| In Basilosaurus, nearly all of these structures lay within the body wall, and most parts were immobile. |
|
| Then they found tiny legs on a 50-foot long, 40-million year old whale named Basilosaurus. |
|
| Although Basilosaurus possessed a fluke and peduncle, Buchholtz dismisses these features because they are too short relative to body length. |
|
| The first of the truly gigantic whales, Basilosaurus had the serpentine shape of a sea monster and short, sharp teeth for hunting sharks and other prey. |
|
| A rhino-sized, wolf-like carnivore, Andrewsarchus is actually a relative of our familiar hoofed animals and a distant relative of the early whale, Basilosaurus. |
|
| The direct ancestors of today's cetaceans are probably found within the Dorudontidae whose most famous member, Dorudon atrox, lived at the same time as Basilosaurus. |
