geodan03 Posted February 11, 2009 Share Posted February 11, 2009 I commonly find these at roadcuts. It is from either dolostone or limestone. It could be some kind of calcit crystal growth within the limestone itself. Pseudofossils and other oddities fascinate me, so i usually end up taking them home. These 2 pics arent that good, soon i will be buying a better camera that would allow me to take close up photographs. Thanks for your patience.

Guest bmorefossil Posted February 11, 2009 Share Posted February 11, 2009 i would call them blurry picturs haha, not sure but they look like some kind of crystal Link to comment Share on other sites More sharing options...
JohnJ Posted February 11, 2009 Share Posted February 11, 2009 Fairly sure you've found calcite. It will form in the fault fractures of the "limestone". There are a variety of local names, but it's still mostly calcite. If you drop one into a bowl of vinegar, it should start fizzing rather quickly.

Guest N.AL.hunter Posted February 11, 2009 Share Posted February 11, 2009 Agree on Calcite. Just to make sure, scratch it some and pour on some vinegar. It should fizz really well if calcite. Link to comment Share on other sites More sharing options...
Guest Nicholas Posted February 12, 2009 Share Posted February 12, 2009 Hrmm I seem to recall I have something very similar... Does it resemble this piece by any chance? I believe it is either mineral or fossil wood. Link to comment Share on other sites More sharing options...
JohnJ Posted February 12, 2009 Share Posted February 12, 2009 ...I believe it is either mineral or fossil wood. Limestone is formed in what paleo environment?? (SMACK!) Back to the books, Nick.

Bee's Mom Posted February 12, 2009 Share Posted February 12, 2009 Bee just got a peice that is very similar from the lapidary society and it was labeled petrified wood. I'm not sure of the location it was found. It has layers that can be seen if it is looked at on the ends. But I'm no expert! Hi! I'm a new member and I joined because my daughter loves goeolgy! She is 13 and has been bringing home rocks since before she could walk. She is in 4-H and she does the geology project too. For this summer's fair she is doing a project on copper minerals.

Guest solius symbiosus Posted February 12, 2009 Share Posted February 12, 2009 Limestone is formed in what paleo environment?? (SMACK!) Back to the books, Nick. While maybe not common, I've seen some clastic carbonates. x-bedding in near shore clastics. Link to comment Share on other sites More sharing options...
geodan03 Posted February 12, 2009 Author Share Posted February 12, 2009 Thanks for all your input. The resemblance to petrified wood is only slight. It is a kind of calcite growth within the limestone. I did use vinager and it efforvesced (spell??) / bubbled alot, so thats solved. I find alot of these things all over the place. When i find these i also seem to find very few fossils tho, might be a good reason for that. I got this fella along with some nice dolomite filled geodes near Belleville, IL.

lawooten Posted February 13, 2009 Share Posted February 13, 2009 Looks like fossilized wood to me from what I can see of the pic. The best days are spent collecting fossils Link to comment Share on other sites More sharing options...
lawooten Posted February 13, 2009 Share Posted February 13, 2009 i would call them blurry picturs haha, not sure but they look like some kind of crystal Ernie and I collected over 2000 pounds of fossil wood at Belgrade. Took three trips using different methods to get it in the truck. Now in the front yard our six foot dragon has fossil wood. Planing to get a life size wizard to go with it too.
