Faunal Assemblage
In archaeology and paleontology a faunal assemblage is a group of animal fossils found together in a given stratum. In a non-deformed deposition, fossils are organized by stratum following the laws of uniformitarianism and superposition, which state that the natural phenomena observable today (such as death, decay, or post-mortem transport) also apply to the paleontological record and that the oldest stratum will be at the bottom of a paleontological deposit. The principle of faunal succession is used in biostratigraphy to determine each biostratigraphic unit, or biozone. The biostratigraphic unit is a section of geological strata that is defined on the basis of its characteristic fossil taxa or faunal assemblage. Faunal assemblages are also analyzed in archaeological deposits, where they are influenced by cultural activities in addition to ecological processes and natural taphonomy. Taphonomy Taphonomy is translated from Greek as "laws of burial" (''taphos + nomos''). From dea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeology
Archaeology or archeology is the 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. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. 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. A ...

Biostratigraphy
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them.Hine, Robert. "Biostratigraphy." ''Oxford Reference: Dictionary of Biology'', 8th ed., Oxford University Press, 2019. The primary objective of biostratigraphy is ''correlation'', demonstrating that a particular horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to help identify biozones, as they make up the basic biostratigraphy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleozoology
Palaeozoology or paleozoology ( Greek: παλαιόν, ''palaeon'' "old" and ζῷον, ''zoon'' "animal") is the branch of paleontology and evolutionary biology that specifically deal with the study of prehistoric organisms from the kingdom Animalia and the recovery and identification of their fossil remains from geological (or even archeological) contexts. The field also extends to the use of these fossil records for reconstructive phylogeny (via comparative anatomy and phylogenetics) and paleoecology, i.e. the study of ancient natural environments and ecosystems. While speculative fossils of earliest animals (in the form of primitive sponges such as ''Otavia'') can trace back to the late Tonian period of the mid-Neoproterozoic era, definitive macroscopic metazoan remains are mainly found in the fossil record from the Ediacaran period onwards, although they do not become common until after the Cambrian Explosion, and vertebrate fossils do not become common until the L ...

Zooarchaeology
Zooarchaeology or archaeozoology merges the disciplines of zoology and archaeology, focusing on the analysis of animal remains within archaeological sites. This field, managed by specialists known as zooarchaeologists or faunal analysts, examines remnants such as bones, shells, hair, chitin, scales, hides, and proteins, such as DNA, to derive insights into historical human-animal interactions and environmental conditions. While bones and shells tend to be relatively more preserved in archaeological contexts, the survival of faunal remains is generally infrequent. The degradation or fragmentation of faunal remains presents challenges in the accurate analysis and interpretation of data. Characterized by its interdisciplinary nature, zooarchaeology bridges the studies of ancient human societies and the animal kingdom. Practitioners, from various scientific backgrounds including anthropology, paleontology, and ecology, aim primarily to identify and understand human interactions with a ...

Tanis (fossil Site)
Tanis is a private paleontological site in southwestern North Dakota, United States. It is part of the heavily studied Hell Creek Formation, a geological region renowned for many significant fossil discoveries from the Upper Cretaceous and lower Paleocene. Based solely on the Tanis team's publications, the Tanis is unique in that it allegedly records, in detail, concrete evidence of the direct effects of the giant Chicxulub impactor, Chicxulub asteroid impact which struck the Gulf of Mexico 66.043 million years ago, and wiped out all non-avian dinosaurs and many other species (the so-called Cretaceous–Paleogene extinction event, "K–Pg" or "K–T" extinction). The extinction event caused by this impact began the Cenozoic, in which mammals—including humans—eventually came to dominate life on Earth. Discoveries The site was originally discovered in 2008 by University of North Georgia Professor Steve Nicklas and field paleontologist Rob Sula. Their team successfully removed ...

