RomanK Posted September 8, 2009 Share Posted September 8, 2009 (edited) Last year I've found a specimen that looks like decorticated lepidodendron bark from front side and like stigmaria frome the back one. I thought that it's just overlapping of different part of the tree under the pressure. Today I made some drawing exercises and got an impression that back side is depper layer of the lepidodendron bark, look: Round scars on the back side looks like a stigmaria but lies according to diamond-shaped system. So, sometimes it's easy to confuse stigmaria and lepidodendron print you've got on found specimen.

RomanK Posted September 9, 2009 Author Share Posted September 9, 2009 (edited) Clever detective work; it is compelling evidence! Bearing in mind this conclusion I would assume that controversial bark discussed in my previuos post http://www.thefossilforum.com/index.php?showtopic=8578 can be identified as very decorticated lepidodendron or sigillaria bark that saved from leaf scars only 'feeding pipes' Obviously we have to take into account some distortions on the specimen surface.

RomanK Posted September 9, 2009 Author Share Posted September 9, 2009 On this picture you can see the both element on one side of decorticated lepidodendron bark (other specimen, compare with post No1) Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
