It is extensive in most primates (except for great apes) and nearly all mammals. In these animals, the subarcuate fossa houses a part of the brains cerebellum, the petrosal lobe. see [http://www.ncbi.nlm.nih.gov/pubmed/3207165?ordinalpos=10&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum] [http://www.ncbi.nlm.nih.gov/pubmed/18395770?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum] ==External links== * {{RocheLexicon|34257.000-2}} {{Gray's}} {{Skull}} {{musculoskeletal-stub}}
