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.[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (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 1933.

Dinosaurs[edit]

  • Barnum Brown prospected the Two Medicine Formation, but found nothing significant.[2]
  • Lull published a mongraph wherein he discusses AMNH 5244, a ceratopsian braincase.[3]
