Your fossils are so detailed, that all one has to do is close their eyes and you can see it vividly. Thanks for sharing. Link to comment Share on other sites More sharing options...

Auspex Posted November 28, 2008 Share Posted November 28, 2008 Neuropteris tenuifolia from Lievin Pecopteris sp from Macot la Plagne (Savoie ) The Lievin Neuropteris really shows the varying morphology of the pinules, and the Macot la Plagne Pecopteris is a great example of different preservation from different sites.

Auspex Posted November 28, 2008 Share Posted November 28, 2008 If found seperately, I might have thought them to be different plants!

mommabetts Posted November 29, 2008 Share Posted November 29, 2008 That is amazing, I would not have thought that they were the same, especially the one in the middle. To me it doesn't look like the same plant. Link to comment Share on other sites More sharing options...

Auspex Posted December 1, 2008 Share Posted December 1, 2008 I see that the veination of the pinnules, and how the pinnules attach to the rachis, are the keys to identity. I also see that excellent preservation is required!
