The Killer Shark: MEGALODON
There are more than 465 known species of sharks living in our oceans today. Sharks are an apex predator at or near the top of their marine food chains, and they regulate the populations of species below them.
Megalodon meaning "big tooth"is regarded as one of the largest and most powerful predators in vertebrate history,probably had a profound impact on the structure of marine communities.
#9 Fossil Misconception
The gigantic, triangular fossil teeth often found embedded in rocky formations were once believed to be the petrified tongues, or glossopetrae, of dragons and snakes.
This interpretation was corrected in 1667 by Danish naturalist Nicolaus Steno, who recognized them as shark teeth, and famously produced a depiction of a shark's head bearing such teeth.
#8 Oldest Fossil Found
Megalodon's skeleton was formed of cartilage rather than bone; this means that most fossil specimens are poorly preserved.
It's teeth have been excavated from regions far away from continental lands, such as the Mariana Trench in the Pacific Ocean.
#7 Giant Teeth
The most common fossils of megalodon are its gigantic teeth.
Diagnostic characteristics include: triangular shape, robust structure, large size,fine serrations,and visible V-shaped neck. Megalodon teeth can measure over 180 millimetres (7.1 in) in slant height or diagonal length, and are the largest of any known shark species.
#6 Eat Whatever Comes In Its Way
Megalodon employed even more effective hunting strategies against large prey than the great white shark.
The paleontological evidence suggests that megalodon would immobilize a large whale by ripping apart or biting off its locomotive structures before killing and feeding on it.Megalodon also displayed cannibalistic features and consumed other smaller Megalodons too.
#5 Nurturing Babies
Fossil evidence suggests that the preferred nursery sites of megalodon were warm water coastal environments, where threats were minor and food plentiful where they gave birth to live young.Their teeth alone measured 2 to 4 metres.
#4 Huge Size
Growing to an estimated length of over 50 feet (16 meters),resembled something out of a prehistoric nightmare and has no modern equivalents in terms of size.
,br> A great white shark is about the size of the clasper, or penis, of a male megalodon.
Several possible causes for its decline and eventual disappearance have been proposed.
Oceanic cooling and sea level drops
Decline in food supply
#2 Dicovery Of Fossils Worldwide
Its fossils have been excavated from many parts of the world, including Europe, Africa and both North and South America,as well as Puerto Rico,Cuba, Jamaica, the Canary Islands, Australia, New Zealand,Japan, Malta, the Grenadines and India.
#1 How Powerful
The most powerful bite of all time has been found — that of the prehistoric giant shark Megalodon. Fossil evidence suggests Megalodon made a living hunting and killing large whales by biting off their tails and flippers.
