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 or were published in the year 1957.

Literature

• Plutonia: An Adventure Through Prehistory by Russian geologist Vladimir Obruchev was published. The novel depicts a team of scientists, who find an arctic entry to a subterranean realm populated by dinosaurs. Other forms of prehistoric life and giant tortoises also made an appearance in Obruchev's underworld. Paleontologist William A. S. Sarjeant describes this novel's ending as "blea[k]" because after returning to the surface all of the scientists become involved in World War I and "all their trophies and even their lives are lost." The novel's portrayal of sauropods as being able to move about effectively on land was notable because at the time most scientists believed that sauropods relied on buoyancy in water to help support their body weight.^[8]
