hitekmastr Posted August 30, 2012 Share Posted August 30, 2012 I've been pondering this fossil from St. Clair and it looks like a "cupule" that encloses a seed or spore and I'm thinking that it might be cupules at the end of a node - maybe archaeopteris. Is anyone familiar with these fossil plant cupules who might shed some light on this? One of the very surprising things we're learning about fossil plants (Pennsylvanian) is that many of the ferns and horsetails had different shaped leaves or leaf configurations on the same plant, such as the microphylls on the trunk, cupules that enclosed seeds, and young round leaves versus older elongated leaves (neuropteris for example). Still learning about paleobotany at St. Clair where we've been collecting - fascinating. Link to comment Share on other sites More sharing options...
Trevor Posted August 30, 2012 Share Posted August 30, 2012 Hello hitekmastr! I have no idea what it is, sorry. I dont collect plant fossil, but i want to. I want to tell you that that is a nice find and i wish you luck on finding an ID. Good luck... : ) Link to comment Share on other sites More sharing options...
Auspex Posted August 30, 2012 Share Posted August 30, 2012 So much of the coal-swamp flora was named from unassociated bits that there can be many parts of the same plant with different names. Clear, attached associations are pretty rare!

Herb Posted August 31, 2012 Share Posted August 31, 2012 I don't know what it is, but Archaeopteris is usually associated with the Devonian. It is a really nice specimen regardless.
