40 Fun Facts About Megalodon

Megalodon fossils are nearly all teeth because a shark's skeleton is made of what instead of bone?

Cartilage rarely fossilizes, so no complete megalodon skeleton has ever been found. That is why its true shape and size are still argued over.

Which TV network was criticized in 2013 for a fake documentary claiming megalodon still lives?

Discovery Channel opened Shark Week with the show, which was accused of passing off actors as scientists. It still drew 4.8 million viewers, a Shark Week record at the time.

A 2020 study suggested megalodon grew so huge partly because its unborn pups did what in the womb?

The biggest embryos ate their siblings, the theory goes, so each surviving pup grew larger. Mothers then had to be bigger still to carry them.

Which US state on Chesapeake Bay became the first to name a state shark, choosing megalodon?

Maryland made megalodon its state shark in 2026, and the animal's fossil teeth have turned up in at least seven of its counties.

Medieval nobles wore megalodon teeth as amulets and dipped them in drinks to guard against what?

Poison was the fear: nobles had the fossil teeth set into amulets and tableware, believing a touch would cleanse a tainted drink.

Megalodon teeth have turned up on every continent except which one, a sign of how widely it roamed?

Antarctica is the lone gap on the map. Megalodon favored tropical and subtropical seas, and its teeth are common finds off the US east coast and Morocco.

Which action star plays Jonas Taylor, a rescue diver battling a megalodon, in 'The Meg'?

Jason Statham really was a diver: before acting he was on Great Britain's national diving team and competed at the 1990 Commonwealth Games.

Megalodon had the largest teeth of any known shark, with the biggest measuring roughly how long?

About 7 inches is the record, measured along the tooth's slanted edge. A great white's teeth are usually less than a third of that.

The name megalodon, coined in the 1830s, combines words for 'big' and 'tooth' from which language?

Greek megalos (big) and odon (tooth) give the shark its name. It fits: teeth are nearly all that survives of the animal.

Chemical clues in megalodon teeth suggest the shark was partly what, unlike most fish?

Warm-blooded bodies burn far more fuel, which may have doomed megalodon: the extinction that claimed it hit heat-generating sea animals hardest.

Megalodon is long extinct: fossil evidence suggests the last ones died out roughly how long ago?

About 3.6 million years ago the fossil trail stops. Supposedly younger teeth, once used to argue the shark lived on, are now judged unreliable.

Before megalodon teeth were known to be fossils, Europeans called them glossopetrae, meaning what?

Tongue stones were believed to be the petrified tongues of snakes or dragons. The big triangular fossils do look the part.

Fossil whale bones suggest megalodon, unlike belly-biting great whites, bit toward which organs?

Heart and lungs sit behind the rib cage, so megalodon's thick teeth were built to punch through bone. Some whale ribs still carry the gashes.

In the film 'The Meg', the megalodon escapes from a hidden realm beneath which real Pacific feature?

Mariana Trench hides a deeper world in the film, sealed beneath a cloud of hydrogen sulfide until explorers break through it.

Fossil sites full of unusually small megalodon teeth, such as one in Spain, are thought to be what?

Nursery areas in shallow coastal water gave pups plenty of food and shelter from predators. Falling sea levels may later have erased many, one suspect in the extinction.

Megalodon's teeth resemble a great white's, a likeness most scientists now put down to what?

Convergent evolution gave two distant relatives similar serrated teeth. Megalodon's line had split from the great white's back in the age of dinosaurs.

Which author's 1997 novel 'Meg' launched the modern craze for tales of megalodon surviving today?

Steve Alten subtitled it 'A Novel of Deep Terror' and followed it with a string of sequels. Hollywood needed two decades to get the film version made.

Scientists aged one megalodon at 46 by counting growth bands, like tree rings, in which fossils?

Vertebrae from a fossil spine found in Belgium showed 46 yearly bands, and the same growth curve hints that megalodon could live for around a century.

Experts say megalodon could not be hiding in the deep ocean today because the water is too what?

Cold, food-poor depths would not suit a shark of tropical coasts. A living megalodon would also leave bitten whales and fresh teeth for us to find.

On which Mediterranean island were megalodon teeth tied to a legend of the shipwrecked Saint Paul?

Malta's rocks hold the teeth in large numbers. Legend says Saint Paul, bitten by a viper on arrival, stripped the island's snakes of their venom.

Roman folklore held that megalodon teeth, then a mystery, fell from the sky during which events?

Lunar eclipses got the blame from the Roman writer who left the oldest known record of fossil shark teeth, nearly 2,000 years ago.

Which Danish anatomist argued megalodon fossils were shark teeth after dissecting a shark's head?

Nicolas Steno was sent the head of a huge shark caught off Livorno in 1666, on the orders of the Grand Duke of Tuscany. He later became a Catholic bishop.

Which extinct sperm whale, named partly for Moby-Dick's author, competed with megalodon for prey?

Livyatan had teeth over a foot long, the largest biting teeth of any known animal apart from tusks. Its fossils were first found in the desert of Peru.

Believers in a living megalodon often cite which deep-water species, unknown to science until 1976?

The first megamouth shark turned up tangled in a US Navy ship's sea anchor off Hawaii. Megalodon was a hunter of coastal waters and would be far harder to miss.

Megalodon teeth, often found in its coastal rivers, are the state fossil of which US state?

North Carolina added the teeth to its state symbols in 2013, the same year it named an official frog, marsupial and salamander.

Megalodon coprolites, or fossil droppings, have which shape, a clue to the layout of its gut?

Spiral droppings point to a corkscrew-shaped valve in the lower intestine, a feature megalodon shared with living mackerel sharks.

In a 2009 B-movie from The Asylum, a megalodon thawed from a glacier battles which sea monster?

Giant octopus and megalodon thaw from the same glacier in 'Mega Shark Versus Giant Octopus', a film in which the shark also bites a chunk out of the Golden Gate Bridge.

In which pirate game from the studio Rare can a megalodon or the kraken attack a crew's ship at sea?

Sea of Thieves sends two monsters after sailing crews, the megalodon and the kraken, alongside storms, skeleton ships and ghost fleets.

A 2025 study argued megalodon was slimmer than a great white, built more like which living species?

Lemon shark proportions would be more efficient in the water: scale a stocky great white up to megalodon size and it would struggle to swim.

A 2021 study of megalodon tooth widths put the shark's maximum body length at roughly what?

About 66 feet, or 20 meters, is more than three times the length of a large great white. Newer work, assuming a slimmer body, stretches the figure toward 80 feet.

Which naturalist, later a pioneer of glacier science, gave megalodon its scientific name?

Louis Agassiz named it in his five-volume study of fossil fish. He first grouped it with the sand tiger shark, then moved it beside the great white.

Megalodon teeth dredged up by which 1870s British ship later fueled claims of recent survival?

HMS Challenger's teeth looked fresh and were once dated to as little as 11,000 years old. In fact a mineral crust had slowed their decay and kept them white.

Miocene seas held more than 20 genera of baleen whale, against six today. That abundance is thought to have supported a super-predator of megalodon's size.

Bashford Dean's 1909 megalodon jaw model, later judged far too big, first went on show where?
