Lone Hunter Posted March 16, 2021 Share Posted March 16, 2021 Took my dogs out to Grapevine lake, frequently go there, kicked this up in a sandy area close to swimming beach. Quite puzzled, there are no such concretions in Woodbine here and pretty sure no fossil involved. I've only seen oysters, Turritella and dinosaur footprints. So this appears to be crystalized in the center, with spirals of different color granules and crystals wrapping around very fine grained structure in the shape of a bottle. It's got to be something, but what? Looking forward to an answer!My only decent Woodbine find. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted March 16, 2021 Share Posted March 16, 2021 Nice Turritella fossils. Sorry I can’t help with the mystery fossil. I remember seeing lots of impressions and molds of wood in the iron-rich sandstones especially on the north shore near the foot prints. Have you seen the wood? My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

Lone Hunter Posted March 16, 2021 Author Share Posted March 16, 2021 Yes and I've got some pieces somewhere, that and the black coal, or is that wood also? I love the colors of sandstone there. Link to comment Share on other sites More sharing options...

I love the colors of sandstone there. It could be coalified wood. Most wood from the Cretaceous in north Texas is coalified. I even found a few coalified pieces that also were partially pyritized.

Lone Hunter Posted March 16, 2021 Author Share Posted March 16, 2021 Thanks for clearing that up, thought coal was more of a mixture of things. First time I heard of coalified wood, so learned something which is why I come here! Link to comment Share on other sites More sharing options...

JimB88 Posted March 16, 2021 Share Posted March 16, 2021 Looks like a shrimp burrow to me. Or a hematite tube maybe. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 16, 2021 Author Share Posted March 16, 2021 As far as I know no crinoids or shrimp there, not familiar with a hematite tube but don't see any hematite in it. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 17, 2021 Author Share Posted March 17, 2021 Ooh I just ran across a picture of 'fossilized lightning', checked it out since I never heard of such a thing...could it be that's what this is? Link to comment Share on other sites More sharing options...
daves64 Posted March 17, 2021 Share Posted March 17, 2021 I don't think that is a fulgarite (fossilized lightning). It may very well be a burrow of some sort. Or a really ancient bottle prototype (dino's had to have SOME fun, right?) Accomplishing the impossible means only that the boss will add it to your regular duties.

Lone Hunter Posted March 17, 2021 Author Share Posted March 17, 2021 Or at least the cavemen did, then this was the first shot bottle haha. Wish my camera could get better close-ups, it actually looks like melted sand. I was only comparing it to all the pictures and descriptions and it seemef to fit, that and the spiral patterns of crystals is something I haven't seen on any rock or burrow. Since I did find it in sand it made sense in my mind. Oh well, I'll put in my miniature bottle collection! Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 17, 2021 Author Share Posted March 17, 2021 Funny, I have another burrow, I think, which I started thinking was also fossil lighting. Thought I'd throw it in for more expert opinion. Link to comment Share on other sites More sharing options...
ThePhysicist Posted March 17, 2021 Share Posted March 17, 2021 Not seeing any fulgurites here. They can vary quite a bit in form, but I'm not seeing any features that convince me. No vesicles, dendritic forms, not hollow, not seeing melted sand grains, etc. Your best chance at finding them is in the desert or on the beach.

Lone Hunter Posted March 17, 2021 Author Share Posted March 17, 2021 Well it was a swimming beach at Lake Grapevine, probably not the same as real beach. Nevertheless thank you for your time and knowledge. I'm happy with cool burrows! Link to comment Share on other sites More sharing options...

Mahnmut Posted March 17, 2021 Share Posted March 17, 2021 No offense, but vulgarities I have seen are composed of something else. fulgurites on the other hand... Does not look like a fulgurite to me.

Lone Hunter Posted March 17, 2021 Author Share Posted March 17, 2021 Can't find any examples of vulgarites, what's the difference between that and a fulgurite?
