State of the knowledge of baculum and baubellum occurrence. Comparison between our baculum (left) and baubellum (right) occurrence data coverage of primate phylogeny. Green lines indicate the presence of ossa genitalia. Red lines indicate the absence of ossa genitalia. Grey lines stand for ‘omitted data’ (i.e., all those species for which neither absence nor presence of genital bones was ever stated). Phylogeny by Springer71, dropped.
