Summary:

Pg. r148. Cornwall limestones. A series of thin beds of limestone overlies Longwood shales at several points in Orange County, southeastern New York. Beds carry fossils which correlate them with Lower Helderberg and Waterlime farther west. The term "Cornwall limestones" is not here proposed as a formation name, but is used merely as a convenient designation for the series till further field work shall have decided the extent to which subdivision can be carried. Age is Silurian and Devonian.
[GNC remark (ca. 1938, US geologic names lexicon, USGS Bull. 896, p. 524): Range in age from Decker limestone to New Scotland limestone, according to Hartnagel (Hdbk. no. 19, 1912). Name apparently taken from some one of the places in Orange Co., southeastern NY, that bear the name Cornwall.]
