MOROPUS Posted June 8, 2009 Share Posted June 8, 2009 As I am not an expert on botanical stuff (although I love the aspect they get when they fossilize!), I bought again a nice piece from Northwest Spain. This can be one of the last ones you can manage to adquiere, since they come from old coal mines that are inside a protected area now (this happened two years ago; this plant material was very common some time ago; now is quite rare to see them in the market, and becoming desired pieces!) Well; who can Id it for me? I can`t find any clue for it... Link to comment Share on other sites More sharing options...
Terry Dactyll Posted June 8, 2009 Share Posted June 8, 2009 MOROPUS......... My best guess is Neuropteris flexuosa.... But Im certainly open to suggestions.... the central vein on the leafs seem very 'strong' for neuropteris, and the veination isnt quite so 'delicate'..... It could be the type of preservation, like 3d.... ive never seen this stuff before.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

Hi Maropus and Steve, I do not agree to Neuropteris flexuosa, it lacks the terminal pinnules common to all neuropterid ferns , I think Pecopteris polymorpha (polymorphopteris) the pinnules are fleshy, narrowed at the base, the central vein is marked (very "strong "as you say Steve .....all pinnules are pasted on all of their bases, neuropteris are tied to a single point...look the pictures These plants come from Spain, probably the upper Carboniferous , Westphalian D or Stephanian , Neuropteris flexuosa was found in the level of the Westphalian B of Northern France..... best regards bruno Link to comment Share on other sites More sharing options...
Shamalama Posted June 10, 2009 Share Posted June 10, 2009 Thus Spake Bruno! I can see what you are talking about, how the leaves attach along the whole of the base rather than just at a single point or stem. Is the fossil from the Leon area? I've seen a number of those pieces show up on e-bay but I just haven't seen any that thrill me enough to buy and pay for shipping. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...

Yes.But the thing is going to become overpriced, because the old mines are now closed for the fossil hunters, due to protection measures. Link to comment Share on other sites More sharing options...
Terry Dactyll Posted June 11, 2009 Share Posted June 11, 2009 Bruno......I see what you mean about the leaf base...... good job I put (im open to suggestions lol) and thanks again for sharing your knowledge....I havent seen this stuff before... If the mine is closed to collecting, I suppose nows the time to grab some..... Nice fossil.....Not a comon species.... 'down our way'!..... Cheers Steve... And Welcome if your a New Member...

Hi Steve Polymorphopteris is a common plant in Stephanian levels near ALES (gard ) in France ,I find it in Grand 'Combe and Grand 'Baume ...... bruno Link to comment Share on other sites More sharing options...
