Ancient Earth was filled with animals but after the extinction of Dinosaurs,  many species of animals went extinct.  Two-thrid of the extinct animals got destroyed by humans.  In the concept of self-defense, human has become the dangerous Predator and killer of all time. People are trying to bring back most of the extinct animals due to various reasons, especially to protect the ecosystem. But is it worth bringing back the terrifying extinct animals?  Because terrifying species are much bigger than modern animals, where even a snake will be in a size capable of eating a crocodile and not once you like to live in the same period. so you’ll be glad that they are extinct. 

So here are some ancient creatures and terrifying animals you are glad are extinct.

Extinct animals

Megalania

Extinct animals

About 2.5 million years ago,  survived the largest terrestrial lizard was called the Megalania in Northern and Western Australia and it went extinct 50,000 years ago.  It was long as a two-story building and the weight of a heart of a Blue Whale.  It is considered the most venomous lizard.  In the food chain, humans were their Rivals and you cannot find them easily as they hunt in ambush. 

So whenever a human sees Megalania,  they try killing it because,  if they catch you they can instantly disable it by cutting the tendons with is razor-sharp teeth.  Immediately it will rip open your belly and start eating you alive.  There were some speculations in Australia during the 1990s,  that they have seen a Megalania alive, but it is proven that this species got extinct. 

Short-faced bear

The fastest running bear ever lived was the short-faced bear also called as bulldog bear which was six feet at Shoulders.  They lived-in Nothern America from 1.6 million to 10,000 years ago. Among the extinct bears,  this was the largest land-living carnivore almost twice as big as the brown bear living today.

It was likely a powerful hunter which could kill large prey. They have no trouble finding you, because of its distinctive super sensitive nose.  The lateral teeth of the bear will effectively cut not only your tendon but also your bones, and it would have frightened the early Egyptians.

Helicoprian

Helicoprion was a predatory fish similar to the sharks present today, and this is one of the Terrifying animals you are glad are extinct. They ended up about 225 million years ago.  They are considered as one of the most dangerous fish being 7 meters long and 380 kg in weight.  The main characteristics of the Helicoprian fish were their teeth which had an unusual ability.

The teeth were placed in a deadly spiral pattern and it didn’t shed them, instead, new teeth were grown, pushing the older teeth forward. this gives us an idea, of how it could have killed its prey, and so we are glad that we didn’t share the time with them. 

Giant sea scorpions

Unlike the modern Scorpions, there lived the giant sea Scorpions,  the ancient predators, who lived 467 million years ago, which was the size of a person and some were even bigger. they are also called eurypterids and are recognized as the biggest arthropods on earth.

They were boneless predators and were known to be the original sea monsters, with pinching claws and used their tails as weapons to kill their prey. They were even able to kill with the horizontal slashing motion of their tails. Originally they lived in the sea, but by the time they started living in freshwater. If humans had shared the time and earth with these extinct animals,  it would be a deadly and terrifying moment.

Haast’s eagles are extinct animals known for their capability of preying on children and are considered as the biggest, worst and magnificent eagle ever lived. They terrorized the south Island of New Zealand weighing 10 to 15 times their own bodyweight having a wingspan at about 9 feet and it is believed that they would swoop down at speeds of nearly 50 mph to attack using its talons to kill them on the ground. It took the place of the apex predator who hunted grazers and when the Maori hunted the moa to extinction, there was no prey large enough to sustain the Haast’s Eagle so they got extinct quickly. 

Titanoboa Cerrejón

This is known to be one of the world’s richest and most important fossil deposits. They are said to exist 58 to 60 million years ago which is the Paleocene epoch. It is one such beast that can even prey on a crocodile easily. The length is said to be 13m and weighed more than 1,100 kg with a thick body that was capable of reaching up to a man’s waist. They were found in Colombia and said to live on the surfaces of lakes or rivers similar to anaconda. It drags the prey underwater and before finishing it off, it winds and twists the struggling prey.

The period was a reign of terror. This snake is the only species that can be described as the biggest, largest, and heaviest snake discovered ever. The giant size says that Titanoboa is similar to the snakes shown in the terrifying Hollywood movies. And they remained the largest predator after the extinction of dinosaurs and they are believed to be the ancestors of the Boa constrictor and anacondas. They were not venomous but large constrictors. Moreover, they were capable of striking at an incredible speed, that crushed the prey with a constricting force of 400lbs per square inch. So this is one of the terrifying animals you are glad are extinct.
