Hi, I found these in the Carbonado Formation Washington State. 42 - 47 million years ago. Eocene under a coal seam.
I found this bark of some mysterious looking tree. Around the same rock were tons of leaves, all similar to one species (except one leaf which I will also include). I am hoping people can identify the family of tree for me.
I also am posting some strange "cattail" / "horsetail" like stem / leaf because this could possibly be a branch from this tree.
disclaimer: I am still trying to figure out my phone. The last photo is more clear, larger and detailed. The only difference was, I held my phone sideways. Maybe this is what I will do in the future.
First I will post the bark
