buried bedrock gorge created by inferred multiple occupations of an ancestral...

Dip is toward the south about 30 feet per mile in Ontario, steepening to 50 feet per mile...

Thus the scope of the project was extended eastward to Clinton, New York, the full length and breadth of southern Ontario, and westward into northern...

The Niagara Escarpment is a landform composed of sedimentary rocks that extends through southern Ontario and into New York, Michigan and Wisconsin (Armstrong & Dodge, 2007 ; Figs  1 , 2 ). The structure exposes sandstone, shale...
