represents
graphically the chronological order of events

that helps us understand

the duration of an event

extinction of dinosaurs

the historian

having collected the information puts it in

chronological order

that is

in time order

therefore

what is closer to us

what happened before

different measures can be used:

ERAS
very long geological periods

MILLIONS OF YEARS

prehistory and appearance of species

THOUSANDS / HUNDREDS OF YEARS

ancient, medieval and modern history
