The original <PERSON> is more gorilla whale than dinosaur. Look at the way he stands somewhat upright with a long tale. Spines down his back not unlike a Dimetrodon which is a distant relative of mammals. The sheer size of <PERSON> is enormous which whales are also way larger than any dinosaur has ever been. Look at the face of <PERSON> he has a wide fully toothed jaw With larger canines in the front. with a blunt nose with nostrils and eyes that point to the front of the face. Dinosaurs have Large teeth that are usaully the same throughout the mouth and nostrils (which can be somewhat close together are usually on each side of the face. The eyes are usually on each side as well.
Dinosaurs were not great swimmers even though there were aquatic reptiles bigger than some dinosaurs on land. Whales however are aquatic but have to breath also. Again <PERSON> is a mutant of many species he could be part fish and amphibian which is well known in evolution that both mammals and reptiles had to come from.
<PERSON>'s legs are very muscular, but he is not a toe walker like most dinosaurs that walked on two legs. Toe walkers look like their knees are backwards but what people think is a knee is actually a heel. 731
The knee is farther up towards the body. Being so large and not a toe walker <PERSON> is much slower than a dinosaur style monster. The 1998 Godzilla (Zilla) is a reptile style monster and was very fast. Did you ever see the original <PERSON> go faster then a casual walk?
The skin on <PERSON> is a mutation but is not scale like in the sense of a dinosaur it is rough and some areas are bone like the fins on the back. Dinosaurs have similar in the bone to scale design, but scales are uniform where <PERSON>'s skin is not.
Now <PERSON> lays an egg to reproduce yes he does do that he is also A-sexual which means only one needs to procreate. <PERSON> laid several eggs because that one was reptile like. <PERSON> lays one huge egg which is more Platypus like. <PERSON> takes care of his offspring and is always protecting it. <PERSON> is similar to crocodile in that aspect it watches the nest makes sure they are ok then will leave the nest after a while.
The movies say <PERSON> is a mutation of a dinosaur a Godzillasaurus that was to please the American public. <PERSON> is also suppose to be invincible due to the G cells that can regenerate any part of him. Of coarse the Americans can beat him with conventional weapons, When the Japanese could not touch him. The 2014 movie fixed the problem with that.
All in all think what you want, but the original <PERSON> is more a Gorilla whale design than any dinosaur design. 167
