This paper presents information on the cranial and dental anomalies observed in the crania of three species of platyrrhine monkeys collected in Nicaragua. Cranial anomalies that are discussed include plagiocephaly, bregmatic fontanelle bones, Wormian bones, cranial trauma, and heterotopic bones. Among the dental anomalies that were studied were the following: crazing caries, periodontal and pulpal disorders, alveolar thinning, mechanical loss, excessive attrition, shear bite, impacted molars, supernumerary teeth, congenital agencies, congenital crown aberration, and irregular placement.
