What is the Multidisciplinary pursiut to reconstruct as much as possbile about the past?
|
Paleioanthropology---DUUUUH FOO!!
|
|
|
Why is Paleoanthropology like CSU Prehistory!?!?!?!?!

ANY material remains
|
|
|
What do PALEontologists analyzzzzze?
|
Faunal remains (BAMBIEEE IS A FAUN :)
|
|
|
Bodies, Fossils, Artifacts.......
|
Provide info about the past aaaand show culture behaviors--that reveal through TIME
|
|
|
Natural Mummification isssss
|
(GROSSSZ!!) A preservation-where organic materials remain presereed in SPECIAL EDDDDDD CONDITIONS
|
|
|
What is protection from the elements (for mummification)
|

The molecules making up the original object (great uncle harry) are dissolved and the spaces left behind are filled with other minerals is what...
|
Fossilization
|
|
|
That nasty fish jewlery example of the waxing that is another way of remembering fossils is a part of whhhhat
|
Fossilization!!! :D
|
|
|
WHAT is being dated!? (NOT baker!! hahahahaha!!! ;P)
|
The object itself --Direct dating
Surrouding materials-----Indirect dating |
|
|
What the heck is relative dating?!?!?!
|
Places find in sequence but doesnt provide an actual estimate in the numbbbaaaa of years! FOOOO
|
|
|
Another type of dating isssss
|
Chronometric which provides estimates in ~~~~actual~~~~ NUMBERS OF YEARS
|

|
Principal of superposition (DO YOU BELIEVE IN MAGICCCC!!???) :D
|
|
|
Analysis of sediment layers issss
|
Stratigraphy
|
|
|
Fluorine analysis is whattt
