Abstract
Nothrotherium maquinense, an extinct sloth species that existed alongside other megafauna during the Pleistocene, has been a subject of intense debate regarding various aspects of its life. This study integrates an examination of specific forearm bone fracture (paleopathology) with forelimb functional indices (paleoecology) in N. maquinense in order to infer its likely mode of locomotion and substrate preferences. Our findings provide compelling evidence suggesting that N. maquinense possessed climbing abilities and likely had a semi-arboreal lifestyle. Additionally, we report the first occurrence of calcium pyrophosphate deposition disease (CPPD) in this species, indicating that this type of arthritic condition was present in this sloth.
期刊介绍:
Journal of Mammalian Evolution is a multidisciplinary forum devoted to studies on the comparative morphology, molecular biology, paleobiology, genetics, developmental and reproductive biology, biogeography, systematics, ethology and ecology, and population dynamics of mammals and the ways that these diverse data can be analyzed for the reconstruction of mammalian evolution. The journal publishes high-quality peer-reviewed original articles and reviews derived from both laboratory and field studies. The journal serves as an international forum to facilitate communication among researchers in the multiple fields that contribute to our understanding of mammalian evolutionary biology.
