Western NY Devonian Brachiopod Shell ID Help

[Rock-Guy-17]

Have some Mid Devonian brachiopod or bivalve shells that I am not sure about, tried to do some research on my own on what I found. Hoping to get some ID confirmation or help here. Greatly appreciate the help. 7 pictures below:

 

1. Bivalve Shell? Moscow Formation I believe

 

 

 

2. Brachiopod Shell, never found another like this one? Windom Shale from Livingston Co.

 

 

Wondering the difference between these two spirifers:

3.

4.

 

5. Rhipidomella? 

 

6. or is this Rhipidomella? 

 

7. Bonus, cephalopod? gastropod?

3 - Mucrospirifer mucronatus

4 -  Spinocyrtia granulosa

5 - Pseudoatrypa devoniana.

6 - Rhipodomella penelope

7 - Gastropod - Platyceras bucculentum

 

Please take picture of the first two from directly above, laying flat on surface, with the hinge  at the top of the picture.

Thank you for identifying those. More angles of first two: 

 

1.

 

 

2.

1 - looks like a bivalve, but it could be any number of them.  They can look fairly similar. Maybe something like Leiopteria conradi. 

2 - looks more like a gastropod to me, possible Ruedemannia trilix.

However, Mourlonia sp. is another possibility.

I can sort of see the shape of a gastropod for number 2 now, bigger than I thought it would be. Thank you for pointing me in the right direction.

Could 1 be a distorted Athyris spiriferoides? And 2 looks more like a Rugose coral than anything to me, would that be possible?

That is indeed a possibility. Hard to say, with the photos as they stand. Usually, I see more black shell like material on Athyris, but it could be.

The more oblong shape has me feeling like it's a bivalve, but it could be very distorted.   

If we could see the inside/back of number 2, it would be helpful. Could be a rugose coral, as well.

Are you sure about gastropod? Seem like the side picture are weird about top.

No I'm not. I mentioned later that it could be a rugose coral.

Having edited the picture of #1, I think it could actually be Meristella sp.

Just noticed I have to change the genus name of my Atrypa devoniana from Iowa.

Here are more pictures of 2. I wetted the specimen to expose some more detail

 

 

Now I can see a horn coral shape too

[Fossildude19]

I would go with Rugose coral for the last one now.

Nice catch, @Misha

Awesome, thanks for the assistance with this ID everyone!
