Found this gorgeous little fella today in some Triassic sediment that had eroded out of a cliff near here. It was in a layer that also had a lot of Dicroidium leaves. I thought it might be a cupule, just looking for an accurate ID. Cheers,

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.
