What does petrified mean in biology?

Petrification is when a live organism becomes gradually turned into a stone. The scientific process of petrification involves the very slow process of minerals saturating an organism — which can be a plant or animal — and filling its pores and cavities with a hard stone.

What happens when an organism becomes petrified?

The sediment cements together and becomes rock with the organism or part inside. Petrification happens when mineral solutions remove the original organism or part and replace it with new minerals. The replacement of the original materials is generally a very slow process.

What is a petrified animal?

Petrifaction (also known as petrification) is a type of fossilization which leaves living organisms preserved as a type of stone. When an organism dies in an environment that lacks oxygen, for instance if it was covered by ash from a volcano, it is deprived of an environment that is conducive to normal decay.

What means petrification?

1 : to convert (organic matter) into stone or a substance of stony hardness by the infiltration of water and the deposition of dissolved mineral matter. 2 : to make rigid or inert like stone: a : to make lifeless or inactive : deaden slogans are apt to petrify a man’s thinking — Saturday Rev.

Why does petrification occur?

Petrified wood forms when fallen trees get washed down a river and buried under layers of mud, ash from volcanoes and other materials. Over millions of years, these minerals crystallize within the wood’s cellular structure forming the stone-like material known as petrified wood.

What causes petrification?

Petrified fossils form when minerals replace the structure of an organism. This process, called permineralization, occurs when groundwater solutions saturate the remains of buried plants or animals. As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly decays.

What causes something to petrify?

It forms when plant material is buried by sediment and protected from decay due to oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silica, calcite, pyrite, or another inorganic material such as opal.

Are there petrified animals?

At least it was a quick death. Scientists have discovered that ancient animals preserved in the famous Burgess Shale fossil deposit were killed by a mud slurry that buried them so deep their whole bodies were petrified.

How does petrification occur?

How is something petrified?

In geology, petrifaction or petrification (from Ancient Greek: πέτρα, romanized: pétra, lit. ‘rock, stone’) is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.

Are petrified remains of plants and animals?
