The Captain Marshall Field Expeditions were undertaken by the Field Museum of Natural History in Chicago, Illinois. The two Captain Marshall Field paleontological expeditions had the goal of finding South American Cenozoic mammals. The mammals of South America had evolved in near total isolation from the rest of the world from almost the beginning of the Cenozoic Era until only a few million years ago.




Captain Marshall Field Brazilian Expedition


In addition to his regular annuity of $100,000, in 1927 Captain Marshall Field provided $40,000 to defray the expenses of the Brazilian Expedition under the leadership of Mr. George K. Cherrie. Mrs. Marshall Field III and Mrs. Ernest Thompson Seton were members of this expedition, and the following members of the Museum staff participated:

Dr. B. E. Dahlgren, Acting Curator of the Department of Botany, assisted by J. R. Millar and George Petersen
Professor Henry W. Nichols, Associate Curator of Geology
Assistant Curator Karl P. Schmidt and Assistant Colin C. Sanborn of the Department of Zoology
From the Captain Marshall Field Brazilian Expedition the Library of the Field Museum has received 144 works, which were immediately useful in identifying and classifying the material collected. Some of these publications could be obtained only by the personal efforts of members of the staff while in Brazil.




1st Captain Marshall Field Paleontological Expedition to Argentina and Bolivia



The 1st Captain Marshall Field Paleontological Expedition to Argentina and Bolivia was undertaken by Elmer S. Riggs. His field crew included George F. Sternberg, John B. Abbott, Jose Strucco and C. Harold Riggs. The expedition started 1922 and finished in 1925. The objective was to find new fossil mammals from Cenozoic deposits in Chubut Province and Santa Cruz Province of Argentina and the Tarija Valley of Bolivia. The expedition succeeded in securing over 900 fossil vertebrate specimens including 12 new species with 12 holotypes, 14 paratypes and over 50 specimens since figured in scientific publications. While prospecting in the Cenozoic, brief forays into Mesozoic deposits in the San Bernardo Hills of Catamarca Province in Argentina unearthed three leg bones of enormous sauropods identified as Antarctosaurus and Argyrosaurus.




2nd Captain Marshall Field Paleontological Expedition to Argentina and Bolivia



The 2nd Captain Marshall Field Paleontological Expedition to Argentina and Bolivia was undertaken in 1926, again under the leadership of Elmer S. Riggs. This time his field crew included Rudolf Stahlecker, Robert C. Thorne, Jose Strucco, Luis Flores, Felipe Mendez, and Colin Campbell. The expedition started in April 1926 and finished in November 1927. Riggs was again looking for Cenozoic fossil mammals and ended up working in Catamarca Province, and Buenos Aires Province, in Argentina and the Tarija Valley in Bolivia. He and his team discovered over 500 fossil vertebrates including seven new species such as the saber-toothed marsupial, Thylacosmilus atrox and flightless terror bird, Andalgalornis ferox.




Archaeological explorations in Peru and British Honduras


Archaeological explorations were conducted in Peru and British Honduras. These focussed on ancient pottery from Trujillo, textiles of the early Nazca period and an osteological study of Nasca trophy heads collected by A.L. Kroeber.




The Marshall Field North Arabian Desert Expeditions


The Marshall Field North Arabian Desert Expeditions of 1927-1928 secured twelve specimens of lizards and snakes in Transjordania and Iraq. This material, which proves to be an accession of unusual interest, was collected in 1928 by Mr. Henry Field, Assistant Curator of Physical Anthropology in Field Museum of Natural History.




The Marshall Field Botanical Expedition to the Amazon


The Peruvian division of this expedition, led by Field Museum staff member Llewelyn Williams, returned in May 1930 with 8,000 botanical specimens. The Brazilian division, led by Field Museum Acting Curator D. B. E. Dahlgren, returned several months earlier.
