Petrified wood can have a distinctive smell due to the minerals and compounds that have replaced the organic material during the fossilization process. This can release odors when the petrified wood is broken or exposed to air.
Could a glacier leave behind petrified wood?

Petrified wood can be up to 10 times heavier than regular wood because the organic material in the wood is replaced by minerals during petrification, increasing its density.
Does petrified wood opalize?
Yes, petrified wood can opalize. Opalization occurs when silica-rich water seeps into the pores of the wood and replaces the original organic material with opal, resulting in a fossilized wood with opal instead of its original cellular structure. This process can create beautiful opalized specimens.
How hard is petrified wood?
