Study Notes
Fossils
- Fossils are considered an exciting world, a story within sedimentary rocks. They reveal the deep past, millions of years before human existence.
- Fossils are traces and remnants of ancient living organisms preserved in sedimentary rocks.
- Traces are marks of an organism's activity during life.
- Examples of traces include worm tunnels and dinosaur footprints.
- Remains are the parts of an organism after death.
- Examples of remains include shark teeth and dinosaur skulls.
Types of Fossils
- Fossils are classified by how they formed (preserved).
- Fossil of a complete body: Preserves the complete shape and detail of a deceased organism rapidly buried (e.g., snow, amber).
- Mammoths preserved in snow are an example.
- Amber, solidified tree resin, preserved insects.
- Mold fossils: Form when an organism's hard parts are buried, the organism decays and a hollow impression is left in the surrounding rock.
- A mold is a replica of the internal details.
- Cast fossils: Form when minerals fill the hollow mold created by the decaying organism.
- An external replica of the organism.
- Petrified fossils: Minerals replace the organic material of an organism, preserving its shape.
- Petrified wood is an example. This occurs in slowly changing conditions.
Fossil Formation
- Minerals replace the organic matter of an organism.
- The organism is buried quickly and is preserved from decomposition or decaying.
- The appropriate environmental conditions are required for fossil formation.
Importance of Fossils
- Age determination of sedimentary rocks.
- Understanding paleoenvironments. This is figuring out the environment organisms lived in during the past e.g. climate.
- Studying life evolution.
- Petroleum exploration.
Fossil Record
- The order that fossils appear in sedimentary rock layers shows how organisms evolved.
- Life began in the sea and later developed on land.
- Organisms evolved from simple to complex forms.
Animal Fossils
- Invertebrates (e.g., corals, mollusks) came before vertebrates (e.g., fish).
- Fish preceded amphibians, then reptiles, and finally birds and mammals.
Index Fossils
- Organisms that lived briefly but were geographically widespread.
- Their presence in sedimentary layers indicates the approximate age of the layer.
