kerrimarie805 Posted January 11, 2018 Share Posted January 11, 2018 This is obviously not a seed fern fossil, but the "fossil guy" at the flea market across the river in Jersey told me that it is a fern. My understanding was that it is petrified plant material, a petrified fern. I'm not confident in his identification as he, I now know, missed several identifiable pieces (crinoid columnals and a chunk of perfect rose quartz, for example) or simply wasn't as into looking as he said he was. So, I need another ID! Again, as usual, it was found under the bridge behind my house in Bucks County, PA along the creek not far from the Delaware river.

izak_ Posted January 11, 2018 Share Posted January 11, 2018 Looks to me like some weathered sedimentary rock. Link to comment Share on other sites More sharing options...
Wrangellian Posted January 11, 2018 Share Posted January 11, 2018 It does look layered... Is it carbonaceous (coal) as it appears to be? Link to comment Share on other sites More sharing options...

I don't think this is carbonaceous, tho I have found plenty of obsidian and jet in the same area. I have found nothing like this, while I have found lots of what I know to be carbonaceous, being the obsidian and jet. Is there a way to check this piece?

Fossildude19 Posted January 11, 2018 Share Posted January 11, 2018 I'm in the geologic camp on this one. Looks like worn layers.

There should not be any obsidian in Your neck of the woods unless brought there by man. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

The flea market guy is not a good source of information and the spiritual rock people are often just plain wrong -- pfft. Now, I have to go get pics taken of what I'm sure is obsidian so you can tell me it's something else... Link to comment Share on other sites More sharing options...

MeargleSchmeargl Posted January 11, 2018 Share Posted January 11, 2018 Vote for geological. Never simply trust dealers. Every single fossil you see is a miracle set in stone, and should be treated as such. Link to comment Share on other sites More sharing options...
