[ES] En este trabajo se hace una primera aproximación para relacionar la histología conservada en huesos fósiles de mamíferos con la edad biológica del individuo. Existe una relación entre el desarrollo del hueso y el estadio de crecimiento para la generalidad de los mamíferos. Comparando con los ejemplos histológicos pertenecientes a mamíferos actuales y con estudios médicos sobre humanos actuales y fósiles, se han podido comprobar en los fósiles de Somosaguas y Layna características como forma, tamaño, tipo de matriz, densidad de osteonas y osteocitos, que nos permitirán en un futuro desarrollar un método preciso para asignar una edad relativa a un resto óseo sin necesidad de tener el resto completo, simplemente con la sección de un fragmento de diáfisis.
[EN] This is a first approach to relate conservated fossil bone histology and growth stages for fossil mammals. A relationship exists between bone development and individual age for mammal bones. Comparing histological models belonging to actual mammals and human bones, it has been verified in fossil bones from Somosaguas and Layna sites some characters such as shape, size and density of osteones and osteocites, kind of matrix, etc., that will allow us to develop a method to assign relative age to a fragment of fossil bone.
