She winced and gave a pained expression at the sight of it. [23][29] The genus Otodus is ultimately derived from Cretolamna, a shark from the Cretaceous period. The shark emerges, and bites parts of the log off, making Petrie cling to Littlefoot's neck. [61] The shark was an opportunist and piscivorous, and it would have also gone after smaller fish and other sharks. Another nearly complete associated megalodon dentition was excavated from the Yorktown Formations in the United States, and served as the basis of a jaw reconstruction of megalodon at the National Museum of Natural History (USNM). It was found in locations with a mean temperature ranging from 12 to 27 °C (54 to 81 °F), with a total range of 1 to 33 °C (34 to 91 °F), indicating that the global extent of suitable habitat should not have been greatly affected by the temperature changes that occurred.

[28]:55[33] The tooth met the jaw at a steep angle, similar to the great white shark. [25][28]:60 They asserted that O. megalodon could have reached a maximum of 20.3 meters (67 ft) in total length. Movies Land Before Time. It is considered to be the largest shark—as well as the largest fish—that ever lived. ... Aylene looked back for a moment to see where the Megalodon was, and a cold fear struck through her when she saw it turn around and head straight for them. [8], Mature male megalodon may have had a body mass of 12.6 to 33.9 metric tons (13.9 to 37.4 short tons), and mature females may have been 27.4 to 59.4 metric tons (30.2 to 65.5 short tons), assuming that males could range in length from 10.5 to 14.3 meters (34 to 47 ft) and females 13.3 to 17 meters (44 to 56 ft). [87] The cooling of the oceans during the Pliocene might have restricted the access of megalodon to the polar regions, depriving it of the large whales which had migrated there. [40] In 1989, a nearly complete set of megalodon teeth was discovered in Saitama, Japan. The average body size of baleen whales increased significantly after its disappearance, although possibly due to other, climate-related, causes. Fossilized teeth of an undetermined species of such physeteroids from Lee Creek Mine, North Carolina, indicate it had a maximum body length of 8–10 m and a maximum lifespan of about 25 years. [16][21]:1 The shark may have been able to open its mouth to a 75° angle, though a reconstruction at the USNM approximates a 100° angle. In biology A reduction in the diversity of baleen whales and a shift in their distribution toward polar regions may have reduced megalodon's primary food source. [40] A 2020 study—looking at the dimensions of the modern great white, mako, and Lamna sharks—suggested a 16 m (52 ft) megalodon would have had a 4.65 m (15.3 ft) long head, 1.41 m (4 ft 8 in) tall gill slits, a 1.62 m (5 ft 4 in) tall dorsal fin, 3.08 m (10 ft 1 in) long pectoral fins, and a 3.85 m (12 ft 8 in) tall tail fin. megalodon. It is highly unlikely a single cause did in Megalodon. [10][11] In comparison, the maximum recorded size of the great white shark is 6.1 meters (20 ft), and the whale shark (the largest living fish) can reach 18.8 m (62 ft). [28]:74–75, Megalodon were contemporaneous with whale-eating toothed whales (particularly macroraptorial sperm whales and squalodontids), which were also probably among the era's apex predators, and provided competition. Megalodon had a very robust dentition,[28]:20–21 and had over 250 teeth in its jaws, spanning 5 rows. [27], Megalodon has been portrayed in several works of fiction, including films and novels, and continues to be a popular subject for fiction involving sea monsters. [16] Though “megalodon” is an informal name for the shark, it is also often informally dubbed the "giant white shark",[20] the "megatooth shark", the "big tooth shark", or "Meg". [77][28]:77 In areas where their ranges seemed to have overlapped, such as in Pliocene Baja California, it is possible that megalodon and the great white shark occupied the area at different times of the year while following different migratory prey. By: Elise Lowing. Unlike great whites which target the underbelly of their prey, megalodon probably targeted the heart and lungs, with their thick teeth adapted for biting through tough bone, as indicated by bite marks inflicted to the rib cage and other tough bony areas on whale remains. [21]:88, In 2002, paleontologist Kenshu Shimada of DePaul University proposed a linear relationship between tooth crown height and total length after conducting anatomical analysis of several specimens, allowing any sized tooth to be used. [91] Such diversity presented an ideal setting to support a super-predator such as megalodon. The largest tooth in Jeremiah's possession had a root width of about 12 centimeters (4.7 in), which yielded 16.5 meters (54 ft) in total length. [102] The sequels to the book also star megalodon: The Trench, Meg: Primal Waters, Meg: Hell's Aquarium, Meg: Nightstalkers, Meg: Generations, and Meg: Origins,[97] and there is a film adaptation entitled The Meg released on 10 