Paleontology or palaeontology (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 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 1913.

Expeditions, field work, and fossil discoveries

• April: William Edmund Cutler prospected in Dinosaur Provincial Park. His work was underwritten by the Calgary Syndicate for Prehistoric Research, a group of local philanthropist businessmen, and a small local museum, the Calgary Public Museum, which no long exists.^[2]
• Summer: The American Museum of Natural History dispatched a team of fossil hunters to Dinosaur Provincial Park. Cutler joined the expedition but was "asked to leave" after only a few months of involvement.^[2]
• Cutler excavated a juvenile Grypsaurus now catalogued by the Canadian Museum of Nature as CMN 8784. The site of the excavation has since been designated "quarry 252".^[2]
• Winter: Cutler partly prepared the young Gryposaurus specimen, possibly in Calgary while working on dinosaurs for Euston Sisely.^[2]
• A US Geological Survey crew headed by Eugene Stebinger and a US National Museum crew headed by Charles Gilmore worked together to excavate the first dinosaur discovery of the Two Medicine Formation.^[3]
