In Depth

       Archaeodobenus is an ancient relative of the walrus.‭ ‬Unlike the walrus however,‭ ‬Archaeodobenus did not have the large tusks that are the most familiar feature of‭ ‬the walrus.‭ ‬Instead,‭ ‬Archaeodobenus simply had slightly enlarged canine teeth,‭ ‬and‭ ‬an overall appearance more similar to that of a sea lion.