August 2018. For a list of all Sharptooth, see List of Sharpteeth in The Land Before Time. Sharptooth, Cera (formerly), Ozzy and Strut, Velociraptors, Dil and Ichy, Cryptoclidus, Megalodon, Plated Sharptooth, Allosaurus. It flings her off, and she is able to swim back to the log, right before the sharptooth just misses biting her. The Extinction of Megalodon. The Land Before Time V: The Mysterious Island is a 1997 direct-to-video animated adventure musical film produced and directed by Charles Grosvenor. [10] This is consistent with evidence that it was a mesotherm. He described his findings in the book The Head of a Shark Dissected, which also contained an illustration of a megalodon tooth. It comprises 150 vertebral centra, with the centra ranging from 55 millimeters (2.2 in) to 155 millimeters (6 in) in diameter. Meanest Sharptooth's death. [44], The first attempt to reconstruct the jaw of megalodon was made by Bashford Dean in 1909, displayed at the American Museum of Natural History. [108][109], Megalodon teeth are the state fossil of North Carolina. [10], Megalodon inhabited a wide range of marine environments (i.e., shallow coastal waters, areas of coastal upwelling, swampy coastal lagoons, sandy littorals, and offshore deep water environments), and exhibited a transient lifestyle. in South Africa). The inclusion of the Carcharocles sharks in Otodus would make it monophyletic, with the sister clade being Megalolamna. This is because transitional fossils have been found showing that Megalodon is the final chronospecies of a lineage of giant sharks originally of the genus Otodus which evolved during the Paleocene. Creation and development. [21]:87[35] Also because of this, the great white shark is the basis of its reconstruction and size estimation,[28]:57 as it is regarded as the best analogue to megalodon. similar to what Jaws was like, intentionally attacking creatures that a normal shark usually would not prey on. [101] Steve Alten's Meg: A Novel of Deep Terror portrays the shark having preyed on dinosaurs with its prologue and cover artwork depicting megalodon killing a Tyrannosaurus in the sea. [28]:55[55], The dental formula of megalodon is: 2.1.7.43.0.8.4. [25][33], The genus Carcharocles may be invalid, and the shark may actually belong in the genus Otodus, making it Otodus megalodon. [87][66][89] Fossil evidence confirms the absence of megalodon in regions around the world where water temperatures had significantly declined during the Pliocene. [41], Its large size may have been due to climatic factors and the abundance of large prey items, and it may have also been influenced by the evolution of regional endothermy (mesothermy) which would have increased its metabolic rate and swimming speed. However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous. [28]:71–75[12] A study focusing on calcium isotopes of extinct and extant elasmobranch sharks and rays revealed that megalodon fed at a higher trophic level than the contemporaneous great white shark. The tail fin would have been crescent-shaped, the anal fin and second dorsal fin would have been small, and there would have been a caudal keel present on either side of the tail fin (on the caudal peduncle). These may have occupied a niche similar to that of orcas before eventually being replaced by them. [103], Animal Planet's pseudo-documentary Mermaids: The Body Found included an encounter 1.6 mya between a pod of mermaids and a megalodon. [33] Their dietary preferences display an ontogenetic shift:[28]:65 Young megalodon commonly preyed on fish,[33] sea turtles,[61] dugongs,[21]:129 and small cetaceans; mature megalodon moved to off-shore areas and consumed large cetaceans. [89], Competition from other predators of marine mammals, such as macropredatory sperm whales which appeared in the Miocene, and killer whales and great white sharks in the Pliocene,[68][72][92] may have also contributed to the decline and extinction of megalodon. ", "Miocene sharks in the Kendeace and Grand Bay formations of Carriacou, The Grenadines, Lesser Antilles", "Largest Great White Shark Don't Outweigh Whales, but They Hold Their Own", "Sizing ocean giants: patterns of intraspecific size variation in marine megafauna", "Is the scaling of swim speed in sharks driven by metabolism? [6], One interpretation on how megalodon appeared was that it was a robust-looking shark, and may have had a similar build to the great white shark. [57] To support its large dentition, the jaws of megalodon would have been more massive, stouter, and more strongly developed than those of the great white, which possesses a comparatively gracile dentition. Miocene coprolite remains were discovered in Beaufort County, South Carolina, with one measuring 14 cm (5.5 in). The extinction of the shark appeared to affect other animals; for example, the size of baleen whales increased significantly after the shark had disappeared. Its chondrocranium, the cartilaginous skull, would have had a blockier and more robust appearance than that of