When minerals replace bone (organic matter), the type of fossil form is Petrification.
Petrification types of fossils are abundantly found in Gondwanaland. Both plants and animals are subjected to this process, particularly those having hard tissues like bones and vasculature.

What are the remains of living things that have been preserved in the earth's crust?
Fossils are the remains or traces of living things that have been preserved in the Earth's crust. They can include bones, shells, imprints, or tracks left behind by organisms that lived long ago. Fossils provide valuable information about past life forms and can help scientists understand the history of life on Earth.
What are the remains of living things that have been preserved in earth crust?
Fossils, although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.There are a number of different fossilization processes. See this link :How are Fossils Formed?
Is calcium the main substance that forms bones?
Calcium and phosphorus are the two main minerals in bone.
What type of fossil forms when pore spaces of the original hard parts of an animal are filled in by minerals?
A cast fossil is formed when minerals fill in an impression left by an organism.
Are fossils fake dinosaur bones made out of plaster?
The fossils displayed in mueseums are usually plaster to prevent the originals from being damaged. The real ones are kept in a lab, most are at the American Mueseum of Natural History. There, they can be studied.
How many different ways can fossils form?
When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber. Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolite are trace fossils - they show us how an animal lived.
What are the remains of living things that have been preserved in the earths crust?
Fossils are the remains of living things that have been preserved in the Earth's crust. These can include bones, shells, plants, and traces of organisms such as footprints or burrows. Fossils provide valuable information about ancient life forms and environments.
One kind of fossil forms from the body parts of organisms. What is another kind of fossil?
Another kind of fossil is a mold or cast fossil, which forms when an organism's remains decay and leave an impression in the surrounding sediment that is later filled with minerals. Another type is a trace fossil, which is evidence of an organism's activity, like footprints or burrows, preserved in rock.
What are examples of fossils?
Examples of fossils include preserved bones, teeth, shells, plants, and footprints. These remains provide evidence of past life forms and give insights into the Earth's history. Fossils can range from tiny microscopic organisms to large skeletons of dinosaurs.
Are rocks and bones similar?
Rocks and bones are similar in that they are both solid materials composed of minerals and can be found in various forms. However, they differ fundamentally in their composition and origin; bones are organic structures primarily made of collagen and minerals like calcium phosphate, while rocks are typically composed of inorganic minerals. Additionally, bones are part of living organisms, serving biological functions, whereas rocks are non-living and form through geological processes.
What are preserved remains of a living thing called?
Preserved remains of a living thing are called fossils. Fossils can be bones, shells, imprints, or traces of ancient organisms that have been preserved in rocks. They provide valuable information about past life forms and environments.
