Expeditions, field work, and fossil discoveries

• Charles Gilmore returned to prospect for fossils in the Two Medicine Formation.^[6]

Institutions and organizations

• The Calgary Public Museum of Alberta, Canada closed due to financial problems triggered by the Great Depression. By this point the museum had accumulated roughly 7500 different items of both natural and man-made origin. The collections were stored in another Calgary building called the Coste House.^[7]
