Permineralization is a process of fossilization of bones and tissues in which mineral deposits form internal casts of organisms. Carried by water, these minerals fill the spaces within organic tissue. Because of the nature of the casts, permineralization is particularly useful in studies of the internal structures of organisms, usually of ...
Just what form the silica initially takes is still a topic of research. There is evidence of initial deposition as opal, which then crystallizes to quartz over long time periods. [2] [9] On the other hand, there is some evidence that silica is deposited directly as quartz. [8] Wood can become silicified very rapidly in silica-rich hot springs. [10]
Small scale permineralization can produce very detailed fossils. [73] For permineralization to occur, the organism must become covered by sediment soon after death, otherwise the remains are destroyed by scavengers or decomposition. [74] The degree to which the remains are decayed when covered determines the later details of the fossil.
Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrifaction or petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Skeletonization is the state of a dead organism after undergoing decomposition. [1] Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed.
