It is perhaps difficult for humanity to survive if these giant, bloodthirsty prehistoric creatures were to come back to life.
10 Ancient Animals Resurrected That Could Lead to Human Extinction
Megalodon could reach a maximum length of 18 meters, nearly twice that of an ancient dinosaur.
From about 28 million to 1.6 million years ago, a species of shark known as Megalodon existed. This shark is considered the largest to have ever lived on Earth, with a maximum length of up to 18 meters, three times that of the great white shark. Megalodon’s favorite food included whales and other smaller shark species.
2. Giant Ancient Millipede Euphoberia
Euphoberia had a body structure similar to modern millipedes, except its length could reach 1 meter, making it a formidable predator.
In fact, a small millipede about 25 cm long could prey on birds, snakes, and bats. Imagine the scenario if a giant ancient millipede like Euphoberia still existed; it could spell disaster for human life.
3. Titanoboa
The giant snake Titanoboa.
Not the Anaconda, nor the Boidae or Bolyeriidae, but Titanoboa is confirmed as the largest snake ever recorded on Earth. Living from 60 to 58 million years ago, Titanoboa measured around 42 meters in length and weighed up to 2,500 kg.
It could swallow a Deinosuchus crocodile or even a large bus whole. Research suggests that if the Earth heats up, modern snakes could grow in size similar to their ancestors.
4. Saber-toothed Tiger Smilodon

Smilodon is an extinct genus of saber-toothed cats believed to have lived from 3 million to 10,000 years ago in North and South America.
They possessed the most formidable predatory abilities that instilled fear in all other species.
Smilodon weighed around 350 kg, had a short tail, robust limbs, and a large head. With a size comparable to that of a Siberian tiger, Smilodon was incredibly strong. Their jaws could open to a 95-degree angle, and their canine teeth measured about 17 cm (7 inches) in length.
Deinosuchus Vs. Tyrannosaurus Rex.
Deinosuchus is an extinct genus of crocodiles that lived 80-73 million years ago during the late Cretaceous period.
Much larger than any modern crocodile, Deinosuchus was once considered the most fearsome predator of all dinosaurs.
6. Armored Fish Dunkleosteus
The armored fish Dunkleosteus resembles a robot fish from science fiction movies. This species was real and once existed on Earth.
Its head and chest were covered by armor-like bony plates. They had no teeth but instead had two sharp bony plates that formed a beak-like structure.
Scientists have found specimens of this fish that indicate it could grow up to 10 meters in length and weigh around 4 tons. This aggressive fish would tear apart anything, even feasting on its own kind.
However, due to the absence of teeth, the two bony plates in front were solely for attacking and killing prey, which meant this fish likely suffered from indigestion.
Many fossils often reveal relatively intact remains of unfortunate victims found in their stomachs.
7. Scorpion Pulmonoscorpius

This species of scorpion has a body structure similar to modern scorpions, except for its slightly unusual head with two pincers, and the notable difference is that this scorpion could grow over 1 meter in length.
8. Carnivorous Mammal Andrewsarchus
Carnivorous mammal Andrewsarchus.
Andrewsarchus is a massive carnivorous mammal weighing up to 1,800 kg. With the aggressive temperament of a predator, they would be terrifying creatures if brought back to life.
9. Giant Ape Gigantopithecus
Giant Ape Gigantopithecus.
Gigantopithecus lived between 9 million and 100,000 years ago in Asia, standing over 3 meters tall and weighing 1,200 kg, making it the largest primate known to date. Their teeth adapted to grind and tear various types of food.
10. Ocean Predator Helicoprion
Ocean predator Helicoprion.
Helicoprion was an ocean predator from 310 to 250 million years ago, resembling a shark except for its spiral arrangement of teeth – a heavy-duty weapon for tearing apart its prey. Helicoprion’s body length was approximately 4 meters.
