How is a plant fossil made?

Answer 1

when it rains,water trickles down with minerals when a plant falls into some substance that doesn't erode very quickly and stays that way for years, the plant degrades and the mud/rock hardens around it and there you go.

Answer 2

When an animal or plant dies it lays in the dirt for millions of years. Over this time more and more dirt settles on top of it and compresses down harder and harder. Eventually the bones of the animal or harder parts of a plant are turned to rock or sometimes just leave an impression of themselves in a rock

Answer 3

When an animal or plant dies its remains usually rot away to nothing. Sometimes though, when the conditions are just right and its remains can be buried quickly, it may be fossilized. There are several different ways fossils are formed. Here we go through the five steps of fossilization to make a typical 'mold and cast' fossil. An animal dies, its skeleton settles on the sea floor and is buried by sediment.

An animal dies and its body sinks to the sea floor. The soft parts of the animal rot away, leaving only its skeleton. The skeleton is buried by sediment (like mud or sand) falling from the ocean above. The sea floor is an ideal place for fossilization, which explains why many fossils are marine (from animals that lived in the sea). Land animals may die and be swept out to sea to be buried in the same way. The sediment surrounding the skeleton thickens and begins to turn to stone.

The skeleton continues to be buried as sediment is added to the surface of the sea floor. As the sea floor sinks, pressure increases in the lower layers of sediment and it turns it into hard rock. The skeleton dissolves and a mold is formed.

Now buried at depth and surrounded by stone, the skeleton is dissolved by ground water. This leaves a cavity (or hole) preserving the shape of the original skeleton. This cavity is known as a natural mold. Minerals crystallize inside the mold and a cast is formed.

Water rich in minerals enters the mold, and fills the cavity. The minerals deposited in the mold form a cast of the mold. This cast has the same shape as the original skeleton, but none of its internal features. The fossil is exposed on the Earth's surface.

Millions of years later, the rock surrounding the skeleton rises to the Earth's surface (this happens during mountain building, earthquakes and other earth processes). The rock is worn away by wind and rain, and the fossil is now exposed, waiting to be found!

Answer 4

If a plant starts to grow in a rock, and then it is buried by a landslide or mudslide, rock may form around it and the plant may be trapped for a very long period of time. Then it becomes a fossil.

Answer 5

While much depends on geography and time period, a fossil is actually made of sedimentary rock, which replaces shell and bone over time and hardens. Not every animal or plant that dies becomes a fossil, in fact, it takes rare conditions for fossilization to take effect.

Answer 6

Fossils are made remains and dead bodies of plants and animals
