screweduptexan Posted November 5, 2008 Share Posted November 5, 2008 Husband found this at Grapevine Lake in Texas in the Woodbine Formation. This is the fossil I took with me to Fossilmania that I couldnt get a consensus on whether it is a fossil or not. Heard from the guys running the DPS booth that Lance is the Woodbine expert. Any ideas y'all? Very interesting. I can't come up with anything clever enough for my signature...yet. Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted November 5, 2008 Share Posted November 5, 2008 im going with a fossil, im sure its not but to me it looks like a crab, you can see a body and arms Link to comment Share on other sites More sharing options...
Mike Murphy Posted November 5, 2008 Share Posted November 5, 2008 It really doesn't look like a fossil to me. It looks more like an ironstone concretion with high iron content (iron oxide) filling of cracks (dessication cracks?) that developed in the original concretion. Ironstone concretions are common at certain levels in the Woodbine, and there are usually a lot of them scattered on the upper surface of eroding Woodbine-Grayson contact exposures. I guess that I missed you at Fossilmania. I hope that you enjoyed yourself there. It gave me the opportunity to see people that I don't see but once every year or two, and some that I had not seen in several years. I met a lot of peope that I had never met before as well.

screweduptexan Posted November 5, 2008 Author Share Posted November 5, 2008 Yep, I had a good time at Fossilmania. I really did enjoy the trip. One guy at the DPS booth said it looked like an iron concretion, but (this is if I remember correctly) the other guy said that upon closer inspection with a hand magnifier it appeared to possibly be a fossil. It is definitely strange and interesting and will go into my rock/fossil collection nonetheless. Interesting though. I can't come up with anything clever enough for my signature...yet.

mommabetts Posted November 5, 2008 Share Posted November 5, 2008 I too, think it is a ironstone concretion, I have several of them. Some of them when broke open will have a "red paint" in them that the Indians would use for paint to decorate themselves and other things with. I have always called them paint pots.

tracer Posted November 5, 2008 Share Posted November 5, 2008 it's a squished spider and there's a tiny crab claw in the lower right part of the picture. they both look quite aggressive. <signed> Rorshach Link to comment Share on other sites More sharing options...
Auspex Posted November 5, 2008 Share Posted November 5, 2008 The pattern is vaguely reminiscent of a septarian nodule; my guess is mineral formation.

Guest Nicholas Posted November 5, 2008 Share Posted November 5, 2008 Well.. to me I see a very nice mineral formation. Interesting enough that I would keep it as an example and to add to my interesting mineral collection. Link to comment Share on other sites More sharing options...

tracer Posted November 5, 2008 Share Posted November 5, 2008 screweduptexan - i'm sorry i'm confusing. actually, i was just kidding. the thing on the upper left actually appears to be a cap from a soda bottle with two drops of soda in it. in the right-hand picture, the upside-down(?) thing look really looks like lace amber. sincerely, your friend tracer Link to comment Share on other sites More sharing options...

tracer Posted November 5, 2008 Share Posted November 5, 2008 ok, i'll be serious for a minute. the rounded, tubular areas seem almost to have a touch of translucence and burnished look to them that's more reminiscent of chalcedony or calcite or something other than the run-of-the-mill iron concretions i've seen. it also looks a lot different than the way cracks infill inside of septaria that tracer jr. has cracked (and he's cracked a bunch of them). i'm not saying it's not infilling of dessication cracks or something, but if you don't care about it too much, you might try polishing off the stuff a bit and see what the material looks like. odd finds that can't be adequately explained bug me almost as much as not being able to understand Steven Hawking's explanation of the universe.

PaleoRon Posted November 6, 2008 Share Posted November 6, 2008 Interesting limonite concretion. Link to comment Share on other sites More sharing options...
screweduptexan Posted November 6, 2008 Author Share Posted November 6, 2008 Interesting to live with tracer...hmmm..... 'Bout the rock: I have several septarian concretions/nodules and none look quite like this. Parts of the rock definitely resemble a septarian nodule, but small parts do not. If indeed it is all a septarian nodule, this is one interesting one. I will definitely keep it for my mineral collection. I can't come up with anything clever enough for my signature...yet.

tracer Posted November 6, 2008 Share Posted November 6, 2008 s.u.t. - if i had to bet, i'd bet ron's right. limonite concretion. Link to comment Share on other sites More sharing options...
screweduptexan Posted November 6, 2008 Author Share Posted November 6, 2008 Yes, the more and more I think about it...even at 3 am (anyone else do that?) the more and more I think it is a concretion of some sort.

screweduptexan Posted November 6, 2008 Author Share Posted November 6, 2008 Oh My GOSH!

LanceH Posted November 6, 2008 Share Posted November 6, 2008 I've searched one of the parks along Lake Grapevine once. I found an impression of a leaf in mudstone (?). If you click the pic it'll show the animated GIF with the veins highlighted. The leaf is hard to tell from the pic but obvious in person. The Woodbine is supposed to be a good producer of plant fossils in certain zones. Link to comment Share on other sites More sharing options...
