Captain Marshall Field Expeditions
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.

Field Museum Of Natural History
The Field Museum of Natural History (FMNH), also known as The Field Museum, is a natural history museum in Chicago, Illinois, and is one of the largest such museums in the world. The museum is popular for the size and quality of its educational and scientific programs, and its extensive scientific-specimen and artifact collections. The permanent exhibitions, which attract up to two million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation needs. The museum is named in honor of its first major benefactor, Marshall Field, the department-store magnate. The museum and its collections originated from the 1893 World's Columbian Exposition and the artifacts displayed at the fair. The museum maintains a temporary exhibition program of traveling shows as well as in-house produced topical exhibitions. The professional staff maintains collections of over 24 million specimens and objects tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Statham Williams
Robert Statham Williams (May 6, 1859 – March 14, 1945) was an American bryologist who specialized in the mosses of the Yukon and South America. Early life Williams was born in Minneapolis, Minnesota on May 6, 1859. Since childhood, he had always been interested in natural history, particularly in birds and plants. As a teen, he published a series of nature columns in a Minneapolis newspaper. Williams, captivated by ornithology, prepared an almost complete set of taxidermied skins of birds from Minnesota. He sold his collection to the Minnesota Museum of Natural History to fund his later explorations, a decision which he regretted later in life. Career In 1879, at the age of 20, Williams moved from his hometown of Minneapolis, Minnesota to Montana. Here, he made a living working as a miner, businessman, and explorer.

Nazca
Nazca (; sometimes spelled Nasca; qu, Naska) is a city and system of valleys on the southern coast of Peru. It is also the name of the largest existing town in the Nazca Province. The name is derived from the Nazca culture, which flourished in the area between 100 BC and AD 800. This culture was responsible for the Nazca Lines and the ceremonial city of Cahuachi. They also constructed additional underground aqueducts, named puquios, in a regional system that still functions today. The first puquios are believed to have been built by the preceding Paracas culture. Nazca is the capital of the Nazca Province located in the Ica District of the Ica region of Peru. Earthquake On November 12, 1996, at 11:59 a.m. local time (16:59 GMT) there was an earthquake of magnitude 7.5 with its epicenter at 7.7 km into the sea.

Andalgalornis Ferox
''Andalgalornis'' is a genus of flightless predatory birds of the extinct family Phorusrhacidae (often called "terror birds") that lived in Argentina. The type and only species is ''A. steulleti''. Taxonomy ''Andalgalornis'' is known from an incomplete skeleton and some single bones found from sites in the Entre Ríos and Catamarca Provinces of northeast and northwest Argentina. The fossils were uncovered from the Late Miocene (Huayquerian in the SALMA classification) Ituzaingó Formation of the Paraná Basin. at .org The following |
Thylacosmilus Atrox
''Thylacosmilus'' is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs. Though ''Thylacosmilus'' looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American ''Smilodon'', but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to convergent evolution. A 2005 study found that the bite forces of ''Thylacosmilus'' and ''Smilodon'' were low, which indicates the killing-techniques of saber-toothed animals differed from those of extant species. Remains of ''Thylacosmilus'' have been found primarily in Catamarca Province, Catamarca, Entre Ríos Province, Entre Ríos, and La Pampa Provinces in northern Argentina. Taxonomy In 1926, the Marshall Field Paleontological Expeditions collected mammal fossils from the Ituzaingó Formation of Corral Quemado, Catamarca, Corral Quemado, in Catamarca Province, northern ...
