Knowra Paleobiology Paleobiology Paleobiology studies ancient life through fossils and geological evidence, reconstructing organisms, ecosystems, and evolutionary change across deep time.
Fossil : Preserved remains, traces, or chemical evidence of past organisms. Fossils are paleobiology’s primary direct evidence of ancient life.
Fossilization : The processes by which an organism or its traces become preserved in the geological record. Different preservation pathways determine what paleobiologists can observe.
Paleobotany : The study of fossil plants, including their evolution, ecology, and distribution. Plant fossils reveal the history of vegetation and terrestrial ecosystems.
Burgess Shale : A Cambrian fossil deposit in British Columbia renowned for exceptionally preserved soft-bodied animals. Its fossils preserve anatomical detail rarely found in ordinary deposits.
Taphonomy : The study of how organisms decay, become buried, and are preserved as fossils. It explains which parts of ancient organisms enter the fossil record.
Biostratigraphy : The dating and correlation of rock layers using their fossil content. Fossil distributions help place rocks in relative chronological order.
Paleozoology : The study of fossil animals and their evolutionary and ecological history. Animal fossils document body-plan evolution and past ecological roles.
Ediacaran biota : A diverse assemblage of mostly soft-bodied organisms that lived before the Cambrian period. These fossils bear on the early history of complex animal life.
Geologic time scale : A chronological framework dividing Earth’s history into eons, eras, periods, and epochs. It places fossil organisms and evolutionary events in time.
Stable isotope analysis : The measurement of stable isotope ratios to infer past biological and environmental conditions. Isotope signatures in fossils can reveal diet, climate, and habitat.
