Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.
Petrified fossils: where organic material is replaced by minerals. Mold fossils: where the shape of an organism is preserved in sediment. Cast fossils: formed when a mold fills with minerals, creating a replica of the organism. Trace fossils: records of biological activity, like footprints or burrows. Amber fossils: organisms preserved in hardened tree resin.
Cast fossils: Formed when minerals fill a mold left by a decayed organism. Mold fossils: Created when an organism's remains leave an impression in sediment that hardens into rock. Petrified fossils: Organic material replaced by minerals over time, forming a rock-like replica. Trace fossils: Evidence of an organism's activity (e.g., footprints or burrows) preserved in sedimentary rock. Carbon fossils: Organisms preserved in carbon-rich environments, like coal or oil deposits. Preserved fossils: Organisms remain intact or partially intact due to exceptional preservation conditions.
Well there are 3 types of fossils: Petrified Fossils, Molds and Cast, and Preserved Remains. Petrified Fossils are the organisms buried in the layers of sediment. Molds and Casts are the organisms, like shells, buried by sediments, in which they gradually dissolve. Preserved Remains are the organisms preserved in other substances. For example, entire organisms, such as huge elephant-like mammoths that lived thousands of years ago, have been preserved in ice. Therefore, Preserved Remains is a major type of fossil that does not form in sediments. This can be formed by decades of being stuck in the ice age and eventually falling through the ice and never getting out. Since you cant get out you get frozen! Being frozen and preserved in another type of substance in called... Preserved Remains! --Hope this could help. Thanks for reading.:)
Yes, rocks with fossils are often formed from the remains of animals. When an animal dies and is buried, its remains can be preserved in sedimentary rock as fossils over long periods of time. These fossils can provide valuable insights into the past life forms of our planet.

Fossils are formed when the remains of plants or animals are buried quickly by sediment and then preserved over time through a process called mineralization, where minerals replace the original organic material. Over thousands or millions of years, these preserved remains can become fossils through various processes like compression, impression, or petrification.

Voids left behind by once present fossils are called 'trace fossils'.
Every rocks have formed in special environment some form by lava and some form in sea, raver and lakes so the rock which is formed inside water so they have fossils of specific environment and the rocks form by lava it was hot so there were no possibility to preserved living organism.
Short spans of geologic time
Mineral replacement fossils are formed when minerals gradually replace the organic material of an organism, preserving its shape and structure. This process occurs when the organism is quickly buried by sediment, cutting off oxygen and preventing decomposition. Over time, minerals such as silica, calcite, or pyrite gradually infiltrate the spaces left behind by the decaying organic material, creating a replica of the original organism.
Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.
