5 Red Fossil Leaves on Rock (3 species) - Montana

 
 

This is an association of five leaves from the Fort Union Formation of Montana. The color of the rock and the leaves is rather unusual, and different than most of the leaves seen from the Fort Union Formation. They were collected from a locality where a fire in a nearby coal seam "cooked" the rock at sometime in the past. This changed the color and gave it a chalky texture. There are three separate species of leaves.
