                            a rock created by petrifaction; an organic object infiltrated with mineral matter and preserved in its original form 
                                                            
                                                     
                        
                                                
                        
                        
                            a fossilization process whereby inorganic matter dissolved in water completely replaces original organic mater, converting it to a stony substance.
                                                            
                                                     
                        
                                                
                        
                        
                            a type of preservation in which mineral matter infills intercellular spaces and replaces the cell walls; compare to permineralization and silification
                                                            
                                                     
                        
                                                
                        
                        
                            The preservation of organisms where a mineral in-fills intercellular and intracellular cavities and also replaces the organic material of cell walls.
                                                            
                                                     
                        
                                                
                        
                        
                        
                                                
                        
                        
                            or petrification: the process of turning organic materials into rock by the replacement of the organic matter with minerals.

                            In geology, petrifaction or petrification is the process by which organic material is converted into stone or a similar substance. It is approximately synonymous with fossilization. Petrified wood is the most well known result of this process.
