RomanK Posted November 17, 2013 Share Posted November 17, 2013 That is unusual. I know so called "ulodendroid" branch scar but I never seen so small in diameter Lepidodendron branch scars! Look at front, back sides and magnifying picture Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
Plantguy Posted November 17, 2013 Share Posted November 17, 2013 Hi Roman, that is an interesting find! I'm wondering if that is just another one of mother nature's plant anomolies or a recurring characteristic feature. I've seen some present day plants do some really strange branching for no some apparent reason. Looking forward to hearing/seeing what others have to say. Regards, Chris Link to comment Share on other sites More sharing options...

I don't think that's an anomaly. We just know quite a few about that. it's an additional evidence on fact that anisotomous dichotomy was a common thing for Lepidodendron as well. My first impresssion was - Lepidophloios, but then I saw the infrafoliar parichnos at the leaf cushion, so that's Lepidodendron mannebachense. Another find - Sigillaria adpression Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...

RomanK Posted November 17, 2013 Author Share Posted November 17, 2013 (edited) Hi Roman. Agreed, I wasn't clear. I was referring to the very small size of the branching. Regards, Chris Chris, you obviously remember the article "Contribution to knowledge on ontogenetic developmental stages of Lepidodendron mannebachense Presl, 1838" we discussed earlier. If you look at Fig.5 you can see absolutely the same (but a bit better one) specimen with the scars of pseudomonopoidal branches which beared the cones. I just think whether he (Oplustil) was right those shoots were branched.
