geologic time scale = is a system of chronological measurement that relates
stratigraphy to time, and is used to describe the timing and relationships
between events that have occurred throughout Earth’s history.
Radiometric testing = a method of dating geological or archeological
specimens by determining the relative proportions of particular radioactive
isotopes present in a sample.
stratigraphy = The study of rock layers (strata), especially the distribution,
deposition, and age of sedimentary rocks.
era = a long and distinct period of history with a particular feature or
characteristic; several hundred million years
period = subdivision of an era
epoch = subdivision of a period
trilobite = extinct marine arthropod that occurred abundantly during the
Paleozoic era, with a carapace over the forepart, and a segmented hind part
divided longitudinally into three lobes.
fossil = the remains or impression of a prehistoric organism preserved in
petrified form or as a mold or cast in rock.
exoskeleton = external skeleton
endoskeleton = internal skeleton
plate tectonics = a theory explaining the structure of the earth's crust and
many associated phenomena resulting from lithospheric plates that move
over the underlying mantle.
cyanobacteria = blue-green algae a group of photosynthetic bacteria which
release oxygen into the atmosphere
amphibians = a cold-blooded vertebrate animal that has an aquatic gillbreathing larval stage followed by a terrestrial lung-breathing adult stage.
Egg layers in water.
reptiles = a cold-blooded vertebrate of a class that includes snakes, lizards,
crocodiles, turtles, and tortoises. They are distinguished by having a dry scaly
skin, and typically laying soft-shelled eggs on land.
extinction = the state or process of a species becoming extinct, no longer
existing on the Earth.
Pangea = a continent which included all the landmass of the earth prior to
the Triassic period
gymnosperm = a plant, such as a pinetree, whose seeds are not enclosed
within an ovary, fruit.
angiosperms = a plant having its seeds enclosed in an ovary; a flowering
plant.
mammal = a warm-blooded vertebrate animal of a class that is distinguished
by the possession of hair or fur, the secretion of milk by females for the
nourishment of the young, and the birth of live young.
marsupial = a mammal of an order whose members are born incompletely
developed and are typically carried and suckled in a pouch on the mother's
belly.
