Artifact (archaeology)
An artifact or artefact (British English) is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance; it is defined as an object recovered by archaeological endeavor, including cultural artifacts (of archaeological culture, cultural interest). "Artifact" is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with Biofact (archaeology), ecofacts and Feature (archaeology), features; all three of these can sometimes be found together at archaeological sites. They can a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Skull
The skull, or cranium, is typically a bony enclosure around the brain of a vertebrate. In some fish, and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In the human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolved from the first pharyngeal arch. The skull forms the frontmost portion of the axial skeleton and is a product of cephalization and vesicular enlargement of the brain, with several special senses structures such as the eyes, ears, nose, tongue and, in fish, specialized tactile organs such as barbels near the mouth. The skull is composed of three types of bone: cranial bones, facial bones and ossicles, which is made up of a number of fused flat and irregular bones. The cranial bones are joined at firm fibrous junctions called sutures and contains many foramina, fossae, processes, and sinuses. In zoology, the openings in the skull are called fenestrae, the most ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Abanda Caves
The Abanda Caves are a cave complex in Gabon, located in the upstream of Fernan Vaz Lagoon. They were first mentioned by Dr. Marco Marti and Claude Werotte in the early 2000s, and fully explored during several caving expeditions by Oslisly, Olivier Testa, Testa, Sebag and Shirley. There are two independent cave networks: the Dinguembou cave (350m) and the Mugumbi cave (400m). Access to the horizontal passages is possible through vertical shafts of about 7m deep. They host large colonies of bats (Egyptian fruit bat, Sundevall's roundleaf bat, Giant roundleaf bat) estimated to more than 100,000 individuals. Picathartes nests have been observed at the entrances of the caves. The Caves of Abanda are known to host an endemic population of orange-colored cave-dwelling dwarf crocodiles. They were described by herpetologist Matthew H. Shirley after the first scientific expedition in the caves in 2010. These crocodiles live in complete darkness, they feed mostly on bats and cave crickets ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
