Fossildude19 Posted April 4, 2019 Share Posted April 4, 2019 Hello, Can you take a picture of the item from directly above it? Top and Bottom would be useful. Also, Size? Everyone's hands are different sizes.

Fishinfossil Posted April 4, 2019 Author Share Posted April 4, 2019 Here's a photo of the bottom of it. Pics 1 and 3 are basically photos of the top of the piece. I'll see if I can get another image. Also, it is about 3-1/2 inches in length, 2 inches in width, and half inch in depth Here's Link to comment Share on other sites More sharing options...
Rockwood Posted April 4, 2019 Share Posted April 4, 2019 I think this an import from up north. They look like brachiopods, poorly preserved molds mostly, in Paleozoic rock left by glaciers. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 4, 2019 Share Posted April 4, 2019 Looks like erosion marks on a thinly bedded sandstone to me. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

digit Posted April 4, 2019 Share Posted April 4, 2019 Not looking that highly silicified to these amateur eyes. Possibly @ynot will chime in with a geological opinion. I am in the camp of thinking this is basically non-biological (other than possibly the traces showing in the top level of this laminated rock). Though I don't think it is a fossil, I do think it would make a stellar display mount for some actual fossils found in the same creek. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
caldigger Posted April 4, 2019 Share Posted April 4, 2019 One more vote for geologic piece. But it's definately cool enough to display on a what-not shelf. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted April 4, 2019 Share Posted April 4, 2019 The rock looks like chert or possibly a very fine-grained metamorphic quartzite. Notice the circular percussion scars on the bedding plane that are common in pieces of chert. Banding is also common in chert. 1 My goal is to leave no stone or fossil unturned.

ynot Posted April 4, 2019 Share Posted April 4, 2019 I agree with it being banded chert (with differential weathering). Neat rock, but not a fossil. Darwin said: " Man sprang from monkeys."

Jeffrey P Posted April 4, 2019 Share Posted April 4, 2019 New Jersey's Cretaceous streams produce a lot of interesting, oddly-shaped and colored stones. Much of it is glacial debris from up north. Other stuff is provocatively shaped concretionary material. Experience teaches what is a fossil and what isn't. Link to comment Share on other sites More sharing options...
Fishinfossil Posted April 4, 2019 Author Share Posted April 4, 2019 Thanks for the replies, sounds like it could be banded chert. I've had many fossil-looking concretions, but this one stumped me. Dang if it doesn't look and feel like bone! DPS AMMONITE - what did you mean by "percussion scars" and how are they created? I noticed those markings as well thinking they could have been bite marks originally. Link to comment Share on other sites More sharing options...

I noticed those markings as well thinking they could have been bite marks originally. Percussion scars form when a rock hits another object and forms a fracture. Chert and many quartz type rocks have curving or conchoidal fracturing. See the Wikipedia article: https://en.m.wikipedia.org/wiki/Conchoidal_fracture My goal is to leave no stone or fossil unturned.

Rockwood Posted April 5, 2019 Share Posted April 5, 2019 Brachiopod. Sorry I'm late. Wind took out my internet wires. Link to comment Share on other sites More sharing options...

Rockwood Posted April 5, 2019 Share Posted April 5, 2019 1 hour ago, Fishinfossil said: Rockwood, what am I looking at that you circled? I'm looking at something like this. From this perspective the rock looks like metamorphosed sandstone to me. There also seem to be shapes consistent with internal molds of similar brachiopods in the other side, and to a lesser degree (exposure) in the intermediate layers.

Mark Kmiecik Posted April 5, 2019 Share Posted April 5, 2019 Not something that would find its way into my collection. Over the years I've literally gotten rid of tons of "interesting" stuff because the crates filled an entire garage from top to bottom, front to back and side to side. I would be trying to separate those layers to see if there's anything collectible between them, although experience has taught me that it is a low-percentage possibility. If you don't have another like it or better, put it in your collection. If you already do, split the layers and see what you can find. My gut tells me there isn't much there. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
