''Morotopithecus bishopi'' is a species of fossil ape discovered in Moroto, Uganda.〔 The phylogenetic status of ''Morotopithecus bishopi'' is debated to the extent that it challenges established views on the connection between Miocene primates and extant hominids (i.e. great apes).〔(plosone )〕 Parsimonious phylogenetic analyses indicate ''Morotopithecus'' is more derived than ''Proconsul'',〔Maclatchy, L. (2004), ''The oldest ape''. Evolutionary Anthropology: Issues, News, and Reviews, 13: 90–103. () (2012-01-03 )〕 ''Afropithecus'', and ''Kenyapithecus'', but less derived than ''Oreopithecus'', ''Sivapithecus'', and ''Dryopithecus''. ''Morotopithecus'' thus seems to be a sister taxon to extant great apes while ''Hylobates'' (gibbons) seem to have branched off before this clade appeared. However, gibbons are believed to have branched off while ''Morotopithecus'' is dated to more than . In a comparison of teeth characteristics of ''Morotopithecus'' to ''Afropithecus'' the results showed little difference, plus evidence gathered from cranial comparisons also indicate that the two genera may be the same, a conclusion of limited confidence due to the lack of evidence to produce a complete anatomy for both (Patel, Grossman 2005).〔Biren A.
