kauffy Posted February 21, 2008 Share Posted February 21, 2008 Heres one thats really puzzeling me...? is it wood, i have never found any wood from the triassic shales of nsw. The place where i found this i found different flora than i usually do...there was only this hunk and one smaller fragment near by....it is very heavy, very crystalized and does resemble, well to me, a piece of bark, wood fragment..... What do you guys think? Cheers! "Turn the fear of the unknown into the excitment of possibility!"We dont stop playing because we grow old, we grow old because we stop playing.

Guest N.AL.hunter Posted February 21, 2008 Share Posted February 21, 2008 It could be wood, but hard to tell. I usually find it good to look very closely, ie with a magnifying glass, at the end of the piece to see if any cellular structure is visible or any growth rings visible.

I would have to agree, I've seen lots of specimens which look similar to this. However there is a chance it could not be that so I think you should just take a closer look. Maybe try a museum or University to help out. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted February 21, 2008 Share Posted February 21, 2008 That second pic kind of looks like a sed. structure. However, I find some oxidized siderite logs that look similar in the Penn. coal fields. In any event, it is not "petrified", as that refers to replacement by silicification.

However there have been instances of wood preservation in other environments. While most of the wood fiber itself is destroyed, the bark tends to hold up better against decay. We find trace amounts of bark impressions in the siltstones here. Link to comment Share on other sites More sharing options...

Yeah, I have a piece of siderized log from a sandstone that a friend had to got up and tap on to "see" if it was not just a piece of wood. I also have a fairly large (20cmx30cm) piece of Lepidodendron that has undergone coalification and left a beautiful negative of the bark. If I ever get down to my warehouse, I'll grab them, and post some picks. Link to comment Share on other sites More sharing options...
kauffy Posted February 22, 2008 Author Share Posted February 22, 2008 thanks for all the information everyone, it does have a few layers on the edge (rings) Im going to go with wood, because I have never seen any other iron oxide rocks like this and it was in a new layer of silty mudstone shale, I will send a pic to a freind at the museum and see what he has to say.
