Odontotyrannus brontovox Picture

Am just copying the description from my website:

These creatures are of an older, primitive, cold-blooded strain of hexapod carnivores. Being cold-blooded and not very agile or fast, most of their kind has died out, outcompeted by the warm-blooded, faster predators. The only thing they are good at, is being huge and strong, which is why the only surviving species are enormous, the largest land-predators on the planet. They cannot run or jump, but they can stand on four legs for short moments, when they use their front limbs as weapons. Mostly however, they stay on all six, and use their formidable jaws as weapons, both in offense and defense.

Being cold-blooded has many disadvantages, but it has one advantage - their size is the only thing saving this line of creatures, and if they were warm-blooded, they could never have reached this size, as they would have required a tremendous amount of food. Also, their method of hunting takes a lot of time, time that a warm-blooded creature wouldn't have before starving.

End of copying.

Their method of hunting is like that of Giganotosaurus hunting Argentinosaurus - enormous predators with thin jaws containing knife-like teeth, slicing off pieces of flesh and either having a mouthful with the prey surviving, or having the large prey animal slowly bleeding to death. (Now, I'm not saying Giganotosaurs were cold-blooded, theropods almost certainly were all warm-blooded.)

This thing is supposed to get up to 6-7 meters in height, but I may be exaggerating that, so let's say around 6 meters. This individual is probably a smaller specimen or even a subadult, as it is about 5 meters at the shoulders, and 14 meters long.

Shocked 2 meter humanoid standing underneath. The beast itself is in a defensive position (front foot lifted, jaws open, stance of first two leg pairs, whipping tail), perhaps against a bigger Odontotyrannus.

If you wonder where I got the name, I have a theme in some creatures, in naming them after mythological animals.
Not that these themselves are representatives of those mythological creatures, but if you came to another planet, and even some animals here on Earth, if they resemble animals from mythology, you may name them after them. Such as the genus Draco here on Earth, or if you found a vaguely horse-looking tetrapod with a single horn, you might want to call it a unicorn.

So this one is named after the greek mythological creature Odontotyrannos - according to Wikipedia it was; "a Greek mythological beast that attacked Alexander the Great and his men at their camp. It was reptilian, one-horned, and green-tinged. It was eventually slain by the Greeks and it took 1,300 men to carry its body away."

And now to the fun part...

"...Many scientists have proposed the possibility that it was a rhinoceros."

Well, I guess anything's possible.
