Why We Made The List

Initially, our team built a list of 100 species that were considered to be the best candidates.

This was based on what they found to be some of the meanest, funniest, or most creative names.

As we mentioned earlier, this is based on either their given name or the name’s meaning.

We looked for names that stood out from the crowd, were unique to the species, and showed a bit of personality.

We then further narrowed our list down to 20 species that best represented what we thought were the greatest names of all.

We hope you enjoy it. Surely, you will encounter some species you’ve never heard of before.

LocationNew Mexico

Let’s start with the Earth Shaking Lizard, Seismosaurus.

Seismosaurus was a colossal giant that inhabited Western North America.

Considered one of the longest species that roamed around the planet, Seismosaurus existed to be 150 feet (46 meters) long.

Its Earth-shaking name comes from its heavy weight, which can be approximately around 100 tons.

Weight7 tons (15400 lbs)
LocationArgentina (South America)

Tyrannotitan was one of the ferocious predators that roamed in the ancient landscape of Argentina.

Although it is not related to the Tyrannosaurus, it was still an apex predator ruling for millions of years, hence its Tyrant Giant name.

Tryannotitan was bipedal and had a robust and muscular build, with a long muscular tail for balance and agility.

As a hungry carnivore, it has eaten lots of dinosaur species and was heavily built to take down any prey.

With its massive size, speed, and running prowess, it can quickly catch any prey with pursuit and ambush.

Don’t get alarmed with this alarming lizard because you will have a knack for it once you do.

Tarbosaurus was a close cousin of the famous Tyrannosaurus that ruled the landscape of East Asia.

Closely similar to that of the Tyrannosaurus, Tarbosaurus was a massive creature and one of the largest tyrannosaurids ever found.

This ferocious dinosaur measured about 10.57 meters (34.7 feet in length and stood at about 3.2 meters (20 feet tall).

Tarbosaurus used its turbo speed to alarm prey when hunting or pursuing prey, hence its name as the alarming lizard.

It is clear, to some degree, that Tarbosaurus is one dinosaur that you won’t even like to meet because of its moody behavior.

Let’s welcome the fire thief dinosaur to the list.

Pyroraptor’s origin started when it was first discovered after a forest fire, hence its fire designation.

Quite small in size, its bird-like appearance isn’t just for a show.

When hunting, Pyroraptor uses their enlarged curved claws to kill their prey, day in and day out.

Apparently, Pyroraptor relied on a “puncture and pull” technique to feed themselves and preferred to hunt larger prey.

Undoubtedly, Pyroraptor is an amazing dinosaur with fast hunting speeds and a strategist like no other.

Their skull was more elongated and had many knobs and spikes.

Measured to be around 13 to 15 feet long, it was a relatively small dinosaur compared to some of its contemporaries.

Noticeably, Dracorex’s forelimbs were quite shorter and relied on its hindlimbs for movement, enabling Dracorex to move quickly and efficiently with its two legs.

Studying its teeth, it was revealed that it was herbivorous and depended on plant life for survival.

Upon its discovery, Cryolophosaurus was first the first officially named non-avian dinosaur.

Known as the frozen-crested lizard, Cryolophosaurus had been an apex predator during its time.

Cryolophosaurus was 2.3 meters (7.5 feet) tall and had a robust build, with short forelimbs and strong hind limbs.

As an apex predator, this frozen-crested lizard is thought to have fed on local prosauropods.

Deinotherium was one of the largest prehistoric elephants roamed around Africa and a part of Eurasia.

Having longer legs, a short trunk, and tusks in their lower jaws, the appearance of Deinotherium’s is somewhat different from modern elephants today.

Deinotherium was a massive creature with a body mass of 13200 kg (29100 lbs) and a height of 4.01 m (13.2 feet).

Compared to other elephants, the Deinotherium skull is also different, comprising a flat forehead and a large nasal opening.

This terrifying dinosaur got its nickname because of its heavily ornamental skull, covered with spikes and knobs, resembling that of the devil.

Considered to be a small dinosaur, Stygimoloch had a compact and robust body structure, suggesting that it was capable of hunting prey quickly and easily.

One peculiar behavior of male Stygimoloch is that they head-butt each other to get the right to mate with the females.
