Deep Springs Road fossil IDs

[Misha]

Hello friends!

I've had some time to sort through, organize and take photos of fossils from my recent trip to DSR. I have also attempted to ID some of my finds using Lindsey's Devonian Paleontology of NY but have found doing so with the bivalves especially difficult, I'm not sure if that is up to me not having experience with then, them being generally harder to differentiate or a bit of both.

Starting off with the lophophorates:

1. This brachiopod is a Chonetid, I initially just thought that it was Devonchonetes which is common at the site but looking closer it looked much more like Longispina mucronata to me, would this be accurate?

2. Next, another Strophomenid brachiopod. Protoleptostrophia perplana? 

3.

Finally, I believed this one was a hyolith based on the shape and size but

@Fossildude19 believed this one may be a nautiloid. I'm still inclined to say hyolith but would like to hear other opinions.

I forgot to include a scale here but the shell is about 2 cm long and .5 wide

.

Pteriomorphs:

4. .I don't have much to say about these, they range in sizes but their form looks quite similar, I am not sure if they are the same species or different.

Shell 1

Shell 2

Shell 3

Shell 4 

Shell 5

6. This one also looks quite similar to the last few but the shell itself seems a bit more elongated.

7. this one although just a partial was the only one of the kind I found and still pretty well preserved which made me decide to keep it, not sure about the ID though. Pseudoaviculopecten?

8. I'm throwing these in here because I also had them photographed although I don't think these are bivalves, the objects have an iridescence to them and lack any shell detail beyond the wrinkly texture you see here, might these be phyllocarids?

 

Will add more photos soon.

Any help is really appreciated,

Thank you.

Okay, I have taken a few more photos and I think this will be the last batch for now but if I uncover any more unknowns I will be sure to add them here.

Bivalves:

9. The first few of these fossils I think may all belong to the genus Paleoneilo, but I am not sure if this is accurate and if it is, what species they may be.

For the third piece the large shell is

10. I found one similar to this online which is labeled as Tellinopsis subemarginata but once again I am not confident in my ability to ID these bivalves.

11. these two have similar growth lines and overall shape but I don't know what the ID may be

12. this piece is quite similar to some of the pieces posted previously but the shell seems more elongated, not sure what the ID may be.

13. This one is interesting, it's squished flat and contains much of the actual preserved shell on there, the shape is very different from the other bivalves I've seen from here and I don't know what it may be.

14. Once again, two very similar shells, I am not sure what their IDs are.

15. This shell is not completely out of the rock so it may be difficult to ID but the growth lines on it are distinct from any other I have.

16. On the same piece as the large strophomenid, this has beautifully splayed out valves, they are quite large and a bit more square than all others I've seen, but lacking in surface detail.

17. This piece contains two large bivalves, I think the largest is Cypricardella, but I am not so sure about the other one.

18. Very beautiful, elongated shell, not sure about an ID.

19. A very small shell with an interesting notch in it, I saw a few like this in Linsley but not sure which it may be.

20. Very small and elongated shell, I really like the shape of this one but not sure about an ID.

21. A small Modiomorpha?

22. These two are very similar are they Nucleoidea?

23. this is a really beautiful bivalve, slightly iridescent, not sure what it is.

 

and finally the last piece for now will be this:

24. There is no shell on it and the slight curvature to the piece makes me think if it may be a partial goniatite? Not sure.

 

Once again, all help is greatly appreciated,

Thank you.

@Jeffrey P 

 

Last one is a piece of Goniatite. 

 

Misha, 

It might be easier if you put numbers next to the photos, and descriptions on the top of the photos. 

[Misha]

Here's a few fossils I'll add here quickly,

25. I've found a lot of these small straight shelled cephalopods, @Fossildude19 I believe you sent me some from this area labeled as Dolorthoceras, would that ID fit for these too?

26. And this one I was very confused about at first, it displays branching structures which made me think maybe coral or some kind of other colonial organism, but those don't seem to be present at this location so now I am thinking that maybe part of a crinoid holdfast? I hope it shows up okay on camera.

Other smaller branches on the side of that same rock:

Any thoughts?

@Misha

 

I would say so.

 

 

# 10 is Tellinopsis subemarginata.

# 20 is  Goniaphora sp

# 21 is Modiomorpha.

[Misha]

Okay, I think I have gotten a few more IDs but I am not completely sure about all of them.

4. All of those pteriomorphs look like maybe Leiopteria sp.?

9. These seem like Paleoneilo sp. to me

15 Carydium?

18. I think may be Grammatodon sp?

19. Finally, I think this one may be Nuculites oblongatus?

This is all for now, I will update this if I come up with any others or change these ones.

Not sure if you have Wilson's guide, but if you don't it is worth having.

Thanks Tim! I don't have it and have been looking for a place to buy it. This will be very helpful

Hello everyone, 

I have another fossil that I would be interested in getting an ID for as I myself am not sure.

This is a brachiopod I found in some leftover shale from my trip. None of the shell material is present as this is an internal mold of the organism. It has a pedicle opening which is unlike other brachiopods I've seen from here, I assumed that it's an Athyrid, after looking in the field guide the closest match I could find is maybe Meristella? The shell is about 1.5 cm long

thank you for any help!

[Fossildude19]

@Misha

I agree - this looks like a Merristella barrisi.

I looked in the field guide and it says that one is only found in the Tully formation, are you sure this could be it?

I also spotted Charionella rostrata on the next page and the general shape and adult size seems to match closer to my specimen, maybe that is also a candidate?

One thing I've noticed is that the Formation information is not exact in the field guide.

I have found a few things listed as not from a certain formation, but they do exist there.

That said, it could very well be Charionella rostrata.

Another possibility is Cryptonella planirostris - page 119 in Wilson's guide.

@Fossildude19 believed this one may be a nautiloid. I'm still inclined to say hyolith but would like to hear other opinions.

With this picture, I have to agree it's a Hyolith. 
The triangular shape stands out better here.

 

# 26 is a rugose/horn coral. These are relatively rare at DSR. I've only found two in a number of years searching there.

Nowhere near as common as they are at Penn Dixie, or other western NY sites.

It certainly looks look a solitary rugose coral to me, too. I’m not sure it’s branching (unless you can see actual branching points). There may just be a few of them close together. 

[Misha]

@Fossildude19 @tombk

#26 was just a partial, I found a big part of the rest of that specimen a few days ago, I still believe It's a crinoid holdfast as this part has lots of branching, although I may be wrong.

Didn't know any corals we're found at DSR, that's interesting!

Aulocystis ?

That actually seems like a much closer match!

I was wondering why it was strangely getting wider towards the branching points.

Once again never considered that there may be any corals at this location, if this is it would be very interesting!
