New York Mid Devonian Hamilton Group IDs

[Rock-Guy-17]

Good evening folks. I am working on curating my middle Devonian collection using the field guide book by K.A. Wilson. It is very helpful and has saved me tons of time, highly recommend. I am posting below a few of the fossils that I could not quite figure out using the book and was hoping for help. A few of these may be unsolved repeats from past posts. I realize this may be a lot so very much appreciated in advance.

 

1. Locality Livingston County

 

Two pieces of the same broken fossil

 

 

2. Deep Springs

 

3. Deep Springs

 

4. Deep Springs

 

5. Deep Springs

 

6. Erie Co.

 

7. Penn Dixie

 

8. Erie Co. 

 

9. Penn Dixie

3. Goniatite?

6. Maybe gastropods? A better quality photo may be helpful

7. Orbiculoidea

That is what I was thinking for 3, I thought 6 could be ostracods since they are so small but I have seen gastropods that size too. The big mystery to me is the first one.

#1  - Zoophycos

 

#5 - "Squish out" of a bivalve, possibly Grammysiodea sp.

 

#6 - Inarticulate brachiopods & microconchids?   Look at Craniops sp. perhaps?

 

#8  - Looks to me like a platycerid gastropod, along with Spyroceras cephalopod imprint.

#4 looks a lot like a partial Echinocaris punctata valve to me. Nice stuff!

I was thinking 2 could also be a Phyllocarid, but it appears too flat maybe. Tough to tell!

3 to 4 might be goniatites. Does tornoceras occur at this location?

Yes, Tornoceras does occur there. I agree, # 3 is a goniatite, and likely Tornoceras, but # 4 could also be a larger squish-out shell.

It seems like 4 is too ambiguous to tell. Now that I looked in the book it does seem similar to Echinocaris punctata due to the irregular shape.

 

I have a few Tornoceras from Spring Creek in Alden, I did not realize they can get this big

could I get a close up of those litle horseshoe shaped imprints?
