In Depth

       Gaviacetus is usually interpreted as a protocetid,‭ ‬a very primitive kind of whale that would have still possessed legs for terrestrial locomotion,‭ ‬though in the past Gaviacetus has also been considered to be a possible basilosaurid.‭ ‬However,‭ ‬at the time of writing there is little evidence to conclusively prove that Gaviacetus was a basilosaurid.‭ ‬There was once another species of Gaviacetus called G.‭ ‬sahnii,‭ ‬but this has since been re-named as a new genus,‭ ‬Kharodacetus.
