Livyatan is an extinct genus of macroraptorial sperm whale containing one known species: L. The genus name was inspired by the biblical sea monster Leviathan , and the species name by Herman Melville , the author of the famous novel Moby-Dick about a white bull sperm whale. It is mainly known from the Pisco Formation of Peru during the Tortonian stage of the Miocene epoch , about 9. It was a member of a group of macroraptorial sperm whales or "raptorial sperm whales" and was probably an apex predator , preying on whales, seals and so forth. Characteristically of raptorial sperm whales, Livyatan had functional, enamel -coated teeth on the upper and lower jaws, as well as several features suitable for hunting large prey. Livyatan ' s total length has been estimated to be about The teeth of Livyatan measured

The Livyatan silhouettes in this image represent two different size estimates by Lambert et al. Because modern-day sperm whales have elongated skulls with variable lengths based on sex and age, Lambert et al. Doing so produced estimates of

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. Range : The only known specimen of Livyatan was reported from Peru, indicating that it inhabited the southeastern Pacific Ocean.

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. Livyatan melvillei , named after the Biblical sea monster and the author of Moby Dick , was a giant sperm whale that has just been discovered by Belgian scientist Olivier Lambert. At between It feeds through suction, relying on a rush of water to carry its prey into its open mouth. This was no suction feeder! Livyatan clearly grabbed its prey with a powerful bite, inflicting deep wounds and tearing off flesh as killer whales do, but with a skull three times bigger. Livyatan was at the very top of the food chain and it must have needed a lot of food.

Livyatan is a genus of prehistoric marine mammals that lived during the Miocene Epoch approximately 12 to 13 million years ago. However, fragmentary remains have also been found in other locations in both South and North America. This real-life aquatic beast was roughly the same size as modern sperm whales but had enormous teeth in its jaws and other features, suggesting that it could hunt large marine animals, including other whales. Hence, studying it can provide some fascinating insights into how this group of marine mammals lived and the evolution that led to their current form. Livyatan was a large marine mammal related to modern sperm whales. It also had many morphological similarities to sperm whales. The weight has been estimated to be about 57 tonnes, making it the largest fossil sperm whale ever found. It also had enormous teeth in its jaws that reached lengths up to The enamel-coated teeth were conical and curved slightly backward, making them ideal for grasping and holding onto prey. Experts think it was capable of hunting the largest prey in the Miocene oceans, thanks to a bite larger than that of any other tetrapod.

Article Talk. Livyatan lived from the Miocene to the Pliocene , the same time as Megalodon. The whale may have interacted with the large extinct shark megalodon Otodus megalodon , competing with it for a similar food source. Livyatan Livyatan melvillei Lambert et al. 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. It probably also preyed upon sharks, seals, dolphins and other large marine vertebrates, occupying a niche similar to the modern killer whale Orcinus orca. Archived from the original on 3 July Additionally, the relative size of the attachment area for the temporalis - the primary jaw closing muscle - is much larger relative to skull size than in Physeter , and is similar to that of the killer whale Orcinus orca. Unlike the modern sperm whale, Physeter macrocephalus , L. Journal of Paleontology.

The biggest prehistoric whale that ever lived, and a pound-for-pound match for the giant shark Megalodon, Leviathan did its Biblical namesake proud.

Nature News. The specimen L. Locomotion : Although most of the skeleton of Livyatan is unknown, primitive sperm whales of a similar evolutionary grade, like Zygophyseter ,have skeletons that are much like those of modern sperm whales. Livyatan was an apex predator , and probably had a profound impact on the structuring of Miocene marine communities. This was the opposite for the back teeth, and the biggest diameters for these teeth were around PMC Erich Fitzgerald and team are currently studying the specimen. It was discovered by a researcher on a school field trip. Range : The only known specimen of Livyatan was reported from Peru, indicating that it inhabited the southeastern Pacific Ocean. Specific soft tissue details that affect the appearance of the head, like the size and shape of the melon and spermaceti organ , are unknown. Lambert et al. Livyatan was classified as a member of the group Physeteroidia, which includes modern day Sperm Whales.
