It is the largest pliosaur ever to be discovered. In 1999, Liopleurodon was featured in an episode of the 1999 BBC television series Walking with Dinosaurs, where its was claimed to be 25 meters (80 feet) long and up to 150 tons. Thanks to its limited fossil remains, there's still a lot we don't know about the everyday life of Liopleurodon. How did the remains of Liopleurodon wash up in France, of all places? Like many prehistoric animals discovered in the 19th century, Liopleurodon was named on the basis of very scanty fossil evidence, exactly three teeth, each of them almost three inches long, excavated from a town in France in 1873. As deadly as they were, pliosaurs like Liopleurodon were no match for the relentless progress of evolution. The Liopleurodon could easily pluck a Eustreptospondylus from the land and rip it to shreds. A male Liopleurodon is featured in Sea Rex where he loses an eye and chases a plesiosaur before being dealt a fatal blow from the tail of a Leedsichthys. The … With its four broad, flat, long flippers, Liopleurodon could thrust itself through the water at a considerable clip and, perhaps more important for hunting purposes, quickly accelerate in pursuit of prey when circumstances demanded. In ARK: Survival Evolved Mobile, a Liopleurodon's lifespan can be extended through Tame Chronicling. Teeth length= 60cm. Two adult Eustreptospondylus (in a twist of irony) who survived the storm feed upon it. Adult length of 25 metres(80 feet) with a skull an incredible 5 metres (16 feet) long.Liopleurodons weight is difficult to estimate but it may have been 150 tonnes Liopleurodon was the titan of the mid-jurassic. It measures 7 meters but the largest specimens measure a little over 10 meters. of the mid-jurassic. 80 Comments. [9], The discovery of a very large pliosaur was announced in 2002, from Mexico, nicknamed the 'Monster of Aramberri'. Unfortunately, the producers depicted Liopleurodon with a grossly exaggerated length of over 80 feet, while a more accurate estimate is 30 feet. [16] In fairness to the program's producers, it should be noted that the 3 meter mandible of the Oxford Pliosaurus macromerus was, at the time of the series, classified as belonging to a Liopleuridon macromerus (it was not re-classified as Pliosaurus macromerus until 2003). A vast assortment of pliosaurs and plesiosaurs plied the world's oceans during the Jurassic period, achieving a worldwide distribution comparable to that of modern sharks. Since then, marine reptile enthusiasts have found themselves saddled with a not particularly attractive or transparent name (pronounced LEE-oh-PLOOR-oh-don), which translates from the Greek as "smooth-sided teeth.". The name of the Liopleurodon, three large, 70 mm teeth and these poor remnants were based on HE Sauvage in 1993 [1]. ", The Name Liopleurodon Means "Smooth-Sided Teeth", Estimates of Liopleurodon's Size Have Been Greatly Exaggerated, Liopleurodon Was a Type of Marine Reptile Known as a "Pliosaur", Liopleurodon Was the Apex Predator of Late Jurassic Europe, Liopleurodon Was an Unusually Fast Swimmer, Liopleurodon Had a Highly Developed Sense of Smell, Liopleurodon Wasn't the Largest Pliosaur of the Mesozoic Era, Like Whales, Liopleurodon Had to Surface to Breathe Air, Liopleurodon Was the Star of One of the First Viral YouTube Hits, Liopleurodon Went Extinct by the Start of the Cretaceous Period, Plesiosaur and Pliosaur Pictures and Profiles, Plesiosaurs and Pliosaurs - The Sea Serpents, Plesiosaurus, the Long-Necked Marine Reptile, Learn About the Different Dinosaur Periods, The 20 Biggest Dinosaurs and Prehistoric Reptiles, 10 Facts About Elasmosaurus, Ancient Marine Reptile. Although pliosaurs like Liopleurodon didn't represent the evolutionary peak of underwater propulsion, which is to say, they weren't as speedy as modern Great White Sharks, they were certainly fleet enough to fulfill their dietary needs. [3] L. rossicus has been found in Russia's Volgian region. A tooth located near Boulogne-sur-Mer, a layer from the Callovian, Liopleurodon ferox to France, another from Charly, Liopleurodon grossouvrei to France, France discovered here in Caen, initially described as Poikilopleuron, Sauvage Liopleurodon Bucklandi). Currently, there are three recognized species within Liopleurodon. Two species of Liopleurodon, L. ferox and L. pachydeirus, lived during the Callovian stage of the Middle Jurassic Period (c. 160 million to 150 million years ago mya), while the third, L. rossicus, lived during the Late Jurassic. [8], The largest known Liopleurodon skull belongs to L. ferox. Because fossils are rare (meaning that it is unlikely we would happen to find the largest example of a particular ancient species), and because pliosaurs, like dinosaurs, did not stop growing with age,[17] it is certainly likely that very old individuals of L. ferox grew to a size somewhat exceeding that of the largest known specimen, perhaps to 25 meters (80 feet) and 5-6 metric tons (7.7 - 8.8 tons). Pliosaurs, of which Liopleurodon was a classic example, were a family of marine reptiles characterized by their elongated heads, relatively short necks, and long flippers attached to thick torsos. 