5 kwi 2021 · Petrified rock is a type of fossil known as a replacement fossil. Replacement fossils are replicas of things that were once alive, such as trees, sea creatures, or the bones of an animal. The living thing dies and is trapped in the ground. As it lays there, it is covered by mineral rich water.
Activity 1: researching types of rocks 1. Fossils (the remains or imprints of dead organisms) are mostly found in sedimentary rock. In nature, dead organisms are usually quickly removed by scavengers, bacteria, rotting and erosion. In some exceptional circumstances a carcass is fossilized because these natural processes are unable to work. The
Petroleum is an example of a chemical fossil and coal is a macrofossil of plant matter. Dinosaur bones and other examples of fossil bones and teeth, such as the ones from the Fossil Park, petrified wood, microbes, fossilized faeces, nests and grains of pollen are examples of body fossils.
Summary: Petrified fossils result from permineralization, the replacement of once-living matter by minerals. Solutions containing silicates, carbonates, iron or other minerals seep into the gaps and spaces between the cells, first encasing the cells and eventually replacing the cells themselves.
What Are Petrified Fossils? Petrified fossils are formed when the original organic material of a once-living organism is slowly replaced by minerals, effectively turning to stone. This occurs over an extended period of time through a process known as petrification or permineralization.
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.
