Bone weathering in guanaco and Greater Rhea

I28-R145-3277_oai2025-11-17 Gutiérrez, María A. González, Mariela E. Álvarez, María C. Massigoge, Agustina Kaufmann, Cristian A. 2016-10-01 Bone weathering has been widely used in taphonomic and zooarchaeological analyses given its importance in assessing the integrity and the depositional context of archaeological materials. In this paper we present the results of a long-term experimental study undertaken on bones from guanacos of three different age classes, as well as an adult Greater Rhea, at eight years of exposure. The aim of this research was to evaluate if weathering differentially affected bones from both species, across the different age classes, and on diverse skeletal parts from the same carcass. Our results indicated that, in general terms, rhea bones weathered faster than the skeletal parts of guanaco belonging to the same age group. Likewise, guanaco bones belonging to immature individuals showed higher weathering rates than those from the adult, and after two years of exposure all the skeletal parts of the three guanacos presented some degree of weathering. Furthermore, guanaco skulls and teeth were the most affected elements across all three age classes. Finally, under increased exposure time, the axial skeleton showed slightly higher weathering stages than the appendicular skeleton. These preliminary results contribute to improving our understanding of the complexity inherent to the weathering process, while also building a more solid taphonomic database against which to model our archaeological expectations. La meteorización es una variable ampliamente utilizada en los análisis zooarqueológicos y tafonómicos, dada su utilidad para evaluar la integridad y el contexto de depositación de los materiales arqueológicos. En este artículo presentamos los resultados de un estudio experimental de largo plazo sobre huesos de guanaco de tres categorías etarias y de un ñandú adulto luego de ocho años de exposición. El objetivo de este trabajo es evaluar si la meteorización afecta diferencialmente a los huesos de estos dos taxones, a las categorías etarias y a los distintos elementos del esqueleto. En términos generales nuestros resultados indican que la mayoría de los huesos del ñandú adulto se meteorizan más rápido que los del guanaco de la misma edad; los individuos inmaduros de guanaco registran tasas más altas de meteorización que el adulto; todos los huesos de los guanacos presentan algún grado de meteorización a los dos años de exposición; cráneos y dientes fueron los elementos más afectados por la meteorización para los guanacos de las tres clases de edad; y el esqueleto axial de guanaco presenta estadios de meteorización ligeramente superiores al del apendicular a medida que aumenta el tiempo de exposición. Estos resultados preliminares contribuyen a mejorar nuestro entendimiento sobre la complejidad del proceso de meteorización, así como a la conformación de un cuerpo de información relevante para la generación de expectativas arqueológicas. application/pdf https://revistascientificas.filo.uba.ar/index.php/Arqueologia/article/view/3277 10.34096/arqueologia.t22.n0.3277 spa Instituto de Arqueología, Facultad de Filosofía y Letras, Universidad de Buenos Aires https://revistascientificas.filo.uba.ar/index.php/Arqueologia/article/view/3277/3017 Arqueología; Vol. 22 No. 3 (2016): September-December; 57-84 Arqueología; Vol. 22 Núm. 3 (2016): septiembre-diciembre; 57-84 1853-8126 0327-5159 Meteorización Estudio experimental Guanaco Ñandú Desarrollo ontogénico Weathering Experimental study Guanaco Greater Rhea Ontogenetic development Bone weathering in guanaco and Greater Rhea Meteorización ósea en restos de guanaco y ñandú info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=arqueo&d=3277_oai |

Bone weathering has been widely used in taphonomic and zooarchaeological analyses given its importance in assessing the integrity and the depositional context of archaeological materials. In this paper we present the results of a long-term experimental study undertaken on bones from guanacos of three different age classes, as well as an adult Greater Rhea, at eight years of exposure. The aim of this research was to evaluate if weathering differentially affected bones from both species, across the different age classes, and on diverse skeletal parts from the same carcass. Our results indicated that, in general terms, rhea bones weathered faster than the skeletal parts of guanaco belonging to the same age group. Likewise, guanaco bones belonging to immature individuals showed higher weathering rates than those from the adult, and after two years of exposure all the skeletal parts of the three guanacos presented some degree of weathering. Furthermore, guanaco skulls and teeth were the most affected elements across all three age classes. Finally, under increased exposure time, the axial skeleton showed slightly higher weathering stages than the appendicular skeleton.
