What is fossilization in detail?
When bones, or other dense living material is buried, over thousands of years as it decays it leaves spaces where minerals can gather. As the bone/ivory/shell/whatever, decays it is slowly replaced with mineral deposits that when the substance is fully decayed will fill in the hole that would have been left, and that mineral form is the fossil.
How fosils are made?
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.
How are insects preserved for scientific study and research purposes?
Insects are preserved for scientific study and research purposes by methods such as drying, freezing, or using chemicals like ethanol or formaldehyde to prevent decay and maintain their physical structure. These preserved specimens can then be studied under microscopes or used for genetic analysis to learn more about their biology and behavior.
How can bugs be effectively preserved?
Bugs can be effectively preserved by carefully collecting and handling them, using proper preservation techniques such as drying, freezing, or using chemicals, and storing them in a cool, dry place to prevent decay.
Any trace of a ancient organism preserved in rock is called?
A fossil. Fossils are the preserved remains, impressions, or traces of ancient organisms that provide evidence of past life on Earth. They can include skeletons, shells, footprints, and more.
How are fish often preserved?
The most common type of fossil preservitation is with alteration. The original organic material is partially or totally changed into new material. There are four common types of preservation with alteration including carbonization, permineralization, recrystallization, and replacement. These processes involve a chemical reaction with the organism and its surrounding.Carbonization is a chemical reaction when water transforms the organic material of plant or animal to a thin film of carbon. Nitrogen, hydrogen, and oxygen are driven off as gases, leaving an outline of the organism. Organisms often preserved by carbonization include fish, leaves and the woody parts of plants.-Des K

What happens to animals after they die and other animals does not eat them?
Bacteria and or fungi decompose their bodies. Alternatively their bodies could be preserved in some way such as mineralization in fossils.
Are fossils examples of organic matter and why?
Yes, fossils are examples of organic matter because they are the preserved remains or traces of once-living organisms. Fossils can include bones, shells, teeth, and other organic materials that have undergone a process of mineralization or replacement with inorganic materials to become stone-like structures.
What does preserved fossil mean?
Fossils are preserved in two main ways: with and without alteration. Preservation with alteration includes carbonization, petrifaction, recrystallization and replacement. Preservation without alteration includes the use of molds and the collection of indirect evidence. Carbonization Carbonization often occurs in the preservation of plants and soft organisms. The remains of the plant or animal are crushed beneath the weight of the rock. The gases, including hydrogen, nitrogen and oxygen, are off gassed through the process of heat and compression. What is left behind is a carbon film, an impression of the former living thing. Petrifaction Sometimes referred to as permineralization, petrifaction occurs when a porous material such as a bone or shell becomes filled with preserving material such as calcium carbonate or silica. The original shell or bone becomes buried below the ground and water penetrates the surface. The groundwater contains the calcium carbonate that fills the empty spaces in the material, which over time, hardens and fills the pores full of minerals that preserve the item. Recrystallization Recrystallization often occurs in shell fossils and is the process by which the small molecule crystals inside a shell often formed of one type of calcium carbonate can transform to another type of calcium carbonate. This stabilizes the shell and turns it into a fossil. Replacement Occurring in both shellfish and wood, replacement is when the atomic composition of the original living thing is replaced cell by cell by a new chemical structure. Typically, the chemical that replaces the original is determined by the groundwater the fossil is lying in. A common type of replacement is silification. This is when the original living remains are replaced with silica as in the case of petrified forests. Casting Casting and molding are an indirect way of preserving fossils. In this case, indirect means that the chemical composition of the organic matter does not change, rather it lays in a substance that makes an impression of the matter. Common examples include castings of fern leaves and snail shells. Trace Fossils Trace fossils are another type of indirect preservation of fossils. Examples of trace fossils are footprints and trails. Dinosaurs and other prehistoric animals moved through the undergrowth and along top soil that was later covered with other debris. In some cases their tracks were preserved and can be dug up and cut out of the ground. Another example of a trace fossil is animal dung. Preserved, fossilized dung provides fossil experts with evidence of ancient food sources and the structure of prehistoric digestive system.

What is fossilized poop called?
Fossilized poop is called coprolite. It is formed when feces undergoes a process of mineralization and becomes preserved in rock. Coprolites can provide valuable insights into the diet and digestive processes of ancient animals.
Are rocks that contain preserved plant and animal remains?
Rocks that contain preserved plant and animal remains are called fossils. Fossils can provide valuable information about past life forms and environments on Earth. They are typically formed through the process of mineralization, where the remains are gradually replaced by minerals in the surrounding rock.

Over thousands or millions of years, these preserved remains can become fossils through various processes like compression, impression, or petrification.
What benefits result from mitral valve replacement?
Patients treated by mitral valve replacement for mitral insufficiency can expect relief of symptoms. Improvement in myocardial function is not likely, but the current status is preserved.
Carbonized remains of plants and animals?
Carbonized remains are the preserved remnants of plants and animals that have undergone a process called carbonization, where organic material is transformed into a carbon-rich residue. This carbonization process can occur naturally due to high pressure, heat, and lack of oxygen, resulting in the formation of coal, oil, and natural gas deposits. These carbonized remains provide valuable insights into past ecosystems and can be used as fossil fuels for energy production.
What does carbonized fossils mean?
Carbonized fossils are fossils that have been preserved through a process called carbonization, where the original organic material of the organism decomposes, leaving behind a thin film of carbon. This carbon film retains the shape and structure of the organism and can provide information about its original composition.
