otodus obliquus facts

there is literally nothing but teeth to fossilize. serrations forming on 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. [28]:57 As with all sharks, the skeleton of megalodon was formed of cartilage rather than bone; consequently most fossil specimens are poorly preserved. [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.   Quaternary

It is now considered a junior synonym of Carcharocles. [12][56], Megalodon is represented in the fossil record by teeth, vertebral centra, and coprolites. Great white shark hunting strategies may be similar to how megalodon hunted its large prey. They think a split occurred after Cretolamna appendiculata into two divisions: Otodus obliquus and Paleocarcharodon orientalis. [18][19] The teeth of megalodon are morphologically similar to those of the great white shark (Carcharodon carcharias), and on the basis of this observation, Agassiz assigned megalodon to the genus Carcharodon.

[6][31] In this model, O. obliquus evolved into O. aksuaticus, which evolved into C. auriculatus, and then into C. angustidens, and then into C. chubutensis, and then finally into C. megalodon. [10] This is consistent with evidence that it was a mesotherm. Otodus had a cosmopolitan distribution, as fossils have been excavated from Africa, Asia, Europe, North America, and Japan. [28]:77 However, an analysis of the distribution of megalodon over time suggests that temperature change did not play a direct role in its extinction. [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. One of the reasons the Megalodon is extinct may be that it was out-competed by its cousins, other Otodus obliquus descendants. 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.

They do not suggest any trend of changing body size with absolute latitude, or of change in size over time (although the Carcharocles lineage in general is thought to display a trend of increasing size over time).

[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.
[42], Marine mammals attained their greatest diversity during the Miocene,[28]:71 such as with baleen whales with over 20 recognized Miocene genera in comparison to only six extant genera. their edges. [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] Many whale bones have been found with deep gashes most likely made by their teeth.

[28]:63, In 2008, a team of scientists led by S. Wroe conducted an experiment to determine the bite force of the great white shark, using a 2.5-meter (8.2 ft) long specimen, and then isometrically scaled the results for its maximum size and the conservative minimum and maximum body mass of megalodon. [45] Furthermore, attack patterns could differ for prey of different sizes. Vessels of the Great White are large and in groups.

The teeth of this shark are large with triangular crown, smooth cutting edges, and visible cusps on the roots. [7], The most common fossils of megalodon are its teeth. There are a few who will mention the [97] The shark appears in the 2017 videogame Ark: Survival Evolved. The largest predatory shark that ever lived, the Megalodon, is thought to be one of the Otodus obliquus's descendants. Numerous fossilized flipper bones and tail vertebrae of large whales from the Pliocene have been found with megalodon bite marks, which suggests that megalodon would immobilize a large whale before killing and feeding on it.

[80] Megalodon bite marks on whale fossils suggests that it employed different hunting strategies against large prey than the great white shark. [1][16] English paleontologist Edward Charlesworth in his 1837 paper used the name Carcharias megalodon, while citing Agassiz as the author, indicating that Agassiz described the species prior to 1843. [79], Sharks often employ complex hunting strategies to engage large prey animals. [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.

[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.

the Bartonian of the Eocene. Unlike the great white, which attacks prey from the soft underside, megalodon probably used its strong jaws to break through the chest cavity and puncture the heart and lungs of its prey. [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. [61] The shark was an opportunist and piscivorous, and it would have also gone after smaller fish and other sharks. Otodus is an extinct mackerel shark which lived during the Paleocene and Eocene epochs, approximately 60 to 45 million years ago. Otodus is an extinct mackerel shark which lived during the Paleocene and Eocene epochs, approximately 60 to 45 million years ago. that one can’t ignore the root depth and serration size. 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. disappears from the fossil record in the mid Eocene when the Name: Otodus. A cooling trend starting in the Oligocene 35 mya ultimately led to glaciation at the poles. Megalodon may have moved between coastal and oceanic waters, particularly in different stages of its life cycle.
