What are five ways fossils are formed?

Answer 1

1) An animal dies, its skeleton settles on the sea floor and is buried by sediment. 2) The sediment surrounding the skeleton thickens and begins to turn to stone. 3) The skeleton dissolves and a mould is formed. 4) Minerals crystallise inside the mould and a cast is formed. 5) The fossil is exposed on the Earth's surface.

Answer 2

How are fossils formed?Freezing (refrigeration)-This is the best means of preservation of ancient materials. It happens only rarely. The animal must be continually frozen from the time of death until discovery. That limits the possibilities to cold hardy animals from the last ice age. There have been remarkable discoveries of mammoth and wooly rhinoceros found in ice from Alaska and Siberia. Specimens with flesh, skin, and hair intact have been found. Some of these finds suggest that they were flash frozen, with food still in the mouth and stomach.

Drying (desiccation)- Mummified bodies of animals including humans have been discovered in arid parts of the world. The soft tissues including skin and organs are preserved for thousands of years if they are completely dried.

How are fossils formed?Asphalt- In what is now downtown Los Angeles lies a 23 acre park called The La Brea Tar Pits, officially Hancock Park. Within the park are over 100 pits filled with sticky asphalt or tar. The tar pits were formed by crude oil seeping through fissures in the earth. The lighter elements of the oil evaporate leaving thick sticky asphalt.

The pits are famous for the number and high quality of Pleistocene fossils that have been pulled from the pits. The fossils date between 10 and 40 thousand years old. Asphalt is an excellent preservative. Bones, teeth, shells, the exoskeletons of insects, and even some plant seeds have been pulled from the pits.

How are fossils formed?Amber- Insects, Spiders, and even small lizard have been found, nearly perfectly preserved in amber. Picture this scenario: A fly lands on a tree branch in an area that is now the Baltic sea. While looking for food it steps in sticky sap that the tree has made to protect itself from fungal infection.

Answer 3

casts,moulds, petrification, prints and actual remains!

Answer 4

There are more than five but the most common methods are:

Petrification, Imprints, Casts, Molds, Freezing, Tar Pits, Amber, and Drying

Answer 5

That last awnser sucked...There are 6 diffrent types they are: Trace, Petrified, Mold, Cast, Whole Animal (i.e a bug encased in amber) and Carbon...film or something.

Answer 6

None
