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although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.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?
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.
Fossils are physical evidence of prehistoric life that is preserved in the Earth's crust. These remnants can include the remains of plants, animals, and other organisms that lived long ago, providing valuable insights into the history of life on our planet. The study of fossils helps scientists understand the evolution and biodiversity of life over millions of years.
Ophiolites, pieces of oceanic crust that have been stranded on land, have been dated to 3.8 billion years of age in Greenland. Most oceanic crust in the oceans today dates from the Jurassic or younger, <200 million years old.
Certain minerals, rocks, and elements are examples of materials that were not part of living things. These materials form naturally in the Earth's crust through geological processes like cooling of magma or precipitation from solution.
Rock fossils form in sedimentary rocks because the process of fossilization usually involves the burial and preservation of organic material in layers of sediment. Igneous rocks form from molten magma, which would destroy any organic material present, making it unlikely for fossils to be preserved in them. Sedimentary rocks, on the other hand, accumulate over time and provide the conditions necessary for the preservation of fossils.
They are called fossils.

Fossils
Fossils are the remains of living organisms that have been preserved in the Earth's crust. This includes bones, shells, imprints, or traces left behind by plants and animals that lived in the past. Fossils provide valuable information about the history of life on Earth and how organisms have evolved over time.
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.
Subfossils
Some examples of remains preserved in the Earth's crust include fossils of plants, animals, and microorganisms, as well as minerals, shells, and even ancient human artifacts. These remains provide valuable insights into the history of life on Earth and past geological processes.

A fossil is not considered a mineral because it is made up of organic materials (such as bone or shell) that originated from living organisms. While minerals are formed through geological processes without the involvement of living organisms, fossils are the remains or impressions of once-living organisms that have been preserved in the earth's crust.
