Fossil Record Flash cards
uniformitarianism
the theory that changes in the earth’s crust during geological history have resulted from the action of continuous and uniform processes.
catastrophism
In geology, catastrophism theorises that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope.
paleontology
Paleontology, also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch.
relative dating
Relative dating is the science of determining the relative order of past events, without necessarily determining their absolute age.
absolute dating
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.
superposition
Quantum superposition is a fundamental principle of quantum mechanics.
isotope
Isotopes are two or more types of atoms that have the same atomic number and position in the periodic table,
radioactive decay
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration

A trace fossil, also ichnofossil, is a fossil record of biological activity but not the preserved remains of the plant or animal itself.
mold
A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae
cast
The mineralized impression of the organism left in the sediment is called a mold.
unconformity
An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages
mass extinction
An extinction event is a widespread and rapid decrease in the biodiversity on Earth.
Jurassic period
The Jurassic is a geologic period and stratigraphic system that spanned from the end of the Triassic Period 201.3 million years ago to the beginning of the Cretaceous Period,
Cretaceous period
Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era.
Devonian period
The Devonian is a geologic period and system of the Paleozoic, spanning 60.3 million years from the end of the Silurian, 419.2 million years ago,
Quaternary period
The Quaternary is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy.
Permian period
The Permian is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago,
