When the Japanese freighter Eiko-maru is destroyed near Odo Island, the Bingo-maru is sent to investigate, only to meet the same fate with few survivors. A fishing boat from Odo is also destroyed, with one survivor. Fishing catches mysteriously drop to zero, blamed by an elder on the ancient sea creature known as "Godzilla". Reporters arrive on Odo Island to further investigate. A villager tells one of the reporters that "something large is going crazy down there" ruining the fishing. That evening, a ritual dance to appease Godzilla is held during which the reporter learns that the locals used to sacrifice young girls. That night, a large storm strikes the island, destroying the reporters' helicopter, and an unseen force destroys 17 homes, kills nine persons and 20 of the villagers' livestock.
A saber-toothed squirrel (known as Scrat) is trying to find a place to store his prized acorn. Eventually, as he tries to stomp it into the ground, he causes a large crack in the ground that extends for miles and miles and sets off a large avalanche. He barely escapes, but finds himself stepped on by a herd of prehistoric animals. The animals are trying to avoid the ice age by migrating south. Sid, a clumsy ground sloth left behind by his family, decides to move on by himself but is attacked by two Brontops whom he angered. Sid is soon saved by Manfred ("Manny"), an agitated mammoth who fights them off and is heading north. Not wanting to be alone and unprotected, Sid follows Manny. Meanwhile, Soto, the leader of a Smilodon pride, wants revenge on a group of humans by eating the chief's baby son, Roshan, alive. Soto leads a raid on the human camp, during which Roshan's mother is separated from the rest and jumps down a waterfall when cornered by Soto's lieutenant, Diego. For his failure, Diego is sent to find and retrieve the baby.
Near the end of the Cretaceous, a series of catastrophic events are causing intense drought, and several herds of dinosaurs seek one of the last livable places, a paradise known as the "Great Valley." Among these, a diminished "Longneck" herd gives birth to a single baby, named Littlefoot (Gabriel Damon). Years later, Littlefoot plays with Cera (Candace Hutson), a "Three-horn," who was trying to smash a beetle until her father (Burke Bynes) intervenes; whereupon Littlefoot's mother (Helen Shaver) names the different kinds of dinosaurs: "Three-horns," "Spiketails," "Swimmers," and "Flyers," and states that each has historically remained apart. That night, as Littlefoot follows a "hopper," he encounters Cera again, and they play together briefly until a "Sharptooth" appears. He attacks them, before Littlefoot's mother comes to their rescue. During the fight, she suffers severe back and neck injuries from the Sharptooth's teeth and claws. At that same time, an "earthshake" opens a deep ravine that swallows up the Sharptooth and divides Littlefoot and Cera from their herds. Littlefoot finds his dying mother, and receives her final words of advice in favor of his intuition.

The film depicts the event of 1990, when American paleontologist Sue Hendrickson working with Pete Larson and his team discovered the largest and most complete Tyrannosaurus rex ever found (nicknamed "Sue") while digging in the badlands of South Dakota. The skeleton was seized from Larson by the federal government, followed by a ten-year-long battle with the FBI, the National Park Service, the Bureau of Indian Affairs, and Maurice Williams, the landowner on whose property the bones were discovered. Pete Larson also spent 18 months in prison.
Suneo shows everyone but Nobita a fossil of dinosaur claw. Angry, Nobita claims he will be able to find a living dinosaur. As Doraemon refuses to help him, he digs on a hillside, but instead earns punishment from a landlord nearby who forces him to unearth a hole in the ground. He finds an egg-shaped stone underneath and quickly uses a time wrap to return it to its former form and after warming it, the egg hatches to reveal a Futabasaurus, who is subsequently named Piisuke by Nobita. Instead of immediately showing it to the others, Nobita waits it grow while making a deal with others. As Piisuke grows too large and is in danger of being found, Doraemon and Nobita transport him to 100 million years ago in the Late Cretaceous period. They are attacked by a mysterious assailant who previously tried to make a deal with Nobita to sell Piisuke, though they manage to escape. Left with no proof, Nobita instead shows them Piisuke through a television monitor, but realizes that he and Doraemon had unknowingly transported Piisuke to the North American shore after the time machine was attacked by the assailant. They and the others decide to go there, but the time machine is overloaded and crashes off.
Suneo shows everyone a fossilized claw of a Tyrannosaurus rex and Nobita is angry that he doesn't get a look. Nobita claims that he will be able to find a living dinosaur. Panicking, Nobita researches on dinosaurs and starts digging in a hill. But then, a landlord shouts at him and makes him dig a hole in the ground to dispose of some egg shells. Nobita unearths a rock shaped like an egg. Using the time-wrap, he returns the rock into its former form and plans to hatch the egg. He spends a day and night wrapped tightly in a blanket with it on his futon, despite it being the peak of summer. A "Futabasaurus" comes out, and Nobita decides to name the plesiosaur Piisuke. Suneo and Gian come looking for Nobita but because Piisuke is still too small, Nobita doesn't show them the plesiosaur and instead makes a deal with them. If he cannot show them a real dinosaur, he would have to eat spaghetti through his nose. Meanwhile, Nobita and Piisuke form a strong bond between them with Nobita working very hard to make sure the baby plesiosaur is well looked after, feeding it his own dinner of sashimi and playing with it. He grows very attached to Piisuke.
The story involves four teenage comrades who take a rowboat along a "river of time" that flows into a mysterious cave and emerges on the other side onto a strange, primeval landscape. The boy actors were Josef Lukáš (Petr, the main narrator), Petr Herrmann (Toník, who also narrates in part), Zdeněk Husták (Jenda), and Vladimír Bejval (Jirka). As they make their way upstream, they realise that they are travelling progressively farther back in time, and facing various perils as they do so (but learning much about prehistoric life in the process). The animals depicted in Cesta do pravěku were never shown interacting with animals of other periods and it is assumed that different parts of the river represented distinct time periods. The plot is somewhat similar to that of the novel Plutonia (1915) by the Russian palaeontologist Vladimir Obruchev, in which a team of Russian explorers enter the Earth's crust via an Arctic portal (a huge depression in the Earth surface created many millions of years previously by the impact of a giant asteroid, into which prehistoric animals had entered), and follow a river that leads them through a sequence of past geological eras and associated animal life. Some scenes in Cesta do pravěku recall Arthur Conan Doyle's 1912 novel The Lost World, with four male protagonists exploring a prehistoric world where they find evidence of native human habitation, are attacked by a group of enraged pterodactyls, witness a twilight fight between a carnivorous dinosaur and a herbivorous one, encounter a Stegosaurus up-close, and see one of their members (Petr) pursued by a Phorusrhacos.
