Osteotécnica Decomposição de carcaças na obtenção de peças esqueléticas e comparação de tempo na degradação dos ossos

Abstract

Since ancient times, techniques for collecting and preparing biological materials have been developed to provide better handling and practical study, and can thus be used in taxonomic comparisons and the preservation of the material of already extinct species stored in zoological collections. The skeletal system, a rigid calcified structure, is responsible for the storage of minerals, locomotion, protection, support and production of blood cells. The cadaveric decomposition, used in one of the many methodologies used to acquire skeletal parts, occurs through rapid and diverse biological, physical and chemical changes, with the degradation of the soft tissues of the body by autolysis, carnivorous insects and bacterial activity.
