I recently visited a few formations around PA,

The Montour preserve pit happened to be on the way and I stopped by, 

The location was quite picked over as @historianmichael told me, but we did manage to get some nice finds.

I will post a trip report later but for now, I want to get some IDs for some of my finds from here and another location.

 

 

First, is what I thought in the field was a brachiopod but upon closer inspection, I realized that this is probably my first pteriomorph mollusk which is very exciting for me, my question is: Which? I looked through Linsley and multiple look similar, I just don't have enough experience with these to really be able to tell.

3. Not sure if brachiopod or bivalve, leaning towards brachiopod. Once again, don't know which

5. Another Ambocoelia? 

Edit: Now seeing these pictures it is a lot harder to tell what it is than in real life, sorry about that will try to get others later.

Don't need an ID for this one, just wanted to post it here. This is the tiniest Greenops I have, we actually found a few of them on the trip. I also found my biggest Eldredgeops piece on the trip, it was a pygidium which was about two centimeters in width, sadly that one fell apart in my hands before I could get the superglue

Misha, 

 

# 1 looks like the brachiopod Protoleptostrophia perplana.

It is a strophomenid,  at least. 

 

Don't know if you have THIS, ... I just found it.

Huh, that little part sticking out threw me off.

Still a pretty cool find for me.

Thank you, Tim for the help and the new Resource.

I will be checking that out

Unfortunately, the preservation on these is less than optimal.

Some of them are internal molds, as well.  :( 

Try to take your pictures from directly above, and hinge line up.

Thank you for the advice, Tim

Mycurrent thinking about the two similar brachiopods is that they are Tropidoleptus.

The other one looks like an Orthhid but I can't say much more, I will try to get more photos but I can't say it will be helpful since it is mostly covered by rock.

The tiny bivalve would be hard to photograph in any other way as it is on the very edge of a piece of shale, but I will try

Just talking for future reference, Misha. ;) 

The small white one may be a Devonchonetes sp.

That's probably it, the shape, especially along the hinge seems more accurate.

Today I also found this strange object today, it has some organic shapes in it but I do not recognize any of them. Is this weird blob actually a fossil? or am I just seeing things in it? 

The whole thing is about 2 cm wideS20200825_0006.jpg.0b757ff088c3f859b6306b5fc5fd76c1.jpgS20200825_0009.jpg.08f90c59c741d205023dfd2d57e3cfc9.jpg

It has been quite a while since this post but I just wanted to add a quick update, 

The above fossil has been laying around in my collection for a year without me knowing what it was, but just recently after visiting the quarry at DSR and looking at the very similar fauna there and finding a fossil that was preserved in an almost identical way I have finally figured out this mystery.

I believe that the object above is the gastropod Paleozygopleura sp., while most of its shell is covered up you can see some of their very distinct ridges peeking out of the fossil here and  the form of the fossil is exactly the same as the other examples of this genus I have.

As for the stuff covering the shell and surrounding it in the matrix I am not yet sure, I think that it may be either bryozoan encrustation which I have seen on these fossils from DSR or just some strange artifact of the fossilization process.

It could be a bryozoan encrustation.

 

It could also be a "squish-out" .

The gastropod fills with mud, then the weight of the overburden sediments causes the shell to crush, and squish out the mud around it.

Also, your second item is indeed an Ambocoelia.

That is possible too,

Could I ask how you edited the photo? It looks so much better than the original

I use the free version of PhotoscapeX.

 

It is the best free photo editing software I have found.

Easy and intuitive to use.   ;)
