Fossil Pine Cones In Cross-Section (Old Collection) - Washington

This is something I'd never previously seen, fossil pine cones from Saddle Mountain in Washington. This is old collection material collected many decades ago from a site that has been "collected out" for a long time.

The slab represents a forest floor that was covered by an ash flow and petrified, just like petrified wood. The layer representing this forest floor was slabbed and polished revealing several pine cones in cross section.

It's Miocene in age and the entire slab is 4.1" wide and contains at least two pine cone cross-sections.
