Something (such as a theory) that has become rigidly fixed. Minerals gradually enter into the cavity, resulting in a cast, which is. This is when the dead organism quickly dries out.
Process In Which An Organism Dies And Sediment Enters The Body, Filling In The Pores Of A.
A fossil formed when an animal, plant, or other organism dies, its flesh decays and bones deteriorate due to chemical reactions; A cast fossil is a type of fossil indicator. This process happens when flowing water eventually removes the organism’s bones and tissues and leaving just an impression in the sediment.
This Is When The Dead Organism Quickly Dries Out.
Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and dna remnants.

Once dry, the mold can be removed and a porcelain version of the original wax model is the result. Cast fossil ( plural cast fossils ) a fossil formed when an animal, plant, or other organism dies, its flesh decays and bones deteriorate due to chemical reactions; The mineralized sediment that fills the mold recreates the shape of the remains.
