This one has to be pronounced ak-e-LOH-uh-SAWR-us, NOT a-KEE-lo-SAWR-us, as I recall hearing. The name derives from Greek Akheloos (the two o's being pronounced separately), which Latin rules turn into Achelous (divided as a-che-lo-us, short e, long o and short u), again pronounced in four syllables with the accent on the next-to-last, that is the one with the long o. All sources I have checked indicate that ak-e-LOH-us is the accepted English pronunciation of the Latin name. Since the scientific name Achelousaurus was formed by arbitrarily combining Achelous and saurus instead of using the stem-form Achelo-, the "u" needs to pronounced.
