Crazyhen Posted February 21, 2019 Share Posted February 21, 2019 This is said to be a Triassic tree fern from Guangxi, China. It measures about 31cm in diameter. Any idea if it is a tree fern or other fern? 2 Link to comment Share on other sites More sharing options...
ynot Posted February 21, 2019 Share Posted February 21, 2019 Even though there is no scale to tell how big it is. It looks like a big piece so had to come off a big plant. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Rockwood Posted February 21, 2019 Share Posted February 21, 2019 This look often is hard to pin down. It is sometimes suggested to be fern, and sometimes palm is preferred. I don't have the expertise to call this one. 1 Link to comment Share on other sites More sharing options...
verydeadthings Posted February 21, 2019 Share Posted February 21, 2019 Nice specimen! If it's Triassic it wouldn't be a palm (Arecaceae), they're angiosperms and evolved in the Cretaceous. Along with true ferns like the tree fern group Marattialies, there were other major plant groups around, for example seed ferns (Spermatophyta), early gymnosperm conifers, and others. I don't know much about identifying petrified wood, though, just throwing out some options 2 Link to comment Share on other sites More sharing options...
abyssunder Posted February 21, 2019 Share Posted February 21, 2019 May be close to Psaronius? 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
