Stigmaria Or Lepidodendron Deeper Layer?

Recommended Posts

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.

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.
