Thorn lesions in a modern osteological collection of guanaco (Lama guanicoe): a new paleoenviromental proxy and its implications for archaeofaunal assemblages
This paper provides detailed analysis of thorn lesions found in lower limb elements of a modern osteological collection of guanaco (Lama guanicoe). Four types of lesions were recorded: (1) thorns visible on the bone surface, (2) bony reaction with relief, (3) small negative scars, and (4) medium neg...

| Sumario: | This paper provides detailed analysis of thorn lesions found in lower limb elements of a modern osteological collection of guanaco (Lama guanicoe). Four types of lesions were recorded: (1) thorns visible on the bone surface, (2) bony reaction with relief, (3) small negative scars, and (4) medium negative scars. The methods used to recognize, record, and quantify these lesions are presented. As a result, 35 of the 36 individuals analyzed contained one or more types of lesions. The highest concentrations of lesions were recorded on the anterior view of the metacarpal shafts. All the age ranges were affected by lesions; however, individuals between the ages of 1-3 years were the most affected, while ages 0-1 contained the least amount of lesions. To provide examples of how thorn lesions can be identified and used as a paleoenvironmental proxy in the fossil record, two archaeological sites from different phytogeographic provinces were analyzed: Bajo de la Quinta (Monte phytogeographic province) and Calera (Pampa phytogeographic province). Results found that 25% of the elements from the Bajo de la Quinta site contained lesions, while none of the elements from the Calera site showed evidence of lesions. When detectable in the fossil record, thorn lesions can provide an indirect approximation of the paleoenviroment. |
