1. Hynodosaurus and Neptune
The Cretaceous period was essentially a barbaric age on Earth, a period of active monsters, including: Henochosaurus and Neptunosaurus, whose adults would allow their cubs to hunt mackerel. They do not use sharp teeth or two rows of attached teeth in their mouths to deal with their prey, but swallow the prey in its entirety.
2. Ridge Dragon
Ridgedosaurs were a very large, fast-moving predatory dinosaur that could reach 60 feet in length and grow up to 5 feet with a crocodile-like jaw that could swing its powerful tail very flexibly. Ridged Dragons are probably the largest predators on land to date.

Researchers have found that chameleons do not change color through pigments, but by adjusting the nanocrystals on the surface of the skin, and change color by changing the refraction of light.
Michel Milinkovich, a biologist at the University of Geneva, said: "We were amazed. It was once thought that they change color through pigments, but the real principle is completely different. ”
Male chameleons can make their appearance more gorgeous, in order to attract the opposite sex, scare off love enemies, or make their appearance more inconspicuous, so as to avoid predators.
3. Giant tooth Dunn's fish
The Dunn's fish was a terrible prehistoric fish, its teeth were like sharp daggers, and its body was about 30 feet long. Scientists have analyzed that Dunn's fish has a strong bite force and can bite any object. Currently, the most powerful species of living creatures on Earth is the coyotes, about 2,000 Newtons. They easily crush bones, compared to tyrannosaurs with a bite force of about 13,000 Newtons. Dunn's fish can bite at 150 million pascals and about 22,000 pounds per square inch.
4. Extreme Edition Tyrannosaurus Rex
It would be very bad to encounter a Tyrannosaurus rex face-to-face encounter, with the two most powerful species of the Tyrannosaurus rex family being Gigonotosaurus and Carcharodontosaurus.
Both species lived about 100 million years ago and were about 45 feet long, and Sharktooth is considered the second largest predator on land in history, with Gigonotosaurus living mainly in present-day South America.
5. Super Sea Monster
Cyruosaurus and "Slippery Toothosaurus" are the most feared prehistoric species in the ocean, with similarities to modern crocodiles, reaching up to 33 feet in length, and the jawbone of a corpse bone sample found so far can reach 10 feet long. Some scientists have speculated that the slippery toothed dragon could actually reach 50 feet in length and, like Neptune, was able to swallow other sea monsters in the ocean.
With "banana-like" teeth, Chlordosaurus even swallowed its own cubs, and its thick jawbones could crush ammonite shells, a species of squid with a shell.
6. Horror pigs
The horror pig, whose body resembles a rhinoceros and has the characteristics of a modern African buffalo and a jaguar, suggests from its name that it is an animal with sharp, extremely destructive teeth, and it was for a time called "dinosaur".
They are a kind of "opportunistic omnivorous," meaning they will feed on any prey.
7. Overlord Dog
It looks like the zombie dog in the sci-fi movie Resident Evil, with a body shape close to a bear, sharp canine teeth, and a skull 3 feet long. The Tyrannosaurus is the largest species of wolf lizards, with canine teeth up to 4 inches long. The Tyrannosaurus dog is considered a strong predatory species on land during the Permian period, and disappeared from extinction during the Permian-Triassic period.
A giant carnivorous bird with a wingspan of 8.40 feet
A prehistoric dinosaur was a giant pterosaur that soared through the air at the end of the Cretaceous period, and its family members included: Aeolian Pterodactyl, Pterodactylosaurus, and Pterodactyl A. With a wingspan of up to 40 feet, they are veritable aerial giants that can launch deadly attacks on prey. At the same time, this 12-foot-tall carnivorous giant bird is about the same height as modern giraffes and can also run like horses on land.
