Summary:

The Ellicott Creek Breccia of the Bertie Group is here named as one of several waterlimes in the Bertie Group in New York and Ontario. It consists of varicolored, banded waterlime, rich in eurypterid and cephalopod remains. It has a massive middle unit which is probably the result of "reefy" algal masses, and variability in thickness of the unit is probably due to variation in algal mound development. Overlies the Victor Dolostone or Phelps Waterlime; underlies the Scajaquada Formation, all of the Bertie Group. Thickness at type section is 2.3 to 2.5 m. Age is Late Silurian.

Summary:

Bertie Group redefined in this report. Author includes the Akron-Cobleskill interval and the newly named Moran Corner Waterlime at the top of his revised Bertie Group. Bertie in western NY subdivided into (ascending) Fort Hill Waterlime, Oatka Formation, Fiddlers Green Formation, Scajaquada Formation, Williamsville Formation, Cobleskill Formation, and Moran Corner Waterlime. Ellicott Creek Breccia assigned to Fiddlers Green Formation as uppermost member. Ellicott Creek is stratigraphically higher and younger than the Phelps Waterlime Member and includes a black shale marker bed at its base on the Niagara Peninsula and at Williamsville, NY.