La Brea Tar Pits
La Brea Tar Pits comprise an active Paleontological site, paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural Bitumen, asphalt (also called asphaltum, bitumen, or pitch; ''brea'' in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have been preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. "La Brea Tar Pits" is a registered National Natural Landmark. Formation Tar pits are composed of Heavy crude oil, heavy oil fractions, called gilsonite, which seep from the earth as oil. Crude oil seeps up along the 6th Street Fault from the Salt Lake Oil Field, which underlies much of the Fairfax District north of Hancock Park. The oil reaches the surface and forms pools, becoming asphalt as the lighter fractions of the petroleum biodegrade or evaporate. The asphalt the ...

Lagerstätte
A Fossil-Lagerstätte (, from ''Lager'' 'storage, lair' '' Stätte'' 'place'; plural ''Lagerstätten'') is a sedimentary deposit that preserves an exceptionally high amount of palaeontological information. ''Konzentrat-Lagerstätten'' preserve a high concentration of fossils, while ''Konservat-Lagerstätten'' offer exceptional fossil preservation, sometimes including preserved soft tissues. ''Konservat-Lagerstätten'' may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying the decomposition of both gross and fine biological features until long after a durable impression was created in the surrounding matrix. ''Fossil-Lagerstätten'' spans geological time from the Neoproterozoic era to the present. Worldwide, some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale, the Ordovician Soom Shale, the Silurian Waukesha Biota, the Devonian Hunsrück Slates and Gogo Formation, the Ca ...

Lang Rongrien
Lang Rongrien () is a rock shelter and Hoabinhian habitation site in the upland region of Krabi province in west-coast southern Thailand. The site is of the Pleistocene, early Holocene archaeological time frame. Excavations at the site began in 1974, and primary research was headed by Douglas Anderson. Though this rock shelter site is not as large as some others, it is archaeologically rich in its findings. Some of the sediment at the site was disturbed by soil collections, but not enough to have ruined the more impressive archaeological finds. The site is located within the Krabi River valley, in a somewhat hard-to-reach area that can only be accessed from a steep trail below the rock shelter, or a narrow ridge that approaches the rock shelter from the north. Radiocarbon dating at the site has put the evidence from between 39,000 and 28,000 years before present. Habitation Hoabinhian habitation sites are most often found in rock shelters, and are found all across southeas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephantoidea
Elephantimorpha is a clade of proboscideans that contains the Mammutidae (mastodons), as well as Elephantida ( amebelodonts, choerolophodonts, gomphotheres, stegodontids and elephantids). All members of Elephantimorpha have the horizontal tooth replacement typical of modern elephants, where the cheek teeth progressively migrate forwards in the jaw like a conveyor belt. This a distinctive characteristic of this group (synapomorphy) and is not found in more primitive non-elephantimorph Elephantiformes. Members of Elephantida are distinguished from mammutids by the reduced angular process of the lower jaw. Like modern elephants, the ancestor of Elephantimorpha was likely capable of communicating via infrasonic calls. While early elephantimorphs generally had lower jaws where the fused front part (the mandibular symphysis) was greatly elongated with well developed lower tusks/incisors, from the Late Miocene onwards, many groups convergently developed brevirostrine (shortened) lower j ...

Suidae
Suidae is a family (biology), family of Even-toed ungulate, artiodactyl mammals which are commonly called pigs, hogs, or swine. In addition to numerous fossil species, 18 Extant taxon, extant species are currently recognized (or 19 counting domestic pigs and wild boars separately), classified into between four and eight genera. Within this family, the genus ''Sus'' includes the domestic pig, ''Sus scrofa domesticus'' or ''Sus domesticus'', and many species of wild pig from Europe to the Pacific. Other genera include babirusas and warthogs. All suids, or swine, are native to the Old World, ranging from Asia to Europe and Africa. The earliest fossil suids date from the Oligocene epoch in Asia, and their descendants reached Europe during the Miocene. Several fossil species are known and show adaptations to a wide range of different diets, from strict herbivory to possible carrion-eating (in Tetraconodontinae). Physical characteristics Suids belong to the order (biology), order Artio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
