What does petrifaction mean?
Petrification is the process by which the remains or traces of an organism become stone, commonly through the gradual replacement of organic material by minerals. The resulting fossils may preserve details of an ancient plant or animal, allowing scientists to study life from the distant past. The word also has a figurative meaning: a person in a state of petrification is so shocked, frightened, or overwhelmed that they cannot move or respond. In this figurative use, it is more dramatic and literary than the everyday expression for being simply startled. Both meanings emphasize transformation or immobility, but the literal sense refers to a physical change over time, whereas the figurative sense describes a sudden psychological reaction.
The process by which organic material becomes stone, especially through fossilization; also, the resulting mineralized state.
"The specimens illustrate petrification in remarkably fine detail."
The literal meaning is most common in geology, paleontology, and discussions of fossil formation.
A figurative state of shock, fear, or immobility.
"The announcement struck the crowd with such force that everyone remained in petrification."
This use is figurative and generally more literary or dramatic than literal.
The plural is uncommon and is used mainly when referring to multiple instances of the process or state.
"The site contains several examples of fossilization and petrifactions preserved in volcanic ash."
Petrification preserves the shape of a living thing while replacing its organic matter with minerals, turning a trace of life into stone.

Where does petrifaction come from?
Petrification comes from the verb petrify, which was formed in the early 17th century from Latin petrificare, itself built from Greek petra, “rock” or “stone,” and Latin facere, “to make.” The noun entered English in the same period for the process of turning material into stone. Its figurative use for mental shock and immobility developed from the idea of a person becoming rigid like stone.
