@mackenzie-smith Do you know what this might be? It’s quite unlike the typical leaves you find. Almost like some sort of flowering structure.
@patrick-hsieh Off the top of my head I don’t know what the broader leaf is. The narrow one is probably in Salicaceae, either Populus (cottonwood and poplar) or Salix (willow). The stick with the fuzzies coming off of it is likely some sort of platanaceous fruit (sycamore family). It probably belongs to either Platanus (sycamore) or Macginitea (an extinct genus of sycamore). Both fruits have their own genera though (I believe its Platanocarpa and Macginacarpa respectively) since different organs in paleobotany receive their own names.
@mackenzie-smith Thanks! The sycamores seem pretty common at this locality so that makes sense, Macginitea wyomingensis is documented at this locality, theres even a nice picture of a leaf here https://www.digitalatlasofancientlife.org/learn/embryophytes/angiosperms/angiosperm-phylogeny/.
