The Captain Marshall Field Expeditions for Vertebrate Paleontology
The Field Museum Library has shared a collection of photographs from the institution's expeditions to South America in the 1920's. The expeditions were undertaken with the goal of finding Cenozoic mammals and comparing them to their northern hemisphere counterparts, but at least a couple dinosaurs popped up, as well. Not just any dinosaurs. Huge dinosaurs. Enormous Argentinian sauropods like Antarctosaurus and Argyrosaurus, which to this day aren't well-understood or studied.

Some mammals turned up as well, of course, including Megatherium, Scelidodon, and Panochthus.

The bulk of the collection, however, is made up of photos taken during the groups' travels, capturing snapshots of life in Argentina in the '20s. See more.
