Could use a second opinion. Mahantango formation of the Devonian from Pennsylvania 

 

1 a broken bivalve, brachiopod or crinoid?

2 shell material with a spiriferid brachiopod

3 brachiopod

4 crinoid?

5 crinoid and shell material?

6 fenestella bryozoan?

7 not sure maybe just the rock

8 fenestella bryozoan?

Hi,

 

How many times have you posted this subject ? This is at least the second time I’ve read this topic, so at least one other one has already received a response... It is useless to multiply the posts, only once is enough.

The photo of #4 shows the subject in a more informative view. It's still in tough shape though.

I believe there are two tabulate coral colonies here. One larger, and the smaller to the left of it. They have a radial arrangement.

Hi Coco,

 

I respectfully disagree that this is useless. All of my posts are from different rock chunks I found. I am new to this and have been using resources provided by the kind people on here to practice. I simply wanted to check my progress. What’s the harm in that Coco?

OK, I didn't seen there are not exactly the same pics, but you have put some pics here from the same area :

 

It is better to put all the photos of a site on the same subject, numbering them as you did.

I think some confusion resulted from having three different topics with very similar titles and specimens.  To get better feedback, you might consider fewer specimens per topic and distinguishing titles.  :fistbump:
