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.
Petrified fossils: where organic material is replaced by minerals. Mold fossils: where the shape of an organism is preserved in sediment. Cast fossils: formed when a mold fills with minerals, creating a replica of the organism. Trace fossils: records of biological activity, like footprints or burrows. Amber fossils: organisms preserved in hardened tree resin.
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
petrified
The 5 types of fossils are ...Imprint Fossils- an organism leaving an imprint on sediment that later hardens into rock.Mineralization Fossils- when minerals replace wood or bone to create a piece of petrified wood or a mineralization bone fossilsFrozen Fossils- when something like an animal gets taped in ice and remains their frozenCast Fossils- when it fills up a hollow moldfossils in amber- when an insect gets stuck in amber
Five types of fossils found in rocks are petrified fossils (minerals replace organic matter), mold fossils (imprint of an organism), cast fossils (mold filled with minerals), carbon films (thin layer of carbon residue), and trace fossils (evidence of organism's activity).
Fossils can be formed by:MummificationPetrificationDesiccationRelated question on Answers.com:How are fossils formed?
freezing (refrigeration), drying (dessication), asphalt, amber, carbonization (distillation), permineralization
In what ways are fossils useful to geologist?

we dont know?
e each fossils
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
Yes.