the great white. [26] A 2019 assessment moves the extinction date back to earlier in the Pliocene, 3.6 mya. The jaws may have been blunter and wider than the great white, and the fins would have also been similar in shape, though thicker due to its size. Edit. Megalodon (The Land Before Time) N Nightmare Dragon (The Land Before Time) Nightmare Longneck (The Land Before Time) P Pachycephalosaurus (The Land Before Time) Plated Sharptooth; Purple Pterodactyl (The Land Before Time) R Red Claw the Tyrannosaurus Rex (The Land Before Time) They placed the bite force of the latter between 108,514 to 182,201 newtons (24,395 to 40,960 lbf) in a posterior bite, compared to the 18,216 newtons (4,095 lbf) bite force for the largest confirmed great white shark, and 7,400 newtons (1,700 lbf) for the placoderm fish Dunkleosteus. 'big, mighty' and ὀδούς (odoús), "tooth". It is now considered a junior synonym of Carcharocles. 12 years ago, before I lived in the sunshine state, before I became a fossil-hunting tour guide, I called the Florida Museum of Natural History vertebrate paleontology dept. This build is common in other large aquatic animals, such as whales, tuna, and other sharks, in order to reduce drag while swimming. Juveniles inhabited warm coastal waters and fed on fish and small whales. He first appears when Littlefoot, Petrie, Cera, Ducky and Spike are riding a log across the Big Water to try to get back to the shore on the mainland. [33] Nursery sites were identified in the Gatún Formation of Panama, the Calvert Formation of Maryland, Banco de Concepción in the Canary Islands,[82] and the Bone Valley Formation of Florida. It is believed to be an evolutionary dead-end and unrelated to the Carcharocles sharks by authors who reject that model.[28]:70. Guido (a.k.a. Petrie tries to paddle as fast as he can, but then he gets tired, and turns around. [79], Sharks often employ complex hunting strategies to engage large prey animals. The largest fluctuation of sea levels in the Cenozoic era occurred in the Plio-Pleistocene, between around 5 million to 12 thousand years ago, due to the expansion of glaciers at the poles, which negatively impacted coastal environments, and may have contributed to its extinction along with those of several other marine megafaunal species. He was advertised as the main antagonist, but this was the plot to be outranked by the final but general main villain. As the shark preferred warmer waters, it is thought that oceanic cooling associated with the onset of the ice ages, coupled with the lowering of sea levels and resulting loss of suitable nursery areas, may have also contributed to its decline. Edit source History Talk (0) Comments Share. It includes both major and minor antagonists listed with each film and television series. [27], Megalodon is now considered to be a member of the family Otodontidae, genus Otodus, as opposed to its previous classification into Lamnidae, genus Carcharodon. [21]:4, There was one apparent description of the shark in 1881 classifying it as Selache manzonii. The animal faced competition from whale-eating cetaceans, such as Livyatan and other macroraptorial sperm whales and possibly smaller ancestral killer whales. chubutensis. [84][85], The Earth experienced a number of changes during the time period megalodon existed which affected marine life. megalodon. [12][28][50], In 2002, shark researcher Clifford Jeremiah proposed that total length was proportional to the root width of an upper anterior tooth. The great white shark is more closely related to the mako shark (Isurus spp. [100] Some stories, such as Jim Shepard's Tedford and the Megalodon, portray a rediscovery of the shark. [76], Megalodon may have subjected contemporaneous white sharks to competitive exclusion, as the fossil records indicate that other shark species avoided regions it inhabited by mainly keeping to the colder waters of the time. [53], The coprolite remains of megalodon are spiral-shaped, indicating that the shark may have had a spiral valve, a corkscrew-shaped portion of the lower intestines, similar to extant lamniform sharks. Its distribution during the Miocene and Pliocene did not correlate with warming and cooling trends; while abundance and distribution declined during the Pliocene, megalodon did show a capacity to inhabit colder latitudes. [68][70] Fossil evidence indicates a correlation between megalodon and the emergence and diversification of cetaceans and other marine mammals. She lands in the water, and then the shark rises above her, and shows off his teeth. [104] Later, in August 2013, the Discovery Channel opened its annual Shark Week series with another film for television, Megalodon: The Monster Shark Lives,[105] a controversial docufiction about the creature that presented alleged evidence in order to suggest that megalodon was still alive. [97] Three individual megalodon, two adults and one juvenile, were portrayed in BBC's 2003 TV documentary series Sea Monsters, where it is defined as a "hazard" of the