Water can come from roofs leaking during rainstorms, floods, fire sprinkler systems, or broken pipes. [7] It can soften and destroy the bone, antler, or horn if it becomes waterlogged. Mold and mildew growth can cause further damage. If the water in the crevices or pores of the bone, antler, or horn were to freeze, it would crack the object.
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 ...
Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
Bone is a material prone to cracks and splits during the dehydration process. If the bone has been established as weak and unstable, and that dehydration can cause cracks and splits to the bone structure, the bone is impregnated prior drying with the use of 50% solution of polyvinyl acetate (PVA(C 4 H 6 O 2) n) in distilled water.

Over 68 published and peer-reviewed studies have been conducted since 2002, out of these studies 15 found direct links to groundwater pollution from animals' waste at CAFOs. [5] Twelve of the studies made indirect links to water pollution and human health while seven found no link at all [6]
Nonpoint sources are the most significant single source of water pollution in the United States, accounting for almost half of all water pollution, [1] and agricultural runoff is the single largest source of nonpoint source water pollution. [2] This water pollution has a number of detrimental effects on human health and the environment.
Tests of animal bones found nearby suggest that the climate was harsh — comparable to modern-day Siberia. That means humans were having success in an extreme climate some 45,000 years ago.
Skeletonization is the state of a dead organism after undergoing decomposition. [1] Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed.
