Terry Dactyll Posted August 8, 2009 Share Posted August 8, 2009 Bruno.... Very Nice specimen.... Ive only ever seen drawings of this.... Could the rippling or corrugations be longitudinal compaction or shrinking of the cast during fossilisation?... Secondly... have you come across any leaflets at the junction of calamites, that resembles Phylotheca?... I came across a couple of specimens that could be Phylotheca and was told they are probably not, as it wasnt growing this far north.... and it was suggested that it could be rotting down calamites stem, even though the leaflets were of identical length and in perfect preservation....

Hi Terry ,I think you are speaking about "phyllotheca" ,look the commentary of Docteur Crookall about this kind of articulate plants ....a small correction is not Calamites ondulatus ,but undulatus small slip with the French language ,yes effectivly the rippling and longitudinal compaction may have been caused during the fossilization, one of my friends has a Calamites undulatus in 3 d, which is typical face "undulatus", the other calamites suckowii . best regards bruno Link to comment Share on other sites More sharing options...
Terry Dactyll Posted August 8, 2009 Share Posted August 8, 2009 Bruno.... Thanks, I will take a photo and show you, to see what you think.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Terry Dactyll Posted August 10, 2009 Share Posted August 10, 2009 Bruno.... Heres a couple of photos of the better examples I found of what i thought were 'Phyllotheca', some were less complete that this but when you get your eye in for things, you begin to see more, which was the case in this instance, in particularily when I found out it wasnt meant to be growing there.... I think the small diameter one shows more similar characteristics to phyllothecca, as the other has a shorter leaf length, although this could just be a higher up example from the plant.... I'd value your opinion... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

Hi Steve I think simply Asterophyllites equisetiformis, these leaves are fossilized in the plan, look at the drawing of Zeiller in french we say "verticille" of leaves, in English , "crown of leaves", I do not know the exact word,These leaves can be very long are attached at the node, in the supine position....

Nicholas Posted August 10, 2009 Share Posted August 10, 2009 Gorgeous Calamites!!! :drool: I wish I could find ones that good Link to comment Share on other sites More sharing options...
docdutronc Posted August 10, 2009 Author Share Posted August 10, 2009 Here the diaphragm of a plant probably articulated genus Asterophyllites, its diameter is 2 centimeters, you can see the remains of leaves..... Link to comment Share on other sites More sharing options...
Terry Dactyll Posted August 10, 2009 Share Posted August 10, 2009 Bruno..... Thanks for clearing that up, looks like I have some 're labelling' to do lol.....the shale plates put the plant parts in better context than a nodular piece.... Cheers Steve...