12K Views. Most peoples' first encounter with Liopleurodon was in 1999 when the BBC featured this marine reptile in its popular Walking with Dinosaurs TV series. Charlie the Unicorn quickly garnered tens of millions of page views and spawned three sequels, in the process doing as much as Walking with Dinosaurs to cement Liopleurodon in the popular imagination. In the program, a gigantic Liopleurodon was depicted attacking and devouring the theropod dinosaur Eustreptospondylus and some Ophthalmosauruses, before becoming beached during a typhoon and suffocating under its own weight. I am confused most books say liopleurodon was 80 ft.? [5] Only L. ferox is known from more or less complete skeletons. Liopleurodon ferox Named by: Henri Emile Sauvage, 1873 Diet: Carnivore (Prey included ammonites, fish such as the 50-foot Leedsichthys, sharks such as Hybodus, thallatosuchian marine crocodilians such as Metriorhynchus, plesiosaurs such as Cryptocleidus, and ichthyosaurs such as Ophthalmosaurus) Type: Pliosaur (short-necked plesiosaur) Size: 23 feet (7 … Four 10 feet long flippers- dont know if these were used as weapons. In the program, a gigantic Liopleurodon was depicted attacking and devouring the theropod dinosaur Eustreptospondylus and some Ophthalmosauruses, before becoming beached during a typhoon and suffocating under its own weight. Liopleurodon (/ ˌ l aɪ oʊ ˈ p l ʊər ə d ɒ n /; meaning 'smooth-sided teeth') is a genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs.The two species of Liopleurodon lived from the Callovian Stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic Period (c. 166 to 155 mya). An enormous marine predator, that comes near to matching the size of modern whales. Liopleurodon would even kill and eat others if its own kind. Liopleurodon previously appeared in the second Primeval novel. To judge by its weight (up to 10 tons for a full-grown adult), Liopleurodon was clearly the apex predator of its marine ecosystem, relentlessly gobbling fish, squids, and other, smaller marine reptiles. It was added as a part of the March 16th, 2016 update. One convincing hypothesis based on the forward-facing position of the nostrils on its snout is that this marine reptile had a well-developed sense of smell, and could locate prey from a fair distance away. Although Liopleurodon was certainly a contender for the title of "biggest pliosaur ever," other candidates include the contemporaneous Kronosaurus and Pliosaurus, as well as a couple of yet-unnamed pliosaurs recently discovered in Mexico and Norway. [6][7] Studies of the skull have shown that it could probably scan the water with its nostrils to ascertain the source of certain smells. EVIDENCE: Found mostly near England and France but possibly also in Chile. The problem seems to be that Walking with Dinosaurs extrapolated from the size of Liopleurodon's skull; as a rule, pliosaurs had very big heads compared to the rest of their bodies. [11]) However, the Oxford mandible has since been re-classified as Pliosaurus macromerus.[12]. Nature Wiki is a FANDOM Lifestyle Community. Unlike the Cryptoclidus, the Liopleurodon is far too heavy to get on to the land, if a Liopleurodon does get on land which is most unlikey, it will not be able to return to the sea. and was originally estimated (Tarlo, 1960) to belong to an animal about 25 meters (80 feet) in length. The Liopleurodon is an ambush predator. According to a 2008 article written for, the popularity of Liopleurodon, which had previously been more obscure in popular culture than other well-known pliosaurs such as Kronosaurus, experienced an upsurge following its mention in the online animated short Charlie the Unicorn. A 100-foot long Liopleurodon appears in the novel Meg: Hell's Aquarium and is depicted as having evolved gills and being bigger than Megalodon. A cautious estimate say it measures 12 meters long. Most peoples' first encounter with Liopleurodon was in 1999 when the BBC featured this marine reptile in its popular Walking with Dinosaurs TV series. [14] Later work (Noe, 2004) cast doubt on the model used to estimate the length of Liopleurodon, which had been based on the 5 meter skull length to body length ratio found in the famous (and morphologically similar) Kronosaurus skeleton mounted at Harvard's Museum of Comparative Zoology. A Liopleurodon is the main antagonist in The Land Before Time IX: Journey to the Big Water and along with other swimming carnivores, such as Cretoxyrhina and Hydrotherosaurus, are called Swimming Sharpteeth or Sharptooth Swimmers. It was an apex predator of the Middle to Late Jurassic seas that covered Europe. 3-4 finds near Singapore to China. As discussed in slide #3, it can be very difficult to extrapolate the length and weight of marine reptiles from limited fossil remains. It was widely reported as belonging to Liopleurodon, however no taxonomic conclusions could be made due to poor preservation and fact that the remains were of a partial vertebral column (non-diagnostic). Bob Strauss is a science writer and the author of several books, including "The Big Book of What, How and Why" and "A Field Guide to the Dinosaurs of North America. by the BBC Television series, Walking With Dinosaurs that Liopleurodon may have reached lengths of 25 m (80 feet), the largest known specimens suggest a maximum length of 17 m (56 feet)., Adult length of 25 metres(80 feet) with a skull an incredible 5 metres (16 feet) long.Liopleurodons weight is difficult to estimate but it may have been 150 tonnes. Analysis of two mostly complete adult L. Ferox skeletons showed that the ratio of skull length to body length was more in the range of 1:9 or even 1:8, leading Noe to estimate that Tarlos's L. Ferox was only about 24 meters (75 feet), with a corresponding weight of about 2.5 metric tons (2.75 tons).15 (The original reconstruction of Harvard's Kronosaurus Queenslandicus is now known to have included too many vertebrae, resulting in a size estimate of ~ 40 feet as well as derivation of an erroneous skull length to body length ratio. You can opt-out at any time. Nothing could hurt it. The only animal I can think of that would have stood a chance in a large group is killer whales- possibly.
