I've thought about this and have asked a few paleontologist about that
very subject. What I've come to is this, the reason why there are large
egg clutchs isn't due to the fragility of the hatchlings, but is due to
how many are picked off by predators, and in a smaller part, due to the
the enviroment. If they weren't picked off by predators, they had a
much better chance of living.
Sea turtles are eaten by birds, reptiles, fish...
