the stegosaur?
In another thread I wrote:
...there were many different species of sauropod dinosaurs with a Brontosaurus-like body shape evolving and becoming extinct over a total period of at least a hundred and fifty million years, while each individual species existed for only a few hundred thousand or a few million years.
The several Apatosaurus species lived in the late Jurassic period about 152 to 151 million years ago, and the several Brontosaur species lived about 155 to 152 million years ago. Dinosaurs became extinct about 65 million years ago.
So there is no way that a sauropod dinosaur living in 1933 could be a brontosaur, an apatosaurus, a diplodicus, a brachiosaurus, an argentinosaurus, a supersaurus, or any other known species of sauropod dinosaur. the dinosaur was a member of a relatively newly-evolved species...
And the same goes for the stegosaur which charged at the crew.
It looked a lot like reconstructions of members of the three known species of the genus Stegosaurus: Stegosaurus ungulatus, Stegosaurus stenops, and Stegosaurus sulcatus, who flourished more or less about 155 to 150 million years ago. The genus Stegosaurus disappeared from the fossil record more than 85 million years before the dinosuars became extinct 65 million years ago, so there is no way the "stegosaur-like" dinosaur at Skull Island could be a member of any known species of steogsaur.
It may be noted that Stegosaur fossils are found in the same region of North America as fossils of Brontosaurus and Apatosaurus and come from the same era. thus it is possible that stegosaurs and sauropod dinosaurs from the same space and time came to Skull Island the same way and became ancestors of the ones found in 1933.
And anyway the King Kong stegosaur was much larger than any known stegosaur, being the size of a very large sauropod dinosaur. The dinosaur seemed to go on forever as they walked past its body stretched out on the ground.
According to Wikipedia, Stegosaurus ungulatus got to be 7 to 9 meters (23 to 30 feet) long and weigh 4.2 to 7.7 short tons, and Stegosaurus stenops got to be 6.5 to 9 meters (21 to 30 feet) long and weigh 2.9 to 5.8 short tons.
Since the King Kong stegosaur looked like could be two or three times the 30 foot maximum length of known stegosaurs, and thus have 8 to 27 times the volume, it should have weighed about 46.4 to 207.9 short tons. Which means that it would have weighed somewhere between a large and impressive sauropod dinosaur and the heaviest weights ever estimated for the blue whale or for Amphicoelias fragillimus https://en.wikipedia.org/wiki/Amphicoelias or Bruhathkayosaurus mathleyihttps://en.wikipedia.org/wiki/Bruhathkayosaurus
I wonder if anyone has estimated how long and heavy the stegosaur in King Kong is. share
