Paleontology, palaeontology or palæontology (from Greek: ''paleo'', "ancient"; ''ontos'', "being"; and ''logos'', "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised faeces (coprolites), palynomorphs and chemical residues. Because mankind has encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred in the year 1978. ==Expeditions, field work, and fossil discoveries==
* A paleoanthropological team led by Mary Leakey found 3.5 million year old human footprints. * Baby hadrosaurs were discovered in the Two Medicine Formation.〔
