Transcript of Fossil Geography project

What are fossils and paleontology?
The word "fossil" comes from the Latin word fossilis, which means, "dug up".
Paleontology is the study of ancient life through fossils.
Fossils are remains of ancient animals and plants.
A fossilized object has the same shape as the original object.
If no scavengers came, then parts of the animal turned into fossils over time.
Some animals were quickly buried after their death.
Over time, more and more sediment covered the remains.
The parts of the animals that didn't rot were encased in newly formed sediment.
this forms a fossil!
The two main types of fossils
Body fossils: the preserved remains of a animal's body.
Trace fossils: the remains of the activity of an animal, such as preserved trackways, footprints, fossilized egg shells, and nests.
Fossil fuels are hydrocarbons such as coal, oil and natural gas, sourced from the organic remains of prehistoric animals and plants.
Without fossils their wouldn't be any fossil fuels!
BUT....WE NEED TO BE CAREFUL! THESE ARE RUNNING OUT AND HAVE A MASSIVE IMPACT ON GLOBAL WARMING!
How are they found?
Body fossils
Trace fossil
Importance of Fossils
Fossils are one of the most valuable sources of information about the Earth's history.
By studying fossils we can learn about how the animals: grew,what they ate, how they interacted, and many aspects of their behavior.
Fossils provide us with oil and natural gas.
Studying fossils has led to new understanding about how life evolved on earth and about diseases (both in history and in hte modern day)
Fossils also help us understand past climates including ice ages and other times that were warmer than our present climate.
They help geoscientists understand global warming and its effects
.
Living fossils
There are certain plants and animals on our planet that have not changed in millions of years.
Or that are only surviving species among a family of plants and animals that died out long ago-and these are sometimes referred as living fossils.
Examples of living fossils: horseshoe crab, neoglyphea neocaledonica, and coelacanth, plus laotian rock rat.
What is a fossil?

Are fossil fuels made with fossils?
How fossil fuels are formed.
This is a Horseshoe crab, we know about it as a result of fossils!
How fossils are formed
By: Eva Cahill
A fossil is the same shape as the organism but it is more chemically like a rock. Over a long time debris are compressed until sedimentry rock is formed.
Fossils are found in the ground and can be found by anyone! believe it or not, you can just go down to the beach and start digging, well off you pop then!
Why are they so important then?
tHANKS FOR WATCHING!!!!
What importance does it have on geography then???
Well, there are many different aspects that question... first of all it helps us to determine future and past climates, this has made a big difference on many peoples live. secondly, it has taught us allot about how organisms behaved and what they were like and how bigger size they were which nearly no other fossils could do. Finally it gets people interested in this subject which can be beneficial to geoagraphy because more people will understand ways to treat and look after the planet.
Why I chose it?

I chose it because I think that you can learn so much about it, it is like an old version of a photograph as it can tell us what happened before we were born and where/when it happened.
