These early cetaceans became gradually better adapted for swimming than for walking on land, finally evolving into fully marine cetaceans.
Basilosaurus (meaning "king lizard") is a genus of large, predatory, prehistoric archaeocete whale from the late Eocene, approximately 41.3 to 33.9 million years ago (mya). First described in 1834, it was the first archaeocete and prehistoric whale known to science. [2] Fossils attributed to the type species B. cetoides were discovered in the ...

The taxon would have had powerful jaw musculature and probably fed on large prey by seizing it and puncturing it with its robust teeth.
