Summary

Description
English: Fossil wood from the Miocene of Montana, USA.

Permineralization is a common preservation style for fossil wood - it is frequently nicknamed "petrified wood". Permineralization refers to the small-scale porosity of wood or bone being filled with minerals as groundwater percolates through after burial. The most common permineralization mineral is quartz.
