In Depth

       Once described as a new species of Protocetus,‭ ‬the holotype remains were elevated to genus level in‭ ‬1975.‭ ‬Although a different genus,‭ ‬Andrewsiphius would have still been a primitive toothed whale form similar to the more famous Protocetus.‭ ‬The rear‭ ‬limbs would still have been visible on the outside of the body,‭ ‬while propulsion was provided by the up and down undulation of the tail.
