Fossil tree?

[Moth.11]

 

I found this specimen in a pile of stones near the garden. Is it fossilized wood, and if so, can it be identified as deciduous or coniferous?  Thank you.

This doesn't look like wood to me. I think it might be an example of soft sediment deformation structures. wiki

I'm more of a tree and wood guy than fossil;  I'd say "No." to tree, or wood.   But I would say "Yes." to "there's something interesting going on here."  it actually looks, at least superficially, like some of my puzzling Lower Ordovician stuff; I see that 'this has to be the socket side of somebodies "ball and socket" joint!' more and more often.  In my case it doesn't help that there isn't much alive 475 Mya that could possibly have a joint like that.  :-)  I do lean towards "there's something biological involved" rather than "strictly geology."

I'm not seeing wood or bone here.  Looks geological to me.

Interesting find!

I'm thinking geologic as well--as the others mostly have already said. 

 

I am wondering what the geology around your area is like? Do you have lots of quartz rock/any metamorphic rocks nearby or is/was this yard find different and brought in by someone from somewhere else?

 

I've almost convinced myself after seeing this end view that this looks like a large piece of a quartz vein/layer with some deformation and the additional alternate banding/layering? is possibly foliation within maybe a schist or some other laminated rock? I wish that 5th photo was not so blurry as maybe it would help with that question. 

 

 

Is there any soil on the specimen? I cant tell but it looks like it may have some in the curve/folds--where I've drawn the 2 arrows on the above photo.

Are the little white specs just my imagination or simply distortions/highlites because I zoomed in (which can add details that arent really there)?

Or are they reflections of light/shiney from very small crystal faces that might support a metamorphic or another sedimentary rock idea along with the vein of quartz?

Dale (rockwood) is right, there are signs of soft-sediment deformation there

In my country, quartz is common

Thanks for ID. Very interesting specimen

Ok, I put up photos of my "similar" stuff, on my blog; link is here.   I will have to confess to a bias- as a biologist -  maybe I tend to see "life".  :-)    However - I am also deeply familiar with the incredible diversity of life forms - and how we're unfamiliar with it.

Do you have a geologic map of your area? It would show what kinds of rocks and their ages that are in your area. I know Poland has some fairly diverse geology as do many places!

Sorry, I haven' t got any map

Here you go....

 

There probably is a complete map somewhere that you can locate, but here are

4 smaller split up (I hope still zoomable) maps showing each corner of the entire country. NE, NW, SE, SW.

Find the color and/or its corresponding number on the map and then compare/match it against the legend on the right 

to find out what age the rocks are and what the types are.

 

Here's an example of what I mean below in case you havent seen this kind of map before:

 

The legend has unfortunately been split up and is shown on the NE and SE maps but it applies to all 4 corners/smaller maps. 

 

The first image below also shows cross sections of the rocks across the country. Pretty cool! 

 

NW

NE

 

SE

SW

Wow, thanks!!!

wow... Poland is a lot more of a geological mess than I had suspected.
