A fossil is the remains or evidence of any creature or plant that once lived on the Earth.

The word fossil comes from the Latin word “fossilis” which means “dug up”.

The animal must be continually frozen from the time of death until discovery.
Some were found flash frozen, with flesh, skin, and hair.
Some were even found with food still in the mouth and stomach! Eeewwwww!

(An Edmontosauraus mummy)
Where’s
My mummy?
Mummified bodies of animals including humans have been discovered in dry
Parts of the world. The soft tissues including skin and organs are Preserved for thousands of years if they are completely dry.

In Los Angeles there is a 23 acre park Called the La Brea Tar Pits.
There are Over 100 pits filled with sticky asphalt. The tar pits were formed by oil seeping Through cracks in the earth.
The oil
Evaporated leaving a think sticky
Asphalt. The pits are famous for the
Fossils that have been pulled from them.
The fossils are
Between 10 and 40
Thousand years old!

A fly lands on a tree branch while looking for food and steps into sticky sap the tree has made.
As the fly struggles to escape it becomes covered in the sap until it suffocates.
The tree eventually dies and falls into the nearby swamp.
The tree becomes a coal deposit after millions of years and the sap with the fly inside is hardened into amber.
Hey! That’s
Uncle Buzz in there!

Does this
Carbon make me look flat?
Insects,
Plant leaves, parts of fish, reptiles and marine invertebrates decompose leaving behind only the carbon. This carbon creates an impression in the rock outlining the fossil.
This is a real bee carbon imprint.

This is the most common form of fossil preservation. Minerals
Fill the spaces and crystallize. The shape of the plant or animal
Is preserved as rock. Sometimes the original material is dissolved
Away leaving the form and structure but none of the organic
Material remains.

Most rocks found in and on the Earth’s crust are sedimentary rocks.
They form when silt and sand collect and harden. Over millions of years
The result is thick layers of rock. In areas like the Grand Canyon, you can
See the layers. These layers are known as strata.

WOW!!! Did you know …To tell the age of most layered rocks, scientists study the fossils the rocks contain. Fossils give evidence that helps determine what happened in history and when it happened.

Paleontology is a branch of biology that studies
The forms of life that existed in former
Geologic periods, mainly by studying
Fossils and the rocks surrounding them
Most of the overlying rock is removed using large tools like
Picks and shovels but part of the rock that is closest to
The fossil is removed with smaller tools like trowels,
Hammers, whisks, and dental tools. Fossils have
To be treated very carefully to avoid
Breaking them.
