Super Fossilien Jagd, aber wo bleibt mein Megaladon Zahn? - Florida USA VLog 12 Teil 3 (Vollversion)Some fossil vertebrae have been found. The most notable example is a partially preserved vertebral column of a single specimen, excavated in the Antwerp Basin , Belgium, in It comprises vertebral centra , with the centra ranging from 55 millimeters 2.
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 centra; only the great white approached it.
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.
Gottfried and colleagues reconstructed the entire skeleton of megalodon, which was later put on display at the Calvert Marine Museum in the United States and the Iziko South African Museum.
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.
Megalodon inhabited a wide range of marine environments i. Adult megalodon were not abundant in shallow water environments, and mostly inhabited offshore areas.
Megalodon may have moved between coastal and oceanic waters, particularly in different stages of its life cycle.
Fossil remains show a trend for specimens to be larger on average in the southern hemisphere than in the northern, with mean lengths of 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.
The overall modal length has been estimated at Megalodon had a global distribution and fossils of the shark have been found in many places around the world, bordering all oceans of the Neogene.
Though sharks are generally opportunistic feeders, megalodon's great size, high-speed swimming capability, and powerful jaws, coupled with an impressive feeding apparatus, made it an apex predator capable of consuming a broad spectrum of animals.
It was probably one of the most powerful predators to have existed. That is to say it was higher up in the food chain. Fossil evidence indicates that megalodon preyed upon many cetacean species, such as dolphins, small whales, cetotheres , squalodontids shark toothed dolphins , sperm whales , bowhead whales , and rorquals.
The feeding ecology of megalodon appears to have varied with age and between sites, like the modern great white. It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.
Megalodon faced a highly competitive environment. Such preferences may have developed shortly after they appeared in the Oligocene. 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.
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.
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.
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.
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.
Sharks often employ complex hunting strategies to engage large prey animals. Great white shark hunting strategies may be similar to how megalodon hunted its large prey.
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.
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.
During the Pliocene, larger cetaceans appeared. 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.
Megalodon, like contemporaneous sharks, made use of nursery areas to birth their young in, specifically warm-water coastal environments with large amounts of food and protection from predators.
Given that all extant lamniform sharks give birth to live young, this is believed to have been true of megalodon also. An exceptional case in the fossil record suggests that juvenile megalodon may have occasionally attacked much larger balaenopterid whales.
The Earth experienced a number of changes during the time period megalodon existed which affected marine life. 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.
The stalling of the Gulf Stream prevented nutrient-rich water from reaching major marine ecosystems, which may have negatively affected its food sources.
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.
As its range did not apparently extend into colder waters, megalodon may not have been able to retain a significant amount of metabolic heat, so its range was restricted to shrinking warmer waters.
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.
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.
The extinction was selective for endotherms and mesotherms relative to poikilotherms , implying causation by a decreased food supply [86] and thus consistent with megalodon being mesothermic.
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.
These may have occupied a niche similar to that of orcas before eventually being replaced by them. The extinction of megalodon set the stage for further changes in marine communities.
The average body size of baleen whales increased significantly after its disappearance, although possibly due to other, climate-related, causes.
Megalodon may have simply become coextinct with smaller whale species, such as Piscobalaena nana. 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.
This program received criticism for being completely fictional; for example, all of the supposed scientists depicted were paid actors.
In , Discovery re-aired The Monster Shark Lives , along with a new one-hour program, Megalodon: The New Evidence , and an additional fictionalized program entitled Shark of Darkness: Wrath of Submarine , resulting in further backlash from media sources and the scientific community.
Fossil megalodon teeth can vary in color from off-white to dark browns and greys, and some fossil teeth may have been redeposited into a younger stratum.
The claims that megalodon could remain elusive in the depths, similar to the megamouth shark which was discovered in , are unlikely as the shark lived in warm coastal waters and probably could not survive in the cold and nutrient-poor deep sea environment.
