The occipital bone and the foramen magnum are salient structures of the skull; which have been widely studied in various species due to variability associated with their morphology and the clinico-paleontological significance of related ‘anomalies’. The aim of this study was to discuss and review literatures on the development, form and construction of the structures in tropical raccoon dogs (Nyctereutes procyonoides cancrivora) a species noted as most variably sized. Relevant aspects of predisposition to and diagnosis of neuro-pathologies related to the occipital area as well as species variations in composite architecture of the bone and foramen magnum in evolutionary perspectives. This review postulates elements of developmental instability exist with predisposition to dysmorphologies in the occipital area of this species and suggests that this investigation may be of value in canalization, ontogenetic variability and population studies and serve as important research data in cranio-facial modeling for species anthropometry and taxonomic classifications.
