I showed Jeffery P the Jacksboro spillway on his swing through Texas and it was my day to find plants in this otherwise marine site. At least I think that both are plants. First this piece with mm scale which I'm guessing could be Cordaites or Artisia pith. Edge view and close-up and other side Next this leaf which I think is one of the seed fern pinnules, also with mm scale other side end views and side views Does anyone agree and can you tell which of the seed ferns this could be?
I thought I posted this before but couldn't find it, maybe it was on facebook. It also seems like I've recently seen something similar but don't know where. Must take better notes... Closer in Closer still to wrinkled end on the right The image after this is looking in the direction of the arrow at the layers visible on the edge edge view
