The Rhedosaurus is a giant fictional dinosaur who serves as the antagonist of the 1953 American giant monster film The Beast from 20,000 Fathoms. It is based on a creature from the short story "The Fog Horn."

Name

According to Rhedosaurus creator Ray Harryhausen, the monster's name may have been devised by The Beast from 20,000 Fathoms producer Hal E. Chester or one of the film's writers. He went on to say that some people believe the first two letters of Rhedosaurus's name were inspired by his initials, R. H. The beast has also been nicknamed Herman, and is sometimes referred to as a "Rhedosaur."

Development

The concept of "The Fog Horn" and its accompanying dinosaur were inspired by a visit author Ray Bradbury made to Venice, California in 1949, where he heard the fog horn sound after having seen the "bones" of the Giant Dipper roller coaster, which had been demolished three years prior.

The producers of The Beast from 20,000 Fathoms, Jack Dietz and Hal E. Chester, were initially uncertain what kind of monster they desired for their film. Animator Ray Harryhausen and director Eugène Lourié made several sketches, including one of a giant octopus. Harryhausen did not wish for the beast to be a recognizable animal and instead wanted it to be a dinosaur, but not an Allosaurus or Brachiosaurus, as the film would likely be compared to The Lost World (1925). The final design of the Rhedosaurus featured in the film was considered to be scientifically inaccurate, with Lourié reportedly having to explain to the Museum of Natural History why they did not instead include a depiction of a real dinosaur such as the Tyrannosaurus rex. According to Variety, he told them, "We wanted a brand new monster who looks more frightening than the real thing".

Harryhausen created a clay model of the Rhedosaurus based on his sketches, but he and other staff members felt that it was "too kind, too babyish" and "dog-like". Thus, Harryhausen returned to his workshop to make a stronger, more terrifying version of the model. The new model was tested, but Harryhausen felt that it still wasn't right, creating a third and final version after discussion with Dietz and Chester. Parts of the completed model were later repurposed for the fire-breathing dragon in The 7th Voyage of Sinbad (1958). A five-second piece of stop-motion animation of the Rhedosaurus cut from the film appeared in the trailer for The Black Scorpion, released in 1957.

For Planet of Dinosaurs, Stephen A. Czerkas constructed a new, smaller model that was used to battle, and ultimately be killed by, a Tyrannosaurus rex. According to animator Jim Aupperle, "Stephen and I both place the Rhedosaurus among our top favorite of Ray's myriad monsters. We felt that by giving the great Beast a cameo in our film we were acknowledging the immense debt we both feel to Ray. We had to make the Rhedosaurus more of a baby size because one as large as the original would have made a meal of our Tyrannosaurus instead of the other way around." Harryhausen visited the set during filming.

Design

The creature from "The Fog Horn," upon which the Rhedosaurus is based, is said to have a 40-foot long neck, a body covered in crayfish and other sea life, and a tail that was only barely seen.

In The Beast from 20,000 Fathoms, the Rhedosaurus has a quadrupedal build, with a long tail and forelimbs noticeably longer than its hindlimbs. Its back is adorned with a single row of backward-facing spikes that continue from its scalp to its tail. Crocodilian scales line down its underside while bumpy, pebble-like scales cover the remainder of the body. Its snout is short with large nostrils and noticeable fangs.

In Planet of Dinosaurs, the Rhedosaurus has a slimmer skull and a slightly longer neck. Its skin is brown.

Origins

In The Beast from 20,000 Fathoms, the Rhedosaurus was the only surviving member of its species, buried beneath the ice in the Arctic for over 100 million years until it was reawakened by a nuclear bomb test in the modern day.

In Planet of Dinosaurs, the Rhedosaurus is an inhabitant of an alien planet identical to Earth in the Mesozoic era.

The Beast from 20,000 Fathoms

The Rhedosaurus in The Beast from 20,000 Fathoms

The United States conducted an atomic bomb test, known as "Operation Experiment", in the far north of the Arctic Circle. Shortly after the test was conducted, two men briefly noticed a 500-ton silhouette on the radar display and one of them informed Colonel Jack Evans. Tom Nesbitt and George Ritchie embarked on patrol at Post 18 around where the blast happened; Ritchie saw the creature and fell into a crevasse in shock. As soon as Nesbitt found him injured, the prehistoric monster created an avalanche from the glaciers above them. This trapped Ritchie in the crevasse, killing him. Nesbitt survived and was taken to a hospital in New York City, where he tried to convince Dr. Ingersoll that he truly saw a monster. Dr. Ingersoll and Evans disputed his claims. The latter informed Nesbitt that he went to the area afterward and saw no traces of the creature whatsoever.

