What is this hybrid brachiopod?

[Peat Burns]

Under magnification does the surface have tear-drop-shaped granules with their axes oriented parallel with the costae? 

 

Does it have fine capillae visible especially on the fold and sulcus?

Here is a comparison with a mucrospirifer

Beat me to it. As I looked at the first few photos, I thought mucrospirifer, but it was awfully lg. 

 

Got me

I’ll take a look as soon as I can. I’m all packed up from my big move. 

 

I’ll do an update when I do

Found 3 nice ones on 7/23/2019 in Livingston County NY. Orthospirifer marcyi  is the species that fits the size. These are from 65-75mm.

Hey nice finds mike! Are they more common your way vs Buffalo? I only found 1 in buffalo ever

Yes and No. I only find them at one locality and I usually find one or two each time I collect there. Preservation can be rough on these big brachs and many are squished or distorted. Complete, inflated, with wing tips are rare.

hi, can you take a picture (close up) of the Encrusters (epizoans) on the brachiopods? 

Edited January 8, 2020 by Brach3

[Al Tahan]

@Brach3 sure!! I’ll post it in the next day. I know one is Hedrella filiformis. Stay tuned!

[Fossildude19]

The hitchhiker on the first picture is a dacryoconarid, like styliolina.

[Al Tahan]

@Brach3 here’s a few up close photos. I noticed there was no scale so I’ll throw that in first. 
 

I might have to break it up to a couple posts to keep the picture resolution up. 
 

A few of the Spinocyrtias posted above with a scale

 

Lots of detail!!

 

A few more pictures 

[Al Tahan]

I like this one....to the naked eye this Gives me an eye illusion effect trying to focus on the bryozoan. 
 

couldn’t upload this image in a large size so it may not zoom in as nice. I really like this one too. Came out great. 
 

Spinocyrtias are probably my favorite brachiopod. Just love em. Hope you like these!  @Brach3

AL, please post all your Spinocyrtias from this photo in big size for my devonian archive photos  

Can you post 1 brachiopod from different sides in one comment + extra macro photo? (photo Brachial valve and photo Pedicle valve of 1 brachiopod in 1 post, see for example link).

Because I need to see the coral growth point (start point), but I can't  it/s very interesting because coral has grown across the brachiopod commissure. 

 

The possible combinations (and the most interesting thing) for a host (brachiopod) and an epizoan are as follows: "Relationships to live hosts / Relationships to dead hosts". 

On my opinion "Relationships to dead hosts" because apertures of Hederella sp. grow in the direction of bottom sediments (red line). See for example some brachiopods from D3 where Hederella sp. grows in the direction of commissure to .

 

 

Feeding advantage. Some organisms may have benefited from feeding currents generated by the host (oxygen, food, shook off the mud etc). 

 

See for more it's so interesting 

 

From the other side it looks like "Relationships to live hosts", because (?)Aulopora sp. grows to the commissure (area of inflow / outflow). See similar finds (fossils) from D3 (sometimes Aulopora sp. repeats the commissure of Cyrtospirifer sp.    :))

Yes, fantastic!!! May be you can help me, I haven't seen Spinocyrtia sp. and there is incomprehensible moment on the brachiopoda. 

 

What is this? I don't understand. Is it Bryozoan or micro-sculpture of Spinocyrtia (Brachiopoda - "microfila, and very few tear-shaped granules")?

I've seen this in [PDF] GM Ehlers, JD Wright The type species of Spinocyrtia Fredericks and new species of this brachiopod genus from southwestern Ontario, 1955  and In TREATISE ON INVERTEBRATE PALEONTOLOGY, Volume 5, 2006 says about "granules", but there is no granules on the photo. What is this? 

It's very interesting Bryozoan. Do you have ane more fossils like this? There is some problematic for me in D3 may be answer will come from the past? (D2) 

What is the Genera of this Bryozoan?

 

!!! FIRE !!!   !!! 2 in 1 !!!

There is "Relationship Epizoans - Epizoans" 

It's VERY rare fossils in Russia (D3) ... faint... call 911!!! 

 

Question: Do you have fossils ("a relationship between two species in which at least one species is harmed") like this link?

Can you make photo ("image in a large size") of these  №1 и №2? 

 

№3 It looks like Microconchida may be Palaeoconchus sp. (Do you have Genera Microconchus sp. in your region?)

Class: Tentaculita Order: Microconchida (from the Upper Ordovician to the Jurassic).

For note: Spirorbis (Class: Polychaeta Order: Canalipalpata) was once thought to have a fossil record extending back into the Early Paleozoic, but now all pre-Cretaceous spirorbins are known to be microconchids.

 

 

What is this? I can't see too small but it look like something very interesting

 

"Hope you like these!"

  I like them VERY MUCH!!!

"Granules" refers to the tiny bumps all over the surface of Spinocyrtia granulosa. Think of find sand particles: in English, they are also called grains. "Granular" texture is "grain-like" (or "grainy") texture, similar to sandpaper.

@Brach3 wow!!! this is all blowing my mind right now lol. 
 

I am going out of town today for 10 days so I won’t be able to get you more photos till then.

 

Id love to contribute to your digital collection and learn more about these specimens!

 

I may start a fresh thread in member collections when I do called “Als brachiopods”. This way we can have a killer thread with all these brachiopods in it!

 

so stay tuned for when I get back.
