Shale_stack Posted January 25, 2023 Share Posted January 25, 2023 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?

Coco Posted January 26, 2023 Share Posted January 26, 2023 (edited) 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.

Rockwood Posted January 26, 2023 Share Posted January 26, 2023 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. Link to comment Share on other sites More sharing options...

Coco 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?

Coco Posted January 26, 2023 Share Posted January 26, 2023 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.

What’s the harm in that Coco? 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. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
