Termes de paléontologie, anatomie et stratigraphie utilisés sur Dinopedia.
Cambrian explosion
Explosion cambrienne
Rapid biological diversification event that occurred approximately 541 million years ago at the start of the Cambrian period, during which most major animal body plans (phyla) appeared for the first time in the fossil record.
stratigraphie
Fossil
Fossile
Remains or trace of an organism that lived in the geological past, preserved in sedimentary rocks. Fossils can include bones, teeth, shells, impressions, or activity traces (ichnofossils).
taphonomie
Gigantothermy
Gigantothermie
Thermoregulation strategy in which an animal maintains a stable body temperature through sheer body mass, without true endothermy. Often proposed to explain the physiology of large dinosaurs.
physiologie
Graptolite
Graptolite
Extinct colonial marine organism from the Paleozoic, whose colonies formed thread-like or branching structures fossilized as writing-like markings on rocks (from Greek graphein, to write).
taxonomie
Mineralization
Minéralisation
Process by which organic tissues are progressively replaced by minerals (silica, calcite, pyrite?) during fossilization, preserving the original structure.
taphonomie
Paleobiology
Paléobiologie
Scientific discipline studying the biology of past organisms from their fossils: behavior, ecology, physiology, evolution, and population dynamics.
paléoécologie
Paleobotany
Paléobotanique
Branch of paleontology devoted to the study of fossil plants and the evolution of the plant kingdom through geological time.
taxonomie
Taphonomy
Taphonomie
Branch of paleontology studying the processes by which organisms become fossils: death, decomposition, transport, burial, diagenesis, and exposure. The term comes from Greek taphos (grave) and nomos (law).
taphonomie
Thagomizer
Thagomizer
Popular term for the cluster of bony spikes at the end of a stegosaur's tail, likely used as a defensive weapon. The name was coined in 1982 by cartoonist Gary Larson in his Far Side comic strip and subsequently adopted by paleontologists.
anatomie
Trilobite
Trilobite
Extinct marine arthropod that thrived from the Cambrian to the end of the Permian (541?252 Ma). Their body is divided into three longitudinal lobes and three regions: cephalon, thorax, and pygidium. They are excellent stratigraphic index fossils.
