Note : Livyatan size 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.

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 The fossils have been dated at 12—13 million years old and were prepared in Lima, Peru, and are now part of the collection of the Natural History Museum there. Researchers originally assigned the English name of the biblical monster Leviathan to this prehistoric whale as Leviathan melvillei , dedicating the discovery to Herman Melville, author of Moby-Dick—the researchers behind the excavation of L. However, the scientific name Leviathan was a junior homonym of Leviathan Koch, for a genus of mastodon. Junior homonyms need to be replaced with new names, except under certain special circumstances. In August , the authors rectified this situation by coining a new genus name for the whale, Livyatan , from the original Hebrew spelling.

Livyatan , sometimes known as the killer sperm whale or the dire whale , is an extinct genus of physeteroid whale, which lived during the Miocene epoch, approximately million years ago. The type species is the only known species, being L. The skull of Livyatan is 3 metres 10 feet long. Unlike the modern sperm whale, Physeter macrocephalus , L. The jaws of L. The teeth of L. Larger 'teeth' tusks are known, such as walrus and elephant tusks, but these are not used directly in eating.

The biggest prehistoric whale that ever lived, and a pound-for-pound match for the giant shark Megalodon, Leviathan did its Biblical namesake proud. Below, you'll discover 10 fascinating Leviathan facts. The genus name Leviathan— after the fearsome sea monster in the Old Testament—seems more than appropriate for a giant prehistoric whale. The trouble is, shortly after researchers assigned this name to their discovery in , they learned that it had already been used for a genus of mastodon erected a full century before. The quick fix was to substitute the Hebrew spelling Livyatan, though for all practical purposes most people still refer to this whale by its original name. Extrapolating from its foot-long skull, paleontologists believe that Leviathan measured upwards of 50 feet from head to tail and weighed as much as 50 tons, about the same size as a modern sperm whale. This made Leviathan by far the largest predatory whale of the Miocene epoch, about 13 million years ago, and it would have been secure in its position at the top of the food chain if not for the equally ginormous prehistoric shark megalodon see next slide. Because of the lack of multiple fossil specimens, we're not sure exactly how long Leviathan ruled the seas, but it's a sure bet that this giant whale occasionally crossed paths with the equally giant prehistoric shark megalodon. While it's dubious that these two apex predators would have deliberately targeted one another, they may well have butted heads in the pursuit of the same prey, a scenario explored in-depth in Megalodon vs.

The authors opted to use the relationship between the bizygomatic width distance between the opposite zygomatic processes of the skull and body length because of the variable rostrum length in modern sperm whales and the rostrum of Livyatan being proportionally shorter. Archived from the original on 2 December In in Beaumaris Bay , Australia, a large sperm whale tooth measuring 30 cm 1 ft , specimen NMV P, was discovered in Pliocene strata by a local named Murray Orr, and was nicknamed the "Beaumaris sperm whale" or the "giant sperm whale". Combine Archived from the original on 11 December You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. Livyatan probably occupied the same niche as the modern killer whale Orcinus orca. The curvature of the teeth decreased from front to back, and the lower teeth were more curved at the tips than the upper teeth. The tooth sockets were smaller in the lower jaw than they were in the upper jaw, and they were circular in shape, except for the front sockets which were more ovular. The jaws of L. The most robust teeth in Livyatan were the fourth, fifth and sixth teeth in each side of the jaw.

Leviathan, properly known as Livyatan melvillei, is a prehistoric whale which lived approximately 13 million years ago during the Miocene Period.

But unlike modern Carnivorous whales, Livyatan hunted alone. It is mainly known from the Pisco Formation of Peru during the Tortonian stage of the Miocene epoch , about 9. Archived from the original on 6 May The vomer reached the tip of the snout, and was slightly concave, decreasing in thickness from the back to the front. The species name melvillei is a reference to Herman Melville , author of the book Moby-Dick , which features a gigantic sperm whale as the main antagonist. Fossil remains of many other animals—including baleen whales, beaked whales, dolphins, porpoises, sharks, sea turtles, seals and sea birds—have been found at the same site where the remains of L. Gamma However, additional isolated large sperm whale teeth from other locations including California, Australia, Argentina and South Africa have been identified as a species or possible close relative of Livyatan. Because of this, along with only isolated teeth being available, the palaeontologists chose to assign an open nomenclature, identifying both specimens as aff. Sensory Abilities : The skull of Livyatan has a large depression on the top of the skull the 'supracranial basin' , which in modern sperm whales houses the 'spermaceti organ' and the melon, two soft tissue organs which function in echolocation.
