General Introduction of Fossils
- Fossil plants or animals are physical evidence of the existence of plants.
- The most common and obvious fossils are the remains of animal skeletons. Other fossils that also contain evidence of previous fauna include leaf prints, footprints and footprints, droppings, and original casts.
- Microscopes are microscopic skeletons of pre-existing plants or animals and require an optical or electron microscope to examine them closely.
- The fossil record reveals a tiny fraction of the organisms that lived on Earth: many did not have skeletons or other solid parts that could be preserved; many did not survive the fossilization process when skeletons and tissues are replaced by minerals; and many of them were subsequently destroyed by chemical or physical processes such as recrystallization, metamorphism or erosion.

Definition:
Fossils Organisms are the remains of plants and animals whose bodies were buried in the soil in the form of sand and mud at the bottom of old seas, lakes, and rivers. Organic life has any preserved traces that are usually more than 10,000 years old. The soft parts of the body burn out immediately after death, but hard parts like bones, shells, and teeth can be replaced by minerals that become harder. In very rare cases, soft parts of the body such as feathers, plant ferns, or other evidence of life such as footprints or dung can be preserved.

Why we need Research over Fossils?
- Fossil Organism Provides important evidence for biological growth and for plants and animals to adapt to their environment.
- Biological evidence provides a record of how animals evolved and how this process can be illustrated by the tree of life. This shows that all species are related to each other.
- Fossil organism Nature can explain to us how the world and our environment have changed since when the world, one continent, now large, is connected at the same time.
- The material can be used for the stone day. From the beginning, various forms of nature have appeared in the rock of different times, enabling geologists to use fossils to understand the history of the earth.
- Fossil is one of the most important tools for age interaction. Ammonites, for example, produce the best fossils for stratigraphy i.e., fossil fuels can be used to determine two years of two or more rocks, or strata, located at different locations in the same country and it is another place in the world.

Process of Fossil Formation:
Fossils are the process of transforming a plant or animal into a fossil. These small structures and a small part of the plants that existed six hundred years ago are still preserved as fossils. This may come as a surprise considering the millions of fossils collected over the years and the fact that they still contain billions of rocks. Plants and animals that normally turn into fossils and suffer and, with a few exceptions:-
Several Important Processes
- The weak things that exist during the decay of life leave only the “hard things” (bones, shells, teeth).
- The hardest parts can be taken and broken. This can lead to inaccurate fossil record information.
- It is more common to find shells or bones than to have a complete skeleton. Third and most important, solid cells are buried and replaced.
- In many cases, this involves the destruction of the original resulting in complex processes such as minerals that are slowly refined and replaced by new ones.
- It often cleans a difficult area without being replaced by new ones, leaving only a feeling or image of the original animal. If this alteration is filled with soil which was later cemented with stones then the first animal is cast.
- These models are just a few of the things that can transform living things into rocks.

Each process usually follows the 6 previously mentioned steps: decay, removal, and burial. Consider using the same method to bake two cakes and use a different set of ingredients for each cake. In our case, cake cakes and fossilization are the way to go.
Fossils Invertebrates:
- Invertebrates form groups of animals without thorns. In the fossil record, the diverse individuals that represent all living things (snails, snails, crabs, glitter) are common to most humans and are more concerned with the sheer number of endangered species lost millions of years ago.
- Half a billion years ago in the corporate era of this company, some of these people lived without interruption. Many of them made hard shells made from mineral calcite or aragonite. Fortunately, Aeons Beach has been continuously inhabited by a large number of these shellfish, resulting in an incredibly diverse fossil record.
- Among the first variants to appear in the fossil record were trilobites and it was a marine arthropod that spread across the ocean floor during the Paleozoic period. Other early invertebrates include archaeologists and interstitial sponges, which produced the same broad leaves as today’s corals, Corals in the past had many shapes and did not exist in modern oceans.

Fossils Vertebrates:
- Devonian is a critical period in the evolution of Versatile.
- Due to the huge evolution of marine fish during this period, the Devonian is often referred to as the “Fish Age”.
- This region can also be divided into different tooth-shaped biological regions (see Biological Chronology).
- These small sea vertebrates are characterized by well-known vertebrate carriers and their teeth. Other vertebrates include sharks, reptiles, amphibians, and animals that migrated from the sea to land.

Modes of Preservation
There are Methods of care the eight vital categories are commonly known. Although these categories are well defined, a particular creature can fall into several categories or avoid them all. As a result, these categories should be considered as a way of care rather than a shoebox where all living things should be included. When thinking about organic varieties and methods of care, There is more important to consider the lack of biological information or the existence of more specific classifications than the organization. In addition to this consciousness, other creatures also have biological substances that protect ancient creatures (human bodies):-
1. Unaltered remains: The original fabric may be slightly deformed whole, dry, frozen, or preserved in amber.
2. Compression- impression: 2-dimensional flattened organic matter with or without film.
3. Mold−cast: 3-dimensional care where reality does not exist
4. Recrystallization: Aragonite returns to calcite or can be converted to dolomite.
5. Permineralization: Mineral fluid affects the cells of the body without losing real substances (except for the contents of the cells).
6. Dissolution−Replacement: The original substance dissolves and is replaced by another mineral. Organic body in which the body of an organism no longer exists, but some evidence of its existence remains.
7. Molecular fossils: The molecules that remain in the geographical record have no trace of other organisms. Some examples of biochemical degradation products of chlorophyll, flavonoids, collagen, DNA, lipids, and proteins.
8. Trace fossils: There are traces, pits, and other evidence that there were creatures.
