docdutronc Posted September 19, 2009 Share Posted September 19, 2009 (edited) In a previous post I spoke about sigillariostrobus scars ...I found another one sample ..... This sigillaria trunks ,sigillaria mamillaris ,external bark and counterpart,shows a crown of scars, these scars are the insertions of breeding strobus (sigillariostrobus) , positioned in the upper part of the tree...

RomanK Posted September 19, 2009 Share Posted September 19, 2009 Hi Bruno, very nice finds and impressive preservation. What kind of sigillaria and lepidodendron is it? Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...

Shamalama Posted September 19, 2009 Share Posted September 19, 2009 Bruno, I'm a little confused, you are are saying the rough patch on the trunks are where the fruiting bodies were attached?

docdutronc Posted September 20, 2009 Author Share Posted September 20, 2009 Hi Shamalana yes very precisely this part of the tree! the first plate is a drawing of Professor LAVEINE Jean Pierre, the second drawing is a personal reconstruction bruno Link to comment Share on other sites More sharing options...
Shamalama Posted September 20, 2009 Share Posted September 20, 2009 Interesting how they "squeeze" the normal bark scales out of the way. The part and counterpart is the best at illustrating that.

RomanK Posted September 22, 2009 Share Posted September 22, 2009 Bruno, you put the 'reproductive' scars just between the leaf scar columns on your reconstruction picture, but it's not so obvious from your specimens (pic. 3) from first post. Why did you consider so when made a reconsruction? Could you explain what are the small holes among the scars?

Why did you consider so when made a reconsruction? Could you explain what are the small holes among the scars? Hi Roman I imagined my reconstruction using as example Sigillaria tessellata whose "reproductive" scars are between columns of leaf scars, it is also the case for sigillaria with large ribs : S. laevigata, S.boblayi ,for the other species S. mamillaris, S. davreuxi, the scars are positioned very anarchic and deform the adjacent leaf scars... " Could you explain what are the small holes among the scars?" probably trace the veins traveling to strobus .... best regards bruno Edited October 4, 2009 by docdutronc Link to comment Share on other sites More sharing options...

Coco Posted October 4, 2009 Share Posted October 4, 2009 Bruno, I want to tell you that I don't reply very often after your posts, but I read with a lot of attention all your texts. You are a specialist, and even if I am not interested in wood, I like posts about that. Thanks for sharing, for you and others.
