Very interesting, but I have to be honest, I knew that the fern is a very old plant, in the mountains where I live, in the pre Italian Alps, the forests are covered with ferns, this plant is really beautiful. Listen @gavvet, I found a very interesting fossil but I'm not sure if that's what I think, given your knowledge, I'd like to show you some pictures of it, maybe on discord, to get your opinion, I do not want to expose it to the public before knowing its real identity, so I prefer to have your opinion in private. I would be very grateful, thank you!
