Preserved body parts
Casts/molds (external shape)
Imprints (footprints, tunnels)
Amber (insects trapped in sap)

Term
| Formation of Fossils requires |
|
Definition
~rapid burial of organisms
~rapid deposition of sediments
~rapid burial is required because organisms must escape destruction and decomposition |
|
|
Term
| Formation of Sedimentary Rocks |
|
Definition
~erosion and deposition in layers
~lithification; sediment changed into rock |
|
|
Term
| Fossil record predictions (evolution) |
|
Definition
~Gradual sequence from simple to complex organisms
~Transitional forms should be abundant
~Living spiecies significantly different than fossil ancestors
~Modern speicies should not be found in rocks, older than rocks containing supposed ancestors |
|
|
Term
| Fossil record predictions(creations) |
|
Definition
~sudden appearance of complex organisms with few transitional forms
~organisms remain essentially the same to present or become extinct
~fossilized modern species could be found in rock containing extinct species
~different combinations of fossil species in different strata indicate ecological zones, not evolutionary history |

Term
| History of Evolutionary Thought Regarding Geology |
|
Definition
~Until mid to late 1700s common belief was that sedimentary rocks/fossils were all deposited in Noah's Flood
Catastrophism-rapid, violent, major events could radically shape the planet very quickly
~Uniformitarianism- The present is the key to the past
Unbiblical views were challenged by scriptural geologists |
|
|
Term
|
Definition
~Cuvier and others believed a series of catastrophes was supposedly responsible for geologic formations
~He thought God supernaturally repopulated the earth after each catastrophe
~Did not take a straightforward approach to Scripture |
|
|
Term
|
Definition
~Only processes observed today can be used to describe past events
~Proposed by James Hutton, popularized by Charles Lyell
~First theory to suggest that the earth was very old.
~Viewed earth and universe as continuously changing with no beginning and no end |

Definition
~Group who objected to old earth compromises
Some Christians had compromised (Gap or day age)
~Theological objections
Old earth geologists ignored Genesis 6-9(Noah's flood)
An old earth postulates long ages of violence and death
~Geological objections
Deposition of sediments was rapid
Polystrate fossils
Some fossil human remains were found with extinct animals of a supposed earlier geologic age
Geology was really in its infancy |

Term

Definition
some fossils exist through more than one strata
Ex: Fossilized or pretrified trees which cross strata |

William Smith: Principle of Biologic Succession
- Fossils increase in complexity with time and fossils could be used to identify (data) strata around the globe |

| Theory of Natural selection (origin of species through time) |
|
|
Term
|
Definition
Different types of organism are found in different types of strata
Increasing complexity occurs more recently in geologic time (not really) |

~Creation model: Sudden appearance and fully formed
~Evolution model: Gradual progression from simple to complex |
|
|
Term
| Gradual or Sudden Appearance? |
|
Definition
~"Oldest" rocks containing abundant fossils are from the cambrian period
~The Cambrian Explosion is "Evolution's Big Bang"
~Sudden appearance of a wide variety of living things with no apparent ancestors
~Time Magazine: "New discoveries show that life as we know it began in an amazing biological frenzy that changed the planet almost overnight." |