era. While the earliest megalodon remains have been reported from the Late Oligocene, around 28 million years ago (mya), there is disagreement as to when it appeared, with dates ranging to as young as 16 mya. [33][52], In 2019, Shimada revisited the size of megalodon and discouraged using non-anterior teeth for estimations, noting that the exact position of isolated non-anterior teeth is difficult to identify. Other species may have filled this niche in the Pliocene,[68][72] such as the fossil killer whale Orcinus citoniensis which may have been a pack predator and targeted prey larger than itself,[29][73][74][75] but this inference is disputed,[27] and it was probably a generalist predator rather than a marine mammal specialist. The shark's vertebrae may have gotten much bigger, and scrutiny of the specimen revealed that it had a higher vertebral count than specimens of any known shark, possibly over 200 centra; only the great white approached it. Heritage Auctions/Shutterstock.com. Fossil remains of some small cetaceans, for example cetotheres, suggest that they were rammed with great force from below before being killed and eaten, based on compression fractures. They are Fast Biters, a term used by the characters for dromaeosaurs, popularly known as raptors. Thats because sharks have skeletal structures made out of cartilage and not bone. Megalodon's intermediate tooth technically appears to be an upper anterior and is termed as "A3" because it is fairly symmetrical and does not point mesially (side of the tooth toward the midline of the jaws where the left and right jaws meet). [10][28]:78 It has been found at latitudes up to 55° N; its inferred tolerated temperature range was 1–24 °C (34–75 °F). [21]:iv It is possible that large megalodon individuals had jaws spanning roughly 2 meters (6.6 ft) across. [99] Several films depict megalodon, such as Shark Attack 3: Megalodon and the Mega Shark series (for instance Mega Shark Versus Giant Octopus and Mega Shark Versus Crocosaurus). This is unlikely since the sand tiger shark is a carangiform swimmer which requires faster movement of the tail for propulsion through the water than the great white shark, a thunniform swimmer. A dragon (or wyvern) appears in the episode, "The Spooky Nighttime Adventure", during a dream sequence. [81] Megalodon apparently further refined its hunting strategies to cope with these large whales. Geological events changed currents and precipitation; among these were the closure of the Central American Seaway and changes in the Tethys Ocean, contributing to the cooling of the oceans. [65] Additionally, a marine megafauna extinction during the Pliocene was discovered to have eliminated 36% of all large marine species including 55% of marine mammals, 35% of seabirds, 9% of sharks, and 43% of sea turtles. [4] The discovery of fossils assigned to the genus Megalolamna in 2016 led to a re-evaluation of Otodus, which concluded that it is paraphyletic, that is, it consists of a last common ancestor but it does not include all of its descendants. Cartilage doesnt hold up as well as bone, which is why there isnt a lot of fossil evidence of this prehistoric shark. [28]:64–65, Some fossil vertebrae have been found. This program received criticism for being completely fictional; for example, all of the supposed scientists depicted were paid actors. Littlefoot's grandfather is dreadfully ill and a golden flower is the only hope to cure him, but it lies within the land of the Mists so Littlefoot and [12][56], Megalodon is represented in the fossil record by teeth, vertebral centra, and coprolites. [28]:67[59] It most commonly occurred in subtropical to temperate latitudes. [72] The largest macropredatory sperm whales such as Livyatan are best known from the Miocene, but persisted into the Pliocene,[93] while others, such as Hoplocetus and Scaldicetus, survived until the early Pleistocene. The proposed relationship is: total length in meters = − (0.096) × [UA maximum height (mm)]-(0.22). [28]:65, Megalodon had a cosmopolitan distribution;[10][52] its fossils have been excavated from many parts of the world, including Europe, Africa, the Americas, and Australia. Swarming Leaf Gobblers' defeat. Petrie is sent under the water back and forth by Spike trying to eat a leaf off the branch he was perched on, and the final time the Flyer goes under the water, he looks around. [28]:99, In 1994, marine biologists Patrick J. Schembri and Stephen Papson opined that O. megalodon may have approached a maximum of around 24 to 25 meters (79 to 82 ft) in total length. [30] The genus was proposed by D. S. Jordan and H. Hannibal in 1923 to contain C. auriculatus. [45] Many whale bones have been found with deep gashes most likely made by their teeth. Great white shark hunting strategies may be similar to how megalodon hunted its large prey. The series adapts the film series, but with a twist: a human girl named Aylene ends up transported to the world that Littlefoot, Cera, Petrie, Ducky, and Spike inhabit, and becomes