PaulK Posted April 6, 2019 Share Posted April 6, 2019 Hello everyone, I'm hoping someone can help out with identifying which fossils were found during our trip to Tully, NY a week ago. I'm also hoping someone can recommend a good book for fossil identification? The first fossil I'm pretty sure is a crinoid stem. I don't know if it's possible to identify what kind of crinoid just by looking at a stem from one. Fossil one, approximately 1 inch in length. Fossil two, approximately 1 3/4 inch wide. I have no idea what this is. Fossil three, approximately 2 inches long. I have no idea what this one is either. Fossil four, approximately 1 1/2 inch wide. I know it's shell but I would like to know which kind of shell. I apologize for the image quality. Fossil five, approximately 1/4 of an inch wide. I'm absolutely clueless as to what this could be. 1 Link to comment Share on other sites More sharing options...
ynot Posted April 6, 2019 Share Posted April 6, 2019 1 crinoid columnal. 2 cross section of bryozoan. 3 trace fossil - burrow cast. 4 is brachiopods. 5 another crinoid columnal. (end view.) Nice finds! 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF.

Rockwood Posted April 6, 2019 Share Posted April 6, 2019 1 crinoid stem section Ligaments hold the columnals together long enough for them to fossilize in articulation 2 tabulate coral The little ridges of protrusions along the columns being pores between the coralites. 3 trace Otherwise known as an ichno fossil. 4 see above ynot 5 see above ynot 1 Link to comment Share on other sites More sharing options...
Jeffrey P Posted April 6, 2019 Share Posted April 6, 2019 I also think that #2 is a cross section of a bryozoan. Tabulate corals are very rare in the Windom Shale. 5 Link to comment Share on other sites More sharing options...

Aren't the pores rather small for a coral? 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Fossildude19 Posted April 6, 2019 Share Posted April 6, 2019 #4 looks like a spiriferid brachiopod, probably Mucrospirifer mucronatus. 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Al Tahan Posted April 6, 2019 Share Posted April 6, 2019 Take a look at Carl Wilson’s “a field guide to Devonian paleontology in New York” robert linsley has a book on Devonian paleontology as well but Carl Wilson’s is more updated. You wont find very many good sources for Cronoid ID 3 Link to comment Share on other sites More sharing options...

The Tully site is the Moscow Formation Windom Shale (Middle Devonian). It is the same formation exposed at Penn Dixie and at Deep Springs Road. The fauna is very similar to the Deep Springs Road Quarry site (which is the easternmost exposure of the Windom Shale) and very different from Penn Dixie. 4 Link to comment Share on other sites More sharing options...

And thanks @Jeffrey P !! I think I know what location that is....big huge hill with talus all over? perhaps I’ll visit it someday Link to comment Share on other sites More sharing options...
Rockwood Posted April 6, 2019 Share Posted April 6, 2019 @PaulK In an end view, or cross section, are the shapes circular or polygonal (pentaganal) ? Link to comment Share on other sites More sharing options...

Yes, it is the same hill in the link that Fossildude19 provided. My wife and I went back again today and were the only people there. Link to comment Share on other sites More sharing options...

We went back to Tully again today and I found to pieces of what looks like coral to me. Both pieces of coral(?) seem to have the same texture around outer portion of fossil. The first fossil is approximately 3 inches in length. The second fossil is approximately 2 inches in length. Link to comment Share on other sites More sharing options...

Looking at this spirifer, it seems like you could place a drywall screw (not a nail) at the interface of the fossil and the matrix on the right side and tap it. Then the matrix should separate from the from the wing of the brachiopod. It will likely reveal a nice tip. Even looking at the crinoid in the first picture, further exposure might be possible with this easy technique. Happy hunting, Mike 1 Link to comment Share on other sites More sharing options...

I would have never thought of using a drywall screw to remove some of that stuff. Link to comment Share on other sites More sharing options...
minnbuckeye Posted April 6, 2019 Share Posted April 6, 2019 Someone once told me to NOT use a nail and told me why. But I can not remember the reasoning. Just head this advice. It makes a big difference when prepping fossils low budget!! Mike Link to comment Share on other sites More sharing options...
erose Posted April 7, 2019 Share Posted April 7, 2019 Scale is always important in photos. The confusion sometimes between corals and bryozoans is a good example. The zooids of bryozoa are never bigger than a fraction of a millimeter, while the individual corallites of a colonial coral will be a millimeter or bigger. The only exception I know is the enigmatic Tetradium from the Upper Ordovician and it is possibly neither a coral or a bryozoan. The specimens in the photos are most definitely bryozoans. 1 Link to comment Share on other sites More sharing options...
