Recent Acquisitions, Lots Of Brachiopods- I Can't Id Any Of Them

[Pachyrhinosaurus]

I was wondering if anyone could ID these fossils. I bought them yesterday at a flea market.

First one is not a fossil. I don't have any extra information on it at all.

 

These brachiopods were suppodedly collected in PA. I'm not very knowledgable on brachiopods so I was wondering if anyone could confirm this. I was also told they were the insides or as he said it- 'guts'.

 

I was told that this is a piece of plant. No info on location but it does have impressions of a gastropod and bivalve in the matrix.

 

Can't say much about this one other than it looks like a trilobite.

 

More brachiopods, from Deer Lake PA.

 

This coral might be from Florida.

 

 

All of these were bought from the same dealer who sells mostly locally-found (South Central PA) rocks and all accompanied notes are from him also. Sorry about the poor picture quality. Bad lighting and shaky hands don't mix very well at all.

EDIT: Thanks to the moderator who deleted my accidental duplicate of this thread.

Your 'coral' looks more like a stromatolite to me, which is sediment mounds built up gradually by colonial bacteria, cyanobacteria or some such. Still a fossil, but more like a trace fossil in a sense. I think they are just as interesting because they are perhaps the oldest form of fossil on Earth. No idea how old this one would be - it could be anything. If it is from Florida it's probably not much older than Eocene from what I understand but maybe someone else will recognize more about it and let us know.

BTW I would concur with Brachiopods for 2 and 5, snail/bivalve for 3 (can't see how 'plant' fits with that one), trilobite tail for 4, and #1 looks like a polished sphere made from some sort of igneous rock. Someone else will have to give you more specific info.

[Pachyrhinosaurus]

Thank you. Now that you call it a stromatalite I think there is one at a local museum which looks very similar. I'll check that out when I go next.

My guesses could be:
1 - just a polished rock (not a fossil)
2 - brachiopods
3 - gastropod with bivalve imprint
4 - trilobite imprint in matrix
5 - brachiopods
6 - oysters

[Auspex]

...6 - oysters

This is my first thought too. A picture of the other side might clinch it.

Here are some better pictures of the last one including the bottom.

Nope, not an encrusted oyster; the resemblance was superficial.

[Guguita2104]

The last seems stromatolite, to me.

Regards and welcome to the Forum,

I see some similitudes with this specimen. In your opinion what could be this? :

[Guguita2104]

In my opinion a cyanobacteries fossil colony (stromatolite), also.

[abyssunder]

I intentionally cropped the picture I've posted to see what's your opinion about that specimen. It is one of the picture of the month gallery of the Friedrich - Alexander University Erlangen - Nurnberg, labeled as stromatoporoid. http://www.gzn.uni-erlangen.de/en/palaeontology/events/fluegel-course/
Is not possible that specimen #7 to be oyster(s) encrusted by stromatoporoid(s)?

Really strange ...Let's the experts say their opinion.

P.S:Abyssunder can you explain me how can an oyster be encrusted by stromatoporoids?