good friends with them, going on numerous adventures with them. [43] In addition, a 2.7-by-3.4-meter (9 by 11 ft) megalodon jaw reconstruction developed by fossil hunter Vito Bertucci contains a tooth whose maximum height is reportedly over 18 centimeters (7 in). [28]:75 By the end of the Miocene, many species of mysticetes had gone extinct;[68] surviving species may have been faster swimmers and thus more elusive prey. Its genus placement is still debated, authors placing it in either Carcharocles, Megaselachus, Otodus, or Procarcharodon. [28]:75 Various excavations have revealed megalodon teeth lying close to the chewed remains of whales,[28]:75[29] and sometimes in direct association with them. [45][46], In 1973, John E. Randall, an ichthyologist, used the enamel height (the vertical distance of the blade from the base of the enamel portion of the tooth to its tip) to measure the length of the shark, yielding a maximum length of about 13 meters (43 ft). It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.5 to 7 meters (8.2 to 23 ft) in length and other prey smaller than itself, rather than large whales in the same size class as themselves. Steven Spielberg's studio Amblin Entertainment was interested in doing a film about dinosaurs, which were popular at the time, leading Spielberg, director Don Bluth, and producer George Lucas to develop the prehistoric setting and its cast. This is very different from similarly sized modern killer whales that live to 65 years, suggesting that unlike the latter, which are apex predators, these physeteroids were subject to predation from larger species such as megalodon or Livyatan. Pterodactylus and Pterodactylus Kids' despair & defeat. [12] Their teeth were thick and robust, built for grabbing prey and breaking bone. [22], While the earliest megalodon remains have been reported from the Late Oligocene, around 28 million years ago (mya),[24][25] there is disagreement as to when it appeared, with dates ranging to as young as 16 mya. [28]:63–65 Another partially preserved vertebral column of a megalodon was excavated from the Gram Formation in Denmark in 1983, which comprises 20 vertebral centra, with the centra ranging from 100 millimeters (4 in) to 230 millimeters (9 in) in diameter. The fossil record indicates that it had a cosmopolitan distribution. Shimada stated that the maximum total length estimates, based on upper anterior teeth that are available in museums, are 14.2 and 15.3 meters (47 and 50 ft), depending on the estimation method used. It was probably one of the most powerful predators to have existed. The shark is shown going back underwater in the background. In the 1980s, megalodon was assigned to Carcharocles. Its scientific name is Carcharocles megalodon.It lived from the early Miocene to the Pliocene epochs, 23 to 3.6 million years ago (mya).It is not closely related to the present-day great white shark.. Megalodon had teeth, which are among the largest ever found, over 7 inches (18 cm) long. Megalodon Shark sighted in 1933, is perhaps the most credible. Megalodon (Otodus megalodon),[6][7][8] meaning "big tooth", is an extinct species of shark that lived approximately 23 to 3.6 million years ago (mya), during the Early Miocene to the Pliocene. Based on Tarlo's hypothesis, this specimen would be around 34 ft long. A cooling trend starting in the Oligocene 35 mya ultimately led to glaciation at the poles. [17] The specific name megalodon translates to "big tooth", from Ancient Greek: μέγας, romanized: (mégas), lit. It harasses the young Threehorn, blasting fire at her and chasing her. This is the first film in the series to be directed by Grosvenor, as well as the first film in which Anndi McAfee voices Cera, Aria Noelle Curzon voices Ducky, and Miriam Flynn voices Grandma Longneck. The overall modal length has been estimated at 10.5 meters (34 ft), with the length distribution skewed towards larger individuals, suggesting an ecological or competitive advantage for larger body size. To estimate the maximum size of Liopleurodon has been a controversial subject. Jeremiah pointed out that the jaw perimeter of a shark is directly proportional to its total length, with the width of the roots of the largest teeth being a tool for estimating jaw perimeter. This is the only major non-reptilian sharptooth to appear in the films, as sharks are fish. [28]:74–75, An exceptional case in the fossil record suggests that juvenile megalodon may have occasionally attacked much larger balaenopterid whales. [9] It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). Another model of the evolution of Carcharocles, proposed in 2001 by paleontologist Michael Benton, is that the three other species are actually a single species of shark that gradually changed over time between the Paleocene and the Pliocene, making it a chronospecies. A different story ] Meanwhile, juveniles likely had a blockier and megalodon land before time. On the other is purple in color for grabbing prey and breaking bone and H. Hannibal 1923.
