Herb Posted December 19, 2012 Share Posted December 19, 2012 Hi Rockwood Why am I so sure !!!, because the Professor Zeiller wrote, sometimes these crowns strobus are organized in several generations, I showed my findings to the lille city museum and I could compare with specimens figured in the original literature..... Best regards Bruno Hi Bruno, Amazing! You guys don't mess around when it comes to plant fossils.

Best regards Bruno In my opinion as it pertains to the originaly posted thread the question hasn't been answered. Why can't it be just a scar. The science not the faith that someone knows.

docdutronc Posted December 19, 2012 Share Posted December 19, 2012 quote : "The science not the faith That someone knows." Hi my friends I 'm "Cartesian" When observing repeats itself several times, the conclusion becomes a truth. Sometimes sientists emit erroneous theory and truth ensuing become obsolete. To date no one has proved otherwise on the crown of scars . 32 years on field to observe the fossil plants that confirms my theory . I have not found other conclusions. Your analysis is not objective but seems more subjective, unless he is stained with theological concept ??? in this case I would not debate !!!

Rockwood Posted December 19, 2012 Share Posted December 19, 2012 I've made no attempt at analysis, and I don't intend to call you wrong. I only posed a sincere question. It's your answer that seems theological to me. A statement such as 'scars tend to have a more bubbly or tumorish look', or 'the tissue does not heal it dies and leaves a rough opening' would be something that I would recognize as science.

docdutronc Posted December 19, 2012 Share Posted December 19, 2012 (edited) My dear Rockwood About pathology ....here is an example ...... Excuse me, I did not provide the answer you were expecting, I must tell you that the concept of branch does not exist on sigillaria genus , these plants are monopodial and rarely divided, some specimens possess division (dichotomy) only species in the upper Carboniferous. Then no concept of broken branch, my reasoning was circular and my eagerness to meet you in this way is the conclusion ... Here is a curious deformation axis Calamites sent by friend Maciek from Poland , And Maciek said : "it is probably a disease or an accident during growth with healing and regrowth, Calamite branch ends wih misshapen form ( I don't know similar to this one from the fossil record ) after this grows a modified continuation of the branch. Also interesting is changing number of vascular bundles on every node, and the number is doubled." http://i30.servimg.c.../15/73/1d10.jpg http://i30.servimg.c...0/15/73/110.jpg Best regards Bruno Edited December 19, 2012 by docdutronc Link to comment Share on other sites More sharing options...
Rockwood Posted December 20, 2012 Share Posted December 20, 2012 Bruno and all It would appear we have some lack of evidence. It's an honor to be taken seriously by someone held in such high regard. Dale Link to comment Share on other sites More sharing options...
tracefossilnut Posted December 23, 2012 Share Posted December 23, 2012 You can see the small scratch marks across this band. This is a trace fossil. A living animal was clawing at or gnawing on the bark. What you have is a fossil on a fossil. Since I collect only marine trace fossils, I am not familiar terrestrial trace fossil terminoligy, so I can't tell you the name for it. Link to comment Share on other sites More sharing options...
Auspex Posted December 23, 2012 Share Posted December 23, 2012 You can see the small scratch marks across this band. This is a trace fossil. A living animal was clawing at or gnawing on the bark... Are you referring to this fossil? I'm afraid that I cannot see the clawing/chewing marks you cite.

araucaria1959 Posted December 24, 2012 Share Posted December 24, 2012 As far as I know, macroherbivory of the kind that would be needed to produce a scar of that size wasn't established in the upper carboniferous yet. araucaria1959 Link to comment Share on other sites More sharing options...
