Paleontology or palaeontology is the study of prehistoric life 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 1992.

Archosauromorphs
- During the 1992 field season a concerted effort was undertaken by the Royal Tyrell Museum to recover the remains of young hadrosaurs.[14] The researchers describe the acquisition that season of 43 specimens as being a success.[14] Most of the recovered fossils were of dentaries missing their teeth, bones from limbs and feet, as well as vertebral centra.[14]
- Jack Horner speculated that transitional species evolved in the uppermost part of the Two Medicine Formation during the Bearpaw Transgression. This was during a half-million year span as the transgression inundated the Judith River Formation and, later, the Two Medicine area, gradually destroying the local dinosaurs' preferred habitats.[15] Horner cited certain ceratopsid and pachycephalosaurid species as possible evidence for his hypothesis.[15]