Meanwhile, the dinosaur was heading toward the U.S., destroying a fishing boat near the Grand Banks. While still in the hospital ward, Nesbitt saw that the sole survivor reported this in a newspaper article. He went to a university's Department of Paleontology to meet Dr. Thurgood Elson, requesting that he start an expedition to search for the creature. However, Elson stated that he "can't support" his claim that an over 100-million-year-old prehistoric creature was awakened by the bomb and roams the sea. It was publicly announced that a second ship had been destroyed near Nova Scotia, Canada. The following day, Nesbitt returned to his office and received a visit from Elson's assistant, Dr. Lee Hunter, who had gathered illustrations of prehistoric creatures to help him identify what he saw in the Arctic. Both Hunter and a witness of the creature who was onboard one of the ships it sank to New York identified the same drawing to be the monster. Elson then explained that it must be a Rhedosaurus, the only known fossils of which were found in the Hudson cliffs of the Hudson River 150 miles from New York. Elson asked Evans to report any more Rhedosaurus sightings to him, Hunter, and Nesbitt.

On one stormy night, the Rhedosaurus destroyed a lighthouse off the coast of Maine, killing two men inside. Soon after, Evan's friend Captain Phillip Jackson reported to the group that several buildings were destroyed by the creature along the Massachusetts coastline. A farmer was crushed to death. Elson then listed all of the sightings of the dinosaur, stating that it has followed the Arctic Current to the United States and that it is likely heading toward the canyon near New York where the only known fossils of its kind were found. Elson suggested that the Rhedosaurus should be captured, and desired to see it in person to determine what method to use. He asked Jackson for a diving bell to see the beast under a 150-mile undersea canyon, where it ultimately killed him.

The Rhedosaurus emerged in New York Harbor and wandered into downtown New York. Civilians fled in fear after it ate a policeman and destroyed cars in its path. The New York City Police Department dispatched their entire force to contain the Rhedosaurus and a group of officers fired rounds at the creature without effect. The creature then burst through a building and killed civilians behind it. Later that day, it was reported that the beast caused $300 million in damage, killed at least 180 civilians, and injured 1500 more.

That night, the United States Army prepared for the beast, setting up machine guns on rooftops and an electrified fence. The Rhedosaurus soon appeared and was shot in the neck by a bazooka while unsuccessfully trying to strike the fence; it strolled away and soldiers found blood from the creature, indicating that the bazooka successfully harmed it. Several troops followed the Rhedosaurus's blood trail when suddenly some collapsed; doctors soon discovered that they have been stricken by a deadly ancient disease it carried that was transmitted to them by its blood.

Meanwhile, the Rhedosaurus had returned to New York Bay, briefly remaining there before coming ashore on Manhattan Beach. Nesbitt told Evans that the only way to defeat the beast was to shoot a radionuclide into its tissue. As the Rhedosaurus ruined the rollercoaster on Coney Island, the army prepared the radioactive isotope. Nesbitt and sniper Corporal Stone travel to a high section of the rollercoaster and the latter fired the only radionuclide into the wound on its neck, both fatally wounding the beast and neutralizing the disease. As the Rhedosaurus succumbed to the isotope, a fire it started by destroying the machinery of a roller coaster spread across the island. The Rhedosaurus burst free of the burning coaster and roared out defiantly, before finally collapsing to the ground, dead.

Planet of Dinosaurs

The Rhedosaurus in Planet of Dinosaurs

As a Tyrannosaurus rex began menacing Captain Lee's crew, Lee and Jim broke into an argument over who should be in charge of crafting a plan to kill it. To prove his resolve, Lee baited the Tyrannosaurus into chasing him away from the camp when the trap preparations were not yet ready. As he continued to run, he took shelter under a ledge, above which a car-sized Rhedosaurus appeared. It hissed at Lee but did not chase him as he continued running. The pursuing Tyrannosaurus came upon the Rhedosaurus and roared at it. The Rhedosaurus roared back, prompting the Tyrannosaurus to lunge at it and bite it on the shoulder, carrying it in the air for several seconds as the Rhedosaurus struggled and tried to fight back. The conflict was ended when the Tyrannosaurus set the Rhedosaurus on the ground and quickly bit into its head, crushing its skull and killing it before carrying the body back to its lair to feed on it, giving Lee enough time to return to his crew and plan the counterattack against the dinosaur.

Abilities

Contaminated blood

The Rhedosaurus's blood is host to a prehistoric virus. As the human immune system has no basis to defend against it, anyone exposed to it becomes fatally ill, which forbids the use of heavy ordinance.

Physical abilities

The Rhedosaurus primarily relies on its sheer bulk and powerful limbs during combat, shown when it topples over a lighthouse and crushes a car like it was an insect underneath its metaphorical boot. Its jaws were able to kill and eat a human in one bite as well.

Durability

The Rhedosaurus's scales were thick enough to be unharmed by small arms fire, though heavier munitions were able to wound it sufficiently enough to be able to kill it.

Short stories

• "The Fog Horn" (1951)

"The Fog Horn"

In the short story "The Fog Horn", which was adapted as The Beast from 20,000 Fathoms, a large, dinosaur-like creature with a longer neck, but otherwise similar to the Rhedosaurus, appears from the depths, attracted to a lighthouse and the sound of its fog horn. The creature first appeared circling the lighthouse, but left soon after. Exactly one year later, the creature reappeared and started calling out to the lighthouse. When the fog horn stopped calling back, the creature attacked and destroyed the lighthouse, then went back into the ocean, never to return.

