Auspex Posted November 23, 2008 Share Posted November 23, 2008 More nice fossils; #s 2 and 5 are my favorites (for display). I think #6 remains in your "outdoor collection", yes?

You are right, it's too big abd heavy, I fixed it on my camera, cause here you can't find very often so big piece of rock with prints. Auspex, what do you think about this one?

Thanks tracer, I'm Russian speaking person and know what does it mean, just thought that may be there is some reason to use particulary Russian slogan, some Russian speaking friends, for instance. Thank you for comment. Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
Auspex Posted November 23, 2008 Share Posted November 23, 2008 Auspex, what do you think about this one? I can only offer my observations. The pattern does not appear to have symmetry, but it does seem to be present in successive layers, and it seems to have carbonized remains impressed into the pattern. I would love to know what it is!

You can see inside view (on the cracked side). First impression was it's a calamites prints, but then I changed my opinion. Would it be any see animal?

Would it be any see animal? I don't think animal ,perhaps vegetal ,or mineral ....,epidermal cuticule of calamites ? ,the black color seems to coal on the brown shale ,so coal is végetal ....

docdutronc Posted November 23, 2008 Share Posted November 23, 2008 Thank you, Bruno, have you any idea about these pics: the second picture is like wood ,I see wavy ribs ,perhaps syringodendron or remains of sigillaria ..... Link to comment Share on other sites More sharing options...

RomanK Posted November 23, 2008 Author Share Posted November 23, 2008 the second picture is like wood ,I see wavy ribs ,perhaps syringodendron or remains of sigillaria ..... So, the cell-structured part of the specimen is a structure of the wood which is partially decomposed as Auspex said?

mommabetts Posted November 23, 2008 Share Posted November 23, 2008 So, the cell-structured part of the specimen is a structure of the wood which is partially decomposed as Auspex said? That sure is what it looks like to me. Link to comment Share on other sites More sharing options...
RomanK Posted November 23, 2008 Author Share Posted November 23, 2008 That sure is what it looks like to me. Thanks 'mommabetts', it's very interesting thing, because I've never seen the wood structure 'inside', only prints or fossilized wood - kind of 'outside' view. The lycopods wood consists of more lignin (xylogen) then cellulose one, that's why the oxygenation of the plants (arborescent) material was so difficult and slow in Carboniferuos time and that's why the concentration of oxygen was so high (32-35%).

tracer Posted November 23, 2008 Share Posted November 23, 2008 RomanK - I too think the structure looks like internal decay. i have seen a lot of wood where partial structure was evident. Link to comment Share on other sites More sharing options...
RomanK Posted November 23, 2008 Author Share Posted November 23, 2008 RomanK -I too think the structure looks like internal decay. i have seen a lot of wood where partial structure was evident. Thanks tracer for your comment. I noted the similar structure - rectangular cells - in some burned (oxydied) specimens I found. Bruno said he noted sigillaria wood feature on my specimen, so it's difficult to expect that lignin consisted wood was decayed heavily. But you are right there are a lot of fossils with good 'inside' structure. Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
