Abstract

There are skeletal collections in museums and universities throughout the world that are not useful to the zooarchaeologist because they have not been properly cleaned–often the result of having been processed in the field. In this paper, a method to clean the bones of smaller animals is presented that is both quick and efficient with a minimum of special requirements. This method was designed to work under field conditions to create reference collections of local fauna. Three objectives were considered: a) preparing high quality skeletal material, b) minimizing the amount of specialized equipment needed to do so, and c) having a process easy to perform under non-laboratory conditions. The method developed involves maceration by the use of the enzyme proteinase trypsin. This form of maceration is easy to use and has given excellent results both in the laboratory and in the field. It has been used to prepare skeletons of small mammals, birds, reptiles, amphibians, and especially fish.Existen colecciones esqueléticas en museos y universidades por todo el mundo que no resultan de utilidad al zooarqueólogo debido a que no han sido adecuadamente preparadas. Ello es resultado de que los restos hayan sido frecuentemente procesados sobre el terreno. En este trabajo presentamos un método para preparar los huesos de los animales de menor tamaño que es rápido y eficiente y con un mínimo de requisitos específicos. El método fue diseñado para crear sobre el terreno colecciones de referencia de la fauna local. Tres objetivos fueron considerados: a) preparación de un material esquelético de alta calidad, b) minimizar los requisitos de instrumental especializado requerido para llevar esto a cabo y c) disponer de un procedimiento fácil fuera del laboratorio. El método nuevo desarrollado implica la maceración con el uso de la enzima tripsina. Este tipo de maceración es de muy fácil uso y ha proporcionado excelentes resultados tanto en el laboratorio como en el campo. Se ha utilizado para preparar esqueletos de micromamíferos, aves, reptiles, anfibios y muy especialmente peces.
