Terry Dactyll Posted November 22, 2009 Share Posted November 22, 2009 Bruno..... Really nice examples.... and not a very common find on the places that I have hunted for plant fossils... I think this may be my only example and I think its Neuropteris and the seeds are arranged around the outside edge of the indivdual leaf's... Cheers Steve... And Welcome if your a New Member...

Hi Steve ,Neuropteris are not true ferns ,they have seeds ,likely trigonocarpus ,they are pteridospermophyta ,your fern is a true fern ,with fertile foliage likely Oligocarpia ,it is a filicophyta like our modern ferns .....

Shamalama Posted November 22, 2009 Share Posted November 22, 2009 Are those seeds or spore sacs? Very interesting fossils, something else for me to keep an eye out for. -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...
