Mrs. Corey's Paleontology Unit

TermDefinition
Uniformitarianism Principle that states that geologic processes that occurred in the past can be explained by current geologic processes; change occurs slowly
Superposition Younger rocks lie above older rocks if the layers have not been disturbed
Original horizontality Most sedimentary layers of rock are deposited in a horizontal position
Trace fossil most commonly preserved in sedimentary rock, but also found in amber, ice, asphalt, or formed through petrifaction; index fossils help scientists determine the relative of ages of other fossils and rock layers; examples are footprints or fossilized dung
Catastrophism Geologic change that occurs suddenly
Relative Dating Method of determining whether an event or object is older or younger than other events or objects
Fossil record The fossils found on Earth and the information provided by those fossils about Earth’s past
Unconformity Missing rock layers caused by erosion or some other disturbance
Absolute Dating Method of measuring the age of an event or object in actual years
Geologic column Arrangement of rock layers with the oldest rocks at the bottom
Geologic time scale Method used to divides Earth’s long natural history into parts (i.e. eons, eras)
Paleontology Scientific study of fossils
Eon the largest division of geologic time
Era units of geologic time that include periods (Paleozoic, Mesozoic, Cenozoic)
Period units of time into which eras are divided (Jurassic, Cretaceous, etc.)
