Plant fossils are very common in the Glenshaw Formation. The shale preserves a multitude of plant fossil specimens, waiting to be found. Preservation can be an impression or a carbon film. These carbon films are leftover carbon from when the original organism was alive. The oxygen, nitrogen, and hydrogen disappear through various means, such as heat and pressure on the sediment. While these are extremely thin and not preserved in three dimensions, the amount of detail can be exceptional. Individual veins on leaves can be seen.
