The shark-eating megalodon remains the most ferocious sea monster ever with gigantic teeth

The 20 meter long Otodus Megalodon is the deadliest shark to ever live, according to a new scientific study.

Megatooth sharks, including the fearsome megalodon, have long been considered the prehistoric rulers of the world’s oceans, but research on their gnashers claims to confirm this.

Examination of thousands of shark teeth proved the megalodon to be the ultimate apex predator, surpassing everything else on record as it feasted on other predators.

Scientists say the material found on their giant teeth earned them the highest “trophic level,” otherwise known as the top of its food chain, as much as possible.

The study’s first author, Dr Emma Kast, also addresses fears and conspiracy theories that the extinct apex predator is still alive and preying on the likes of great white sharks.

The report “Cenozoic megatooth sharks occupied extremely high trophic positions” was published in the journal Scientists progressWednesday, June 22 and got fans of the phenomenal sea monster excited.

Research by scientists such as those at Princeton University has proven that being the largest creature lurking underwater really does mean, in the case of the megalodon, being the top dog in the food chain.

Dr Emma said in a statement: “Megalodon and other megatooth sharks were truly huge carnivores that ate other predators, and Meg became extinct only a few million years ago.”

Like a third of all large marine animals, the megalodon died out 3.6 million years ago at the end of the Pliocene, when the planet entered a phase of global cooling.

Yet thanks to images such as images of a great deep-sea shark and another scarred shark, it’s been debated that the megalodon is alive and well but keeping a very, very low profile.

Danny Sigman, another co-author of the study, added, however, “If Megalodon existed in the modern ocean, it would completely change the way humans interact with the marine environment.”

To determine the megalodon’s place in the food chain, scientists examined the nitrogen in recovered fossil teeth.

The study’s introduction reads: “The stable carbon, oxygen, and strontium isotope composition of fossil bones and tooth enamel is used to investigate food web primary producers; to distinguish between terrestrial, aquatic and marine habitats; and to reconstruct physiology.”

When it comes to examining the predator’s place in the food chain, the more nitrogen-15 an organism has, the higher its trophic level, which had not yet been measured from their fossils.

The study considered the smaller ancestors of megalodon that evolved into gigantism.

As a result of the research, scientists say megatooth sharks most likely hunted around the world at the top of a global marine food chain, which was potentially a few steps longer than anything seen today.

Emma added: ‘I would like to find a museum or other archive with a snapshot of an ecosystem – a collection of different types of fossils from a time and place, forams near the very base of the network trophic, to the otoliths – inner ear bones – of different types of fish, to the teeth of marine mammals, as well as shark teeth.

“We could do the same nitrogen isotope analysis and piece together the whole history of an ancient ecosystem.”
