The Head of the Quetzalcoatlus

The Quetzalcoatlus was a dinosaur the size of a giraffe. Its neck was equally long as that of a giraffe, and it walked about on four legs.

Yet it could fly! When spreading out its front legs and fifth finger, it unfolded wings with a total wing-span of 16 meters.

The fact that an animal like that could fly is in itself baffling. However, that is not its only mystery. There is another strange thing about this animal that makes no sense. Its head, including its beak was half the length of its giraffe-like neck. Instead of a tiny head perched on top of its long neck, like that of a giraffe, it had an enormous head with a giant beak.

How on earth could it carry such a head on top of its neck, let alone fly with it?

Making this all the more mysterious is the fact that these flying monsters were predators. They could catch prey with the tip of their beaks. That would produce a tremendous torque on their neck. How could it be that these animals did not break their necks? It seems that an abrupt movement of their heads would in itself be sufficient to snap their necks. Yet, they could hunt and catch prey with ease. They must have been able to move their heads about swiftly and forcefully.

The only way this could be possible is if the inertia associated with their heads was less. With less inertia, there would be less torque. Only a world where everything was substantially less massive would allow an animal like the Quetzalcoatlus to hunt.

The Quetzalcoatlus could only have existed if both gravity and inertia were less by a substantial amount. This animal represents proof that it is not only gravity that has increased with time. Inertia has increased too. Not only has Earth grown more massive, so has all the animals and everything else on it. Whatever is happening inside our planet is happening in everything else too.

This is exactly what we should expect based on Halton Arp's variable mass hypothesis. Inertial mass increases over time.
