Description of new mandibular remains of Microcolobus from Nakali (ca. 10 Ma, Kenya): implications on the evolution of Miocene colobines.

The paper describes new mandibular remains of Microcolobus from Nakali, Kenya, and finds they belong to a single species, Microcolobus tugenensis, with traits suggesting it is a stem Colobinae.

Anatomy of the mandibular corpus of extant cercopithecids : taxonomy and variation

This study uses geometric morphometrics to analyze mandibular corpus shape variation in cercopithecids, distinguishing taxa at multiple levels and identifying patterns of allometry, sexual dimorphism, and phylogenetic signal.

Anatomy of the mandibular symphysis of extant cercopithecids: taxonomy and variation

This study quantifies symphysis shape variation in extant cercopithecids to assess its utility for taxonomy, finding significant differences at subfamilial, tribal, and genus levels.
