Favosites parasiticus from Lockport, NY

The only other coral that I've found in the Irondequoit limestone Rochester Shale is a species of Favosites. Trying to discern different species of this very common coral can be difficult. However based on the corals shown on the NY Paleontolgy website, and the Primitive Worlds website I think it is safe to say that the corals pictured below are Favosites parasiticus.

One of the features I notice is the relatively large cells , or individual calices, and fairly random growth pattern.

Specimen 1

Specimen 2

Specimen 3 - The first picture of this specimen shows the underside of the coral and you can see that it colonized a piece of a Bryozoan.

All the specimens pictured above came from the Irondequoit limestone Rochester Shale near Lockport, NY. The Irondequoit limestone Rochester Shale is middle Silurian in age (Sheinwoodian stage) and lies within the Clinton Group.
