Most medium-sized animals (like dogs) are macerated within about ten days. Lipids and fatty acids in the bone and in the fat tissues tend to stain the bone brown. Oxidising bleaches may be used to whiten the bone, but if too much is used the perchlorate or hypochlorite damages the bone tissue, leaving it chalky and brittle. Hydrogen peroxide at ...
Bone is also made of both mineral and carbon-based materials; the mineral-based are calcium, phosphorus, and fluoride; the carbon-based is the protein ossein. Bone also includes the mineral hydroxyapatite, "A calcium phosphate mineral which forms a hard outer covering over the collagen and protein matrix," [1] or organic material.
Bone char (Latin: carbo animalis) is a porous, black, granular material produced by charring animal bones. Its composition varies depending on how it is made; however, it consists mainly of tricalcium phosphate (or hydroxyapatite) 57–80%, calcium carbonate 6–10% and carbon 7–10%. [1] It is primarily used for filtration and decolorisation.
Treatments should be carried out by conservators or qualified taxidermists. Some taxidermists have experience working with museums and can coordinate with conservators to preserve specimens. When cleaning specimens, it is necessary to wear protective gear such as nitrile gloves, dust masks, eye protection, and lab coats.
Zooarcheologists can find out information like the species the animal is, the age the animal was when it died, and what its sex was. [ 11 ] Some common faunal remains found at sites include, as stated above, bones, shells, hair, chitin, scales, hides, proteins and DNA.
Pastor Bob Wood (1993): The first night, of course, you know, I was up on the road all night — out in the woods all night. The second day I was on the road all night, watching.
Methods used to prepare the animal remains included removing all flesh from the bone by scraping, boiling and air drying the scapula by hanging up in the wind to dry. [3] The animal from which the bone was from was also ritually significant. [3] Caribou were preferred by the Innu people, as they were the main and most desirable species to be ...
