A Trip Through Geologic Time

Clues from Fossils Fossils give us information about living things in the past.

Fossils Fossil are the preserved remains or traces of living things. They form when living things die and are buried by sediment. They are usually.

Fossils Essential Questions: What are fossils and how are they formed?

Key Words Fossil: the preserved remains or traces of living things Paleontologist a scientist who studies fossils to learn about organisms that lived long.

Fossils. Essential Question How can fossils be used to help explain what happened in the past?

Remains of once living organisms. Form from decay and are buried by sediment. Sediment hardens into rock and preserves the shape of the organisms.

A Trip through Geologic Time: Fossils

*Fossils are preserved remains or traces of living things. *Most fossils form when living things are buried by sediments. *These slowly harden into rock and preserve the shape of the organism. *Scientists that study fossils are paleontologists .

*Fossils are usually found in sedimentary rocks. *When an organism dies, its soft parts often decay quickly, leaving only the hard parts to fossilize. *Ex: Bones, Shells, Teeth, or Seeds.

*KINDS OF FOSSILS. *PETRIFIED FOSSILS *Fossils where minerals replace all or part of the organism. ie: Petrified Wood *When the object is buried by sediment, water rich in minerals seeps into its cells; when the water evaporates, the minerals are left behind. *KINDS OF FOSSILS.

*KINDS OF FOSSILS. *MOLDS AND CASTS * A mold is a hollow area in sediment in the shape of an organism or part of an organism. *A cast is a copy of the shape of the organism. *KINDS OF FOSSILS. http://www.classzone.com/books/earth_science/terc/content/visualizations/es2901/es2901page01.cfm

*KINDS OF FOSSILS. *CARBON FILM FOSSILS. *Carbon films are extremely thin coatings of carbon on rock that form when materials that make up an organism become gases and escape leaving only Carbon behind. *KINDS OF FOSSILS.

* TRACE FOSSILS. *Trace Fossils provide evidence of the activities of ancient organisms. For example – footprints, animal trails, or animal burrows *KINDS OF FOSSILS.

* PRESERVED REMAINS. *Preserved Remains are formed when an organism is preserved with little or no change For example when organism become trapped and preserved in tar, amber (tree sap), or ice *KINDS OF FOSSILS.

*To learn what past life forms were like *WHY STUDY FOSSILS? *To learn what past life forms were like *To classify organisms in the order in which they lived *To prove extinct species existed!

*WHY STUDY FOSSILS? *All the information scientists have gathered is called the fossil record. *Shows how groups of organisms have changed over time. * Helps support the Theory of Evolution

One last thing… INDEX FOSSILS

*Scientists use index fossils to match rock layers. *MUST BE WIDELY DISTRIBUTED (spread out) and ONLY EXISTED BRIEFLY. *They are useful because they tell the relative ages of the rock layers they are found in.

*Evolved more than 500 million years ago. *INDEX FOSSIL-THE TRILOBITE. *A group of hard –shelled animals whose bodies had three distinct parts . *Evolved more than 500 million years ago.
