Paleontologyor palaeontology is the study ofprehistoric life formsonEarththrough the examination of plant and animalfossils.^[1]This includes the study of body fossils,tracks(ichnites),burrows,cast-off parts, fossilisedfeces(coprolites),palynomorphsandchemical residues.Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as ascience.This article records significant discoveries and events related to paleontology that occurred or were published in the year 2001.
