The 2.1.2.3 dental formula is a characteristic feature of haplorrhines, including fossil forms and extant anthropoids, as opposed to strepsirrhines which have a 2.1.3.3 dental formula. Propliopithecids are considered to be a group of early catarrhine primates (Old World monkeys and apes), which shared this dental formula with other haplorrhines. Neither of the other options is true for haplorrhines or propliopithecids.
