DVL Posted February 10, 2019 Share Posted February 10, 2019 Any thoughts in this? Sandstone bolder found in Northern NJ (Newark Supergroup). About 7 inches long. Concave. I think one of the smaller ones was a cast but I'd have to go back and check. Thanks! Dwight Link to comment Share on other sites More sharing options...

LordTrilobite Posted February 10, 2019 Share Posted February 10, 2019 I agree that that does look like an impression of a bone. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

All except the last photo (they're all the same impression). The lower fragment in the last pic may have been a cast. I have to go back and take another look.

Rockwood Posted February 10, 2019 Share Posted February 10, 2019 Which direction is the light coming from ? I just can't visualize that as being concave. Link to comment Share on other sites More sharing options...

I know what you mean- I've seen the same effect when looking at photos of dinosaur tracks. Hard to tell if it's a mold or a cast. The light in the last photo is coming from the lower left. If I go back I'll shoot from a different angle. Link to comment Share on other sites More sharing options...
KimTexan Posted February 10, 2019 Share Posted February 10, 2019 Is it in an area where you aren’t permitted to collect? If you can collect it it looks worth carrying out. Pretty cool. I don’t think it’s identifiable though. I find artiodactyl bones, but there is no way to determine what genus or species without other diagnostic info. That said, this would have been from a specific geological period, Jurassic, per your title and surely there have been remains found in the formation that would match up to this. Maybe @WhodamanHD, @njfossilhunter, @RCW3D, @FossilsAnonymous, @Darktooth, @Gizmo May have some thoughts. I know they hunt the Chesapeake area, but may have some knowledge of this area or know someone who does. I know when I visited Calvert Marine Museum they had quite a bit of dino material there, but I’m pretty sure it was all Cretaceous. 1 Link to comment Share on other sites More sharing options...

Miocene_Mason Posted February 10, 2019 Share Posted February 10, 2019 Could have been a bone for sure, possibly archosaur. Hard to say with just an impression and I am no expert. It could alternatively be an invertebrate burrow, they are quite common in the Newark supergroup. Again, hard to discard this idea without seeing bone structure. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Carl Posted February 11, 2019 Share Posted February 11, 2019 I'm getting more of a plant vibe from this one. It looks quite flat. Very hard to tell from these photos and it's preservation. 1 Link to comment Share on other sites More sharing options...

The third photo down appears quite plant like to me, but it would seem to need to be flat. 1 Link to comment Share on other sites More sharing options...

I've been told the same by another paleontologist outside of this site-that they are plant stems or leaves. He said it may be possible to identify the species. Not bones but still pretty cool- Thanks again- I love this site! Dwight 2 Link to comment Share on other sites More sharing options...
Rockwood Posted February 11, 2019 Share Posted February 11, 2019 Just checked my plant room. I can see the base of a cycad frond compressing to look like this. 1 Link to comment Share on other sites More sharing options...
Zenmaster6 Posted February 11, 2019 Share Posted February 11, 2019 When I first saw it I thought broken baculite negative (impression) and then I saw the end which now makes me wonder if you have a bone of some kind. Best of luck, I hope the experts figure it out 1 Link to comment Share on other sites More sharing options...
