During Ancient Times, Giant Sharks Roamed The Seas, Feasting On Huge Prey
A Giant
Shark roamed the oceans millions of years ago, and scientists
believe it would have been able to devour a killer whale in just five bites.
Compared to their ancient
cousins, today’s sharks are nothing. It would have taken just five bites for a
giant shark to devour a creature the size of a killer whale millions of years
ago, according to new research. Researchers created a 3D model of the megalodon
– one of the biggest predatory fish ever – using fossil evidence published
Wednesday.
The Size Of Those Sharks Is Approximately 16 Meters
According to a study published in
Science Advances, the megalodon measured about 50 feet (16 meters) from nose to
tail. Compared to today’s great white sharks, that’s about twice the size. As a
result of its gaping jaw, the megalodon was able to feed on other large
animals. According to the researchers, if it filled its massive stomach, it
could roam the oceans for months at a time.
Moreover, the megalodon had
excellent swimming abilities: its average cruising speed was faster than sharks
today, and it could have easily migrated across oceans. According to co-author
John Hutchinson of the Royal Veterinary College in England, it would be a
superpredator whose sole purpose would be to dominate its ecosystem. Until now,
scientists have been unable to get a clear picture of the megalodon, said study
author Catalina Pimiento, a paleobiologist at the University of Zurich and
Swansea University.
Megalodon Would Have Weighed About 10 Elephants
Physicists believe that the
skeleton is composed of soft cartilage that does not fossilize well. The
scientists used the few fossils available, including vertebrae from a Belgian
museum that have been preserved since the 1860s. Hutchinson said researchers
brought in a jaw’s worth of megalodon teeth that were as large as human fists.
The rest of the information was provided by scanning of great white sharks of
today. Researchers calculated that the megalodon would have weighed about 70
tons, or about 10 elephants.
Megalodons Could Open Their Jaws Nearly 6 Feet Wide
Megalodons were capable of opening their jaws up to almost 6 feet (2 meters), which could be used as lunch meat by other high-level predators, according to Pimiento. It is estimated that megalodons lived 23 million to 2.6 million years ago. Paleontologist Michael Gottfried, who was not involved in the study, said megalodon fossils are rare, so these kinds of models require a leap of imagination. According to him, the findings of the study are reasonable in light of what is known about giant sharks
