This petrified wood specimen displays evidence of a possible wormhole.
Petrified wood is formed when plant material gets buried by sediment which causes it to be protected from oxygen and other living things that would cause it to decay. Over time, dissolved solids carried in groundwater flow through the sediment causing the plant material to be replaced with mineral and other non-living materials. This creates a fossil of the original plant material.
