Help identifying Devonian fossils in limestone from Western NY


Recommended Posts

Rock-Guy-17

I grabbed all these samples over the years from the same rock quarry in western New York, which excavates the Middle Devonian Onondaga Formation. I believe most of these are corals, but I was hoping someone could help specify what type of coral so I can organize them a bit better. I resized the pictures with the provided links to lower the quality, hopefully they are not too big still. Appreciate the help.

 

 

1. Two different fossils in this cherty material, on left I believe this is Rugose Coral because visible septa, but on the right above the letter "L" in the coin I am not sure if it is even a coral

2&3. A tabulate corals, I always believed this to be Favosites, but also some images of coral Emmonsia that I had not heard of that look similar, but I can't find many other sources on it. Is there a way to tell based on the pattern what type of tabulate coral it is?

4. Brachiopod? Bivalve? Not sure what more I can figure beyond that. The matrix for this one is very chalky

I think this one is a brachiopod.

I agree with "Fossildude19" about that last picture.

The Onondaga has a very large coral fauna.  It would be necessary to see good thin sections (both longitudinal and cross sections) to offer much more than a vague guess about the genus unfortunately.

Thank you for taking the time to edit that image. I would never have guessed that that one was a bryozoa

I essentially have a shoebox full of tabulate coral just like the ones above from this quarry and have heard that proper ID is difficult. I find them super interesting, from first glance they all look the same but I have started to notice some differences in the patterns of the corallite, pores, and walls.
