Note : This species was originally named Leviathan melvillei in the summer of As it turned out, the name Leviathan had already been used for a mastodon, an extinct type of elephant. Rules established by the International Code of Zoological Nomenclature prohibit this, otherwise confusing situations could develop because different species share the same name. Thus the authors renamed their new species Livyatan , which is the original Hebrew spelling Leviathan is the English spelling.

Livyatan Livyatan melvillei Lambert et al. Size : Body length of The skull is 3 metres long. Livyatan is an extinct species of physeteroid whale, which lived during the Miocene epoch, approximately million years ago. In November , fossil remains of Livyatan melvillei were discovered in the sediments of Pisco formation at Cerro Colorado, 35 kilometres south-southwest of Ica , Peru. The remains include a partially preserved skull with teeth and mandible. Rotterdam Natural History Museum researcher Klaas Post stumbled across them on the final day of a field trip there in November

Update : This animal has been renamed! It used to be Leviathan until someone pointed out to the authors that the name had already been taken! But living whales have it easy. Those that swam off the coast of Peru around 12 million years ago were hunted by a far bigger predator, a recently discovered animal with a very appropriate name: Livyatan.

But unlike modern Carnivorous whales, Livyatan hunted alone. The holotype skull of Livyatan was about 3 m 9. The geological formation where the whale has been found has also preserved a large assemblage of marine life, such as sharks and marine mammals. PMID Toggle limited content width.

This group is known for having large, functional teeth in both the upper and lower jaws, which were used in capturing large prey, and had an enamel coating.
