I wonder if anyone thought of examining the embryos, to see if there
were any ready to hatch that you could tell if they had a warm blooded
heart?

What is the tallest known cold blooded animal?

Snakes lizards all stay close to the ground. The rest are in the water
or swamps for boyancy,as far as I know, and they just cease to function
in cold weather, and dinosaurs like the Tyrantosaurus, have been found
in frigid northern climes.

And just by looking at these things, you cannot imagine them not being
a grazing herbivore, or else how could they feed that huge body? They
would have to almost hibernate. Anyone who has ever had a lizard for a
pet, knows they spend most of their time not moving at all.

These thing did lift their heads because the evidence is what they ate,
grew in trees.

And the dinosaur heart we do have, Willo, is a warm blooded dinosaur.

So all we have for evidence that they were cold blooded is that they
laid eggs like a reptile, but so does a chicken.

They are far more like a giraffe, than a crocodile.

Where are all the tall cold blooded animals?
If this animal did not have a high metabolic rate, what would happen to
the fluid in its head?

Cold blooded or not, unless it was under pressure, it would drain to
the lower extremities by the force of gravity.

So to just say, well either it didn't lift its head, or it was cold
blooded, thinking that by saying it is cold blooded, no one will
investigate further, is pure nonsense.

And that leads to the inevitable, that paleontologists are just
stalling while physicists come up with an explanation as to how gravity
became 20% greater today than it was then.

Maybe the expansion of the universe has something to do with it.

If you consider that we are accellerating into hyperspace, that is what
the force of gravity is, the expansion of the universe, and you can see
this by the fact that galaxies are moving away from us at the speed of
light, that is a high rate of accelleration.

So it is a bit unnerving to consider the possibility that the entire
universe is getting heavier. That all planets within it, would be
feeling a greater gravitational force today than 200 million years ago.

And if it is a local phenomena, then that 20% still must be accounted
for some how by some change in the solar system in our neck of the
woods.

It is possible that super volcanoes, were responsible for the ice ages,
and the Great Dying may have been was caused by that, the release of
CO2 and freezing temperatures and soot, poisionous atmosphere etc.

But the demise of the large dinosaurs and this 20kg limit of survival
during the KT event, and leading up to it, in all probability, was a
gravity related problem.

These beasts could not circulate their fluids under today's
gravitation.
