1922 in paleontology

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 1922.

• Krausel reported fossil gut contents from an Edmontosaurus annectens mummy. He described the material as including conifer needles and branches, deciduous foliage, and possible small seeds or fruit. ^[6]
• Abel argued that the plant material Krausel argues was the fossilized remains of the gut contents of an Edmontosaurus annectens was actually deposited by flowing water. ^[6]
