The 18.26 meter specimen was the largest of 3 (Another two megalodon skeletons were found in Peru). And according to the slant height of the teeth which is 18.6 cm (7.3 inches), it was larger then typical teeth found.

Which is the greatest ocean predator – the
orca or the great white shark? A shocking encounter off the Californian
coast reveals the answer.
When wildlife-watchers in a boat off the Farallon Islands witnessed
an orca attacking a great white shark, they were astonished by how
easily the fish was overpowered. However, much of the action took place
out of sight, under water. Scientists have pieced together the evidence
to construct the likely sequence of events that led to the shark’s
apparently timid demise.
From the eyewitness accounts, it was clear that the orca didn’t bump
into the great white by chance. It deliberately changed course to
intercept its victim. The shark appeared unaware that it was in danger.
Swimming at top speed, the orca took the shark by surprise, ramming
it hard on the flank. The massive impact stunned the shark, leaving it
momentarily confused and vulnerable.
With the shark dazed, the orca grasped it behind the head and turned
it upside- down. The shark panicked and its brain released calming
serotonin that sent it into a trance. This made it far easier for the
orca to drown its prey.
Soon the shark was dead and the orca could start tearing it apart.
CLASH OF THE TITANS:
ORCA Orcinus orca
SIZE: Adult male up to 9.5m; adult female up to 8.2m.
WEIGHT: Male up to 5,600kg; female up to 3,600kg.
TEETH: 40–52 large, conical, inward-curving teeth in upper and lower jaw.
MAX SPEED: Bursts of 50kmph when in pursuit of prey.
TYPICAL PREY: Mostly fish and squid; also seals, sealions and other marine mammals and seabirds. Consumes up to 200kg of food daily.
MAX PREY SIZE: Several records of orcas attacking and eating grey whale calves.
HUNTING TECHNIQUE: Often works in teams to corral fish or to distract prey to isolate or weaken it before delivering the killer blow.
SPECIAL SKILLS: Uses echolocation – a form of sonar – to detect shoals of fish under water.
DISTRIBUTION: Found in all of the world’s oceans, but most abundant in cooler waters at high latitudes.
GREAT WHITE SHARK Carcharodon carcharias
SIZE: 4–5.5m fully grown; occasionally over 6m. Females generally larger.
WEIGHT: Usually up to 1,000kg; rarely up to 2,200kg.
TEETH: 3,000 razor-sharp, triangular teeth arranged
in several rows that rotate towards the front of the mouth, replacing
broken ones as needed.
MAX SPEED: Often reaches 40kmph.
TYPICAL PREY: Mostly big fish, including tuna, rays
and other sharks; also seals, sealions, dolphins, turtles and
max prey size Sometimes attacks and kills smaller great whites
HUNTING TACTICS: Solitary, ambushes prey from below with a powerful surge.
SPECIAL SKILLS: Excellent sense of smell: can detect
a drop of blood in 100 litres of water. Electromagnetic sense picks up
the magnetic field produced by muscle activity in its prey.
DISTRIBUTION: Found almost worldwide, from the subtropics to cooler, temperate seas; some populations highly migratory.
DID YOU KNOW? Great white sharks will sometimes eat
whales but usually only after they're dead. There are numerous records
of sharks scavenging whale carcasses.

Forget about the satwater crocodile:
Mature male saltwater crocs can be 6 metres (20 ft) or more and weigh 1,300 kilograms (2,900 lb) or larger
Forget about Sarcosuchus, the 30 foot long prehistoric SuperCroc:
Forget about today’s white sharks:
Great White Sharks have exceeded 6 metres (20 ft) in length and 2,240 kilograms (4,938 lb)
Forget about the prehistoric shark C. megalodon:
Model of C. megalodon shark's head
Every diver's worst nightmare
Forget about the mighty T-Rex:
is probably still the king of bite of land animals who have lived,
although Deinosuchus, an extinct alligator, may have had a stronger bite
When it comes to the Bad Dude of Bites, no creature that ever lived can match the mighty pliosaur called Predator X:
Predator X attacking a plesiosaur
Thought to have a bite 11 times as strong as that of Tyrannosaurus rex, Predator X (a new kind of pliosaur) bit down with a calculated power of over 15 tons or 33,000 pounds of bite force.
By comparison, today’s alligators, which have the strongest known bite
of any animal, crush down with “only” 2,500 pounds of bite force.
Predator X was at least 50 feet long and would have weighed more than
Predator X (bottom) compared to a blue whale, the largest animal that's ever lived, and a modern orca, or killer whale
Surely, Predator X was the mightiest predator that ever lived—or was it?
A recent fossil discovery in Peru by paleontologists may mean the
mighty Predator X has been deposed from its throne—or at least, met its
match. The new contender is a prehistoric sperm whale that lived about
12 million years ago. The paleontologists that discovered it have named
it Leviathan melvillei, in honor of Herman Melville, author of Moby Dick. The jaws and teeth of this prehistoric sperm whale might have given even mad Captain Ahab pause:
Leviathan melvillei probably hunted baleen whales
Super Moby Dick
Leviathan melvillei, an ancestor of sperm whales, grew up to
60 feet long—comparable to today’s biggest sperm whales. What sets it
apart from today’s sperm whales is that its mouth was more like that of a
modern orca, or killer whale, with upper and lower teeth. The sperm whale only has lower teeth, which fit into sockets in the top of its mouth:
Sperm whales only have lower teeth which fit into upper sockets
The killer whale has both lower and upper teeth, but they do not interlock for shearing like the teeth of Leviathan melvillei do
The mouth of Leviathan melvillei had interlocking teeth that sheared past each others. Clearly, Leviathan melvillei’s teeth and jaws were designed to rip and tear huge chunks of flesh out of other whales and probably large sharks as well.
Consider this: Leviathan melvillei lived at the same time that C. megalodon
lived. Both were top predators. One can only imagine what a
confrontation between those two monsters was like! With such formidable
teeth, no doubt, whoever struck first was the victor.
Leviathan melvillei's teeth were 4 inches longer than this 10-inch T-rex tooth!
Leviathan melvillei’s tusk-like teeth were about 36 centimeters (14
inches) long, almost twice the length of modern sperm whales. In
comparison, the longest T-rex tooth measures about 27 centimeters, a
little over 10 inches from root to tip. It’s longer and bigger around
than Predator X’s 12 inch teeth. Imagine a tooth as long and big around
as a man’s forearm!
Scientists believe the typical prey of the Leviathan melvillei would have been baleen whales that were 20 to 25 feet in length. The jaws, teeth, and muscles of Leviathan melvillei would have needed to incredibly strong and powerful to withstand the stress of struggling prey of this size.
“This is a pretty exciting discovery,” says Erich Fitzgerald, a
vertebrate paleontologist at Museum Victoria in Melbourne, Australia. Leviathan represents “one thing we don’t have in the oceans today — a macropredator, a hypercarnivorous whale.”
So, who gets your vote for the top predator of all time? The super sperm whale, Leviathan melvillei? Or is Predator X still the king? In either case, these are the greatest jaws of all time.
A long time ago a strange creature appeared in China and horrified and ate men and animals. The fast and fierce creature was called 'nien' (or 'nian'), which sounds like the Chinese word for 'year'. Neither the fox nor the tiger could fight the 'nien' effectively and in despair the people asked the lion for help.

It's bite force was said to be huge.I haven't been keeping up-to-date recently but wasn't Ramphosuchus 50-60 feet and the largest prehistoric crocodilian ever lived, even if it was build like a Gharial, it would still be an immensely powerful animal.