Comics

• Ray Bradbury Comics #3 (1993)

"The Fog Horn"

One night per year, a mysterious sea beast came to the stone tower housing the fog light and fog horn operated by a man named McDunn. McDunn's assistant Johnny could not believe his eyes as the creature, unchanged for millions of years, arose on its 40-foot neck and roared at the tower. The fog horn roared back, and the beast returned the favor, while McDunn lamented the fact that while it was living its life the same as it ever did, the world it inhabited had changed around it in ways it could not possibly understand. He imagined that all year long it waited, and spent months surfacing to avoid damaging itself before swimming for days to get to the tower just to hear a familiar roar like its own. After the two exchanged another volley of bellowing, McDunn switched off the horn just to see what might happen. The beast stopped for a moment, and growled at the tower. Angry with the lack of reply, it reared up and slammed into the tower. McDunn turned the horn back on, but it was too late. It bit at the light, shattering its glass casing, and leaned on the tower until it toppled over and the horn stopped sounding. Anguished at the realization that it had lost its only companion, the beast cried out intermittently all night, but was gone in the morning. McDunn told no one of what happened, blaming the damage on the waves, and the next year, Johnny came to visit McDunn in the new lighthouse erected on the same spot, but the creature never returned.

Roar

In The Beast from 20,000 Fathoms, the Rhedosaurus's roars are derived from the sound effects of a wild horse used in the 1952 film The Lion and the Horse. The Rhedosaurus's main roars were reused for Harryhausen's dinosaurs in The Animal World (1956), including the Triceratops.

In the short story "The Fog Horn", its roar is said to be like the sound of a lighthouse's fog horn.

Trivia

• The Rhedosaurus, along with King Kong, was one of the main inspirations for Godzilla. During the preproduction of the 1954 film Godzilla, its pre-published storyline was very similar to that of The Beast from 20,000 Fathoms and was actually titled The Giant Monster from 20,000 Miles Under the Sea (海底二万哩から来た大怪獣,   Kaiteinimanmairu kara Kita Daikaijū). Like the Rhedosaurus, Godzilla was also initially planned to be a giant octopus. Rhedosaurus creator Ray Harryhausen considered Godzilla to be a "filch" of his own work.
• The Rhedosaurus is featured in posters for the 1953 3D science-fiction film Robot Monster, which was released to American theaters on June 10, three days before The Beast from 20,000 Fathoms was released.
• Harryhausen's protégé Jim Danforth purportedly paid homage to his mentor's work by briefly featuring a creature resembling the Rhedosaurus in the 1970 film When Dinosaurs Ruled the Earth.
• In Gremlins 2: The New Batch, two Gremlins briefly watch The Beast from 20,000 Fathoms on TV, laughing during the scene when the Rhedosaurus eats a police officer.
• The Rhedosaurus appeared in the sixth episode of the second season of the ABC TV improvisational series Whose Line Is It Anyway?.
• Batman #104 (December 1956), in its third story (of three total) and the one on the front cover, "The Creature from 20,000 Fathoms!", features a creature named Bobonga that pays homage to the Rhedosaurus, along with the story's title.
• In the American television comedy series It's Always Sunny in Philadelphia, a postcard featuring a screenshot of the Rhedosaurus from The Beast from 20,000 Fathoms is displayed in the background during the episode "Mac's Mom Burns Her House Down" (season six, episode six) which originally aired on October 21, 2010.
• A dinosaur modeled on the Rhedosaurus appears in issues #2 and 4 of the 2013 5-issue comic book miniseries Dinosaurs Attack! by IDW Publishing. In issue #2, after manifesting in Italy, it battles a dinosaur modeled on the Paleosaurus from The Giant Behemoth (which also manifests in the same area) at the Leaning Tower of Pisa, where it is shoved through the tower by its rival. In issue #4, it appears alongside several creatures as part of a charge against the U.S. military forces, with some of them resembling dinosaurian characters such as Godzilla (who leads the charge), Anguirus, Rodan, the Paleosaurus, Gorgo, Reptilicus, and Gertie the Dinosaur, among others.
  • The Rhedosaurus also appears together with the Paleosaurus in card #10 (of 55) of the Topps trading card series Dinosaurs Attack! (which was the basis for the above-mentioned miniseries), "Italy Under Seige [sic]!". The two dinosaurs are shown fighting each other at the Leaning Tower of Pisa in Italy.
• The scene where a giant Dragonite is attracted to a lighthouse horn scene in the thirteenth episode of Pokémon, entitled "Mystery at the Lighthouse", was inspired by the sea monster in "The Fog Horn".
• Director Daisuke Sato created a version of the sea monster from "The Fog Horn" for an unreleased 2007 short film of the same name. The story would also later inspire his 2019 short Howl from Beyond the Fog.
