ilovethebeatles Posted May 19, 2018 Share Posted May 19, 2018 Hello all! Another question from a fossil and geology newbie. I found a bag of interesting rocks in my home today. It contained what looked like store bought rocks but I have literally no idea where they came from or how I got them. Included were two fern looking fossils and I'm not sure if they're real or not. This is probably an extremely stupid question, but I just want to make sure. Thank you! (also my apologies for the terrible lighting in the photo, I can attach more if needed) Link to comment Share on other sites More sharing options...
ynot Posted May 19, 2018 Share Posted May 19, 2018 Real, fern leafs. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Fossildude19 Posted May 19, 2018 Share Posted May 19, 2018 The ferns are real. They look like Mazon Creek nodules.

Spongy Joe Posted May 19, 2018 Share Posted May 19, 2018 Nice! Of course, these 'ferns' probably aren't really ferns. At least, the Alethopteris is a pteridosperm ('seed-fern'): an extinct group of plants that had fern-like leaves but reproduced from seeds rather than spores. The Pecopteris is more problematic, and leaves given that name probably belonged to at least three different major groups of plants - including, in a few cases, actual ferns!

doushantuo Posted May 19, 2018 Share Posted May 19, 2018 Can recommend: The emphasis of this thesis is not on macroscopical aspects,however extremely exhaustive in its treatment,but in parts outdated,and IN FRENCH(publ. 1932): On the plus side :the plates are HUGE(above:between 1/3 and 1/2 of the actual size) and razorsharp(to the right:Pecopteridium(Palaeoweichselia)defrancei) Orue(2013) has published a useful taxonomical overview of Pecopteris(in Spanish),which helps in deciphering which parts of the comprehensive thesis to the right(below) might be outdated. As has been repeatedly pointed out,in Paleozoic plants macroscopical anatomy isn't TOO reliable a systematic criterion(by itself) Link to comment Share on other sites More sharing options...
