A lot of shells of marine organisms wind up on the ocean floor. Bones do not last on the ocean floor, they get eaten. But shells can last.
Sediments may include fossils, shells, leaves, stems, bones, and other living remains of things.
A scientist who studies fossil remains is a paleontologist. Woods, bones, and shells are the most common fossils. Paleontology tells us about ecologies of the past, evolution, and our place as humans, in the world.
Fossils form when something dies and it decays over theyears. Thenall you see are the bones. Like dinosaurs bones!
Jellyfish have no real bones, so had no fossils in the sense of the word.
Mineralization occurs in the original remains, inside the shells bones and teeth, of animals and fish. This process turns remains into fossils.
fossils?
shells, bones and fossils
Animals that become extict have fossils or bones left from when they die.
Most of what scientists know about extinct species is based on the study of bones and fossils. Scientists have studied many dinosaur bones to determine what they ate and how they lived. Fossils tell what the land was like at a given time in history.
No, because dinosaur bones called fossils are the skeleton of a dinosaur. The skeleton is there because all dinosaurs are extinct.
Tar is known as Asphalt fossils. Asphalt preserve only hard parts of organisms such as teeth, bones and the outer shells of spiecies. Countless numbers of these fossils are preserved in tar pits.
inorganic minerals replace the bones and shells in fossils. However, some recent demineralization experiments have indicated that some original connective tissue may remain, even in very old fossils.

two things- fossilization where they are fossilized for millions of years and bones don't rot.

While fossils provide an astonishing window into the prehistoric world, they also possess their limitations. From them, scientists can't ascertain the exact coloration, behavior, or vocalizations of extinct creatures. The soft tissues, such as skin and organs, often decay, leaving behind only hard structures like bones or shells. Furthermore, the emotions or social structures of these past creatures remain subjects of speculation. Fossils, though enlightening, can only unveil a fragment of the story.
