Awesome Ammonites

There are so many known fossil collecting sites in western New York that one rarely elects to “explore” new creeks or seek out new locations.  And the Middle Devonian Hamilton Group is so well known in quality, quantity, and diversity of species that there seems little reason to hunt elsewhere.  But on July 11, that is exactly what five members of the Rochester Academy of Science Fossil Group decided to do.  We stepped up section into the Upper Devonian and headed for a gully exposing the Cashaqua Formation near Middlesex, NY.  The rest of this article is not yet written, however the pictures have been inserted (7/13/2015)This rather large ammonite was found in float in the gully floor.  It is hosted by the grey Cashaqua shale.

Two ammonites found in the Parrish limestone bed midway in the Cashaqua limestone.  These fossils were found in place in the gully wall.

In places the Cashaqua shale erodes to form very pretty cascading waterfalls.
