Document Summary
Cranial morphology: size, post-orbital bar/closure, surface structures. Dental morphology: dental formula, tooth size, tooth morphology bilophodonty, y-5, dietary adaptation, taxon-specific morphology (e. g. , gap for rhinarium, tooth comb, * strepsirhines-eye socket is not fully closed, tooth comb only 6 teeth make up comb. Haplorhines- there is full closure around the eye. Typical nwm (squirrel monkey) atypical nwm (tamarin) (2:1:3:3) (2:1:3:2) typical catarrhine (chimp) (2:1:2:3) * cercopithecoid (baboon) upper and lower post-canine dentition. Factors affecting diet: climate- depends on where they live, seasonality whats around that time of the year, geography location, competition, body size, activity pattern. Functional morphology: foods consumed when preferred food items are unavailable. Mouse lemur (microcebus) insectivorous *teeth that are dagor like to puncture ex co skeleton. Gorilla (gorilla) folivorous* designed to eat leaves teeth act like sisors when enamel wears away. Orangutan (pongo) hard object frugivore and a lot of the food has hard covering crenulations. *is most common in animals who eat fruits.
