WebJun 8, 2024 · Replacement occurs when the original shell or bone dissolves away and is replaced by a different mineral; when this occurs with permineralization, it is called petrification. In compression, the most common form of fossilization of leaves and ferns, a dark imprint of the fossil remains. WebDuring petrification of wood, the walls of every cell are replaced by a dissolved rock solution, such as a silicate or limestone. This has to happen before the cells decay. What is the longest that the petrification process could take before the log decayed away? And what is the shortest time in which the process could occur in optimum conditions?

WebApr 16, 2024 · How does petrification happen? Petrified fossils form when minerals replace the structure of an organism. This process, called permineralization, occurs when groundwater solutions saturate the remains of buried plants or animals. As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly … In marine environments, pyritization occurs when organisms are buried in sediments containing a high concentration of iron sulfides. Organisms release sulfide, which reacts with dissolved iron in the surrounding water, when they decay. This reaction between iron and sulfides forms pyrite(FeS2).
