Paleontology or palaeontology is the study of prehistoriclife forms on Earth through the examination of plant and animal fossils.[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have 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 or were published in the year 1990.
A mekosuchine crocodilian. Originally material from the Riversleigh WHA was also assigned to this species, but later research found these fossils to have belonged to a distinct taxon.

All Anatosaurus species except A. copei were moved to the previously existing genus Edmontosaurus by Brett-Surman
