Resumen:
The bone texture of Rhea americana was evaluated through the examination of a postnatal ontogenetic series. The hind limb bone surfaces of specimens of one, three and five months old, and adults were compared to characterize each stage according to the morphological features generated by their differential ossification. The results suggest a similar process of tissue maturation concerning neognathous birds, although with some differences. A spongy or striated surface with abundant pores in the femur and longitudinal grooves in the tibiotarsus and tarsometatarsus characterizes chicks.Vascularity decreases, and the bone texture gradually changes acquiring a more homogeneoussurface, to eventually reach the smooth appearance of adult bones. The establishment of particular textures corresponding to different bones and ontogenetic stages permits the accurate interpretation of remains in ecological, archaeological and paleontological contexts in which bones are fragmented and/or incomplete.
