permineralized remains
Fossils are rarely found inside individual rocks, but if they are, it will be inside boulders that were originally part of a layer of mudstone or sandstone (sedimentary rock). Scientists refer to this type of rock as "Fossil bearing" Joan Wiffen of New Zealand was a Paleontologist who discovered individual dinosaur bones inside massive mudstone boulders in a stream.
The fossilizing process that replaces organic matter with silica or calcite is called permineralization. In this process, minerals such as silica or calcite fill in the pore spaces of the original organic material, creating a fossil with fine details preserved.
Mineral deposits left behind that fill in the open spaces created by weaknesses in rock formation are called veins. Veins are formed through the process of hydrothermal fluids carrying minerals that solidify within cracks and voids in the host rock. This creates concentrations of minerals that can be economically significant for mining purposes.
A beaker of water. Fill the beaker to a certain point, put the fossil in the water and see how many ml the water goes up to. The difference between the original fill line and the fill line after dropping the fossil in is the volume in ml.
Silica cement: formed from the precipitation of silica (quartz) minerals in the pore spaces of the sandstone. Calcite cement: composed of calcium carbonate minerals, such as calcite or aragonite, that fill the voids within the sandstone. Clay cement: consists of clay minerals, such as kaolinite or illite, that have been deposited and cemented in the sandstone over time.
A cast fossil is formed when minerals fill in an impression left by an organism.
Permineralized fossils form when solutions rich in minerals permeate porous tissue, such as bone or wood. Minerals precipitate out of solution and fill the pores and empty spaces.

An object that was repllaced by rock so the fossil is now 3D.
The inter molecular spaces
The most common method of fossilization is permineralization. This occurs when minerals in groundwater fill in the empty spaces of organic material, creating a fossilized replica of the original organism. Over time, the minerals in the groundwater harden and preserve the organism's structure.
A cast fossil is formed when an organism dies and leaves an impression in sediment. Over time, this impression can fill with minerals, creating a replica of the organism's shape. The original organism then decays or is washed away, leaving behind the cast fossil.
No, a cast fossil is not the same as a carbonized fossil. Cast fossils are formed when minerals fill in the cavity left by a previously existing organism, while carbonized fossils are formed when organic materials are compressed and heated, leaving a carbon residue of the original organism. Both types of fossils preserve the shape of the organism, but through different processes.
The property of molecules that allows gases to fill the spaces available to them is their high kinetic energy. Gas molecules move freely and rapidly in all directions, spreading out to fill the container they are in due to their continuous random motion.
Mineral deposits left behind that fill in the open spaces created by weaknesses in rock formation are called veins. Veins are formed through the process of hydrothermal fluids carrying minerals that solidify within cracks and voids in the host rock. This creates concentrations of minerals that can be economically significant for mining purposes.
