The Deseado Formation of Patagonia

"The Deseado Formation of Patagonia" by Frederic Brewster Loomis is a scientific publication written in the early 20th century. The work focuses on the results of the Amherst Expedition to Patagonia, which took place in 1911, and is primarily concerned with the paleontological findings related to the Deseado Formation, featuring a comprehensive study of Tertiary vertebrate fauna. Loomis's analysis extends the existing knowledge of prehistoric animal life in Patagonia through extensive fossil collection and interpretation. The opening of the book introduces the Amherst Expedition, detailing its organization, participants, and objectives. Loomis illustrates the significance of the fossils collected from the Deseado Formation, emphasizing their importance in understanding the vertebrate animals of the Tertiary period. He references pioneering work done by previous researchers, particularly Carlos and Florentino Ameghino, and outlines the expedition's aim to create a detailed monograph on their findings. Initial chapters discuss the geological context, the descriptions of the material found, and comparisons with other paleontological collections, setting the groundwork for the comprehensive analysis of ancient fauna that Loomis presents throughout the volume.
