This research activity focuses on the Cercopithecidae family, which is a group of primates that includes macaques, baboons, and mandrills. The study aims to understand the evolutionary history and diversity of this family, with a focus on the fossil record. The research will involve the analysis of fossil specimens, including mandibles and postcranial bones, to reconstruct the phylogenetic relationships within the Cercopithecidae family. The findings of this study will contribute to our understanding of the evolution of primates and the diversity of life on Earth.
