Here's a part counterpart of a leaf I split from the shales of the Allenby Formation at a road cut north west of Princeton, BC. This is the main collection site along the road that runs along the eastern shore of the Tullameen River. Has anybody seen a similar leaf and been able to identify it from Paleocene or Eocene deposits?
The veins remind me of Tsukada sp. but this leaf is much narrower. I've also considered a species of Betula (Beech) but again either the leaves are too wide or the serrated edges are larger than what's indicated on this leaf. I'm down to a species of Alnus (Alder) but still can't nail it down. Being a vertebrate guy I need a little help here please.
