Resumen:
The economic anatomy for Rheidae (Class: Birds) which include the calculation of the Modified General Utility Index (MGUI) and its component indexes: Meat Utility Index (MUI), Marrow Index (MI), White Grease Index (WGI) and General Utility Index (GUI) are presented in this presentation. In addition, the methodology implemented for obtaining each index and the discussion of the results in an archaeofaunal setting are also presented. The results obtained show net values of meat utility, which are associated to the anatomical portions belonging to the appendicular skeleton, a high grease index, associated to the axial portions (mainly pelvic waist and sternum) and high marrow index in tibiotarsus and tarsometatarsus. The correlation that exists between the Economic Utility Index and the Structural Bone Density Index is analyzed, showing an equifinality problem. Finally, there is a comparison of the utility index for other ratites built with the purpose of giving an analogy for all the species that constitute this group of birds.
