Crazy Ted Holden has an interesting take on the impossibility of the larger dinosaurs having the muscle strength to stand in Earth’s current gravity. Elephants are as big as it gets on the planet these days. Ted presents data on muscle strength as a function of cross section of muscle mass vs compression loading on legs and hips and tension loading on necks and tails. The largest dinos stood around 40’ tall. Computing for pressure gives a pressure of about 18 lbs in sq, whereas human blood pressure is about 2 lbs per in sq. A human blood pressure of 3 lbs per in sq would blow out into an anurism and cause blood to leak into the lymph system and cause fatal swelling throughout the body. So unless dinosaur had galvanized pipe for blood vessels, there is a serious hydrostatic issue there.
Additionally, the cantilever forces on neck and tail sinews with the dino’s neck extended horizontally would tear any sort of collagen molecule cabling that known biology would be capable of.
There is also the problem of pressure head in pumping blood to the dinosaur’s head. Giraffes are barely able to pump blood to their brains and easily suffer cardiovascular collapse when highly stressed. Pumping blood any higher than a giraffe’s head would lead to congestive heart failure and bleeding out through capillary permeability.
Frankly, I think crazy Ted hammered it on this one, but I am aware that he goes off the deep end on other of his fave issues. And, yah, neanderthal eye sockets aren’t really that much bigger than cromagnon eye sockets, and eyeball size certainly is no indicator of enhanced night vision.
Here’s a suggestion - instead of waving people off a particular theory as crackpot, why not point to the crackpot’s evidence and let people decide for themselves. Here’s Ted’s analysis of dinosaur scaling -
