Lehner Mammoth-Kill Site
The Lehner Mammoth-Kill Site is a location in southern Arizona that is significant for its association with evidence that mammoths were killed here by Paleo-Indians 9000 years BCE. In 1952, Ed Lehner discovered extinct mammoth bone fragments on his ranch, at the locality now known as the Lehner Mammoth-Kill Site. He notified the Arizona State Museum, and a summer of heavy rains in 1955 exposed more bones. Excavations took place in 1955–56, and again in 1974–75. In the first season, two Clovis projectile points were found among the ribs of a young mammoth. Artifacts found during these excavations included thirteen fluted Clovis culture projectile points, butchering tools, chipped stone debris and fire hearth features. Bones of a variety of game—twelve immature mammoths, one horse, one tapir, several bison, one camel, one bear, several rabbits, and a garter snake—were excavated at the Lehner site. The Lehner Mammoth kill and camp site exhibited a number of firsts: It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naco Mammoth Kill Site
The Naco Mammoth Kill Site is an archaeological site in southeast Arizona, 1 mile northwest of Naco in Cochise County. The site was reported to the Arizona State Museum in September 1951 by Marc Navarrete, a local resident, after his father found two Clovis points in Greenbush Draw (eroded by the Greenbush Creek, a tributary of the San Pedro river), while digging out the fossil bones of a mammoth. Emil Haury excavated the Naco mammoth site in April 1952. In only five days, Haury recovered the remains of a Columbian Mammoth in association with 8 Clovis points (including the 2 originally found by the Navarettes). The excavator believed the assemblage to date from about 10,000 Before Present Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s.

Paleontology In Arizona
Paleontology in Arizona refers to paleontological research occurring within or conducted by people from the U.S. state of Arizona. The fossil record of Arizona dates to the Precambrian. During the Precambrian, Arizona was home to a shallow sea which was home to jellyfish and stromatolite-forming bacteria. This sea was still in place during the Cambrian period of the Paleozoic era and was home to brachiopods and trilobites, but it withdrew during the Ordovician and Silurian. The sea returned during the Devonian and was home to brachiopods, corals, and fishes. Sea levels began to rise and fall during the Carboniferous, leaving most of the state a richly vegetated coastal plain during the low spells. During the Permian, Arizona was richly vegetated but was submerged by seawater late in the period. During the Triassic, Arizona was home to a rich forest home to dinosaurs and early relatives of mammals. Jurassic Arizona had a drier climate and was covered by sand dunes where dinosaurs le ...

Protected Areas Of Cochise County, Arizona
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Archaeological Sites On The National Register Of Historic Places In Arizona
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes ove ...

Pre-Columbian Archaeological Sites
In the history of the Americas, the pre-Columbian era spans from the original settlement of North and South America in the Upper Paleolithic period through European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures. Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European colonies (c. late 16th–early 17th centuries), and are known only through archaeological investigations and oral history. Other civilizations were contemporary with the colonial period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own wri ...

Cenozoic Paleontological Sites Of North America
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
