Examples of permineralization in the following topics:
-
- Fossils can form under ideal conditions by preservation, permineralization, molding (casting), replacement, or compression.
- The most common method of fossilization is permineralization.
- Fossilized dinosaur bones, petrified wood, and many marine fossils were formed by permineralization.
- However, replacement can occur without permineralization and vice versa.
- These fossils from the Road Canyon Formation (Middle Permian of Texas) have been silicified (replaced with silica), which is a form of permineralization.
-
- Permineralization is a process of fossilization that occurs when an organism is buried.
- Small-scale permineralization can produce very detailed fossils.
- For permineralization to occur, the organism must be covered by sediment soon after death, or soon after the initial decay process.
- The bones of this Tyrannosaurus rex were preserved through the process of permineralization, which suggests that this organism was covered by sediment soon after death.
