How can be seen the evolution of Diatryma and Dromornithids from
Presbyornis-like birds? From fish-eaters becoming increasingly more

If phorusrachoids were common in South America and Antarctica perhaps they
existed in Australia and were overhelmed by thunder birds (thunder gooses?).
And about that Cretaceous French giant bird Gargantuavis? What was it?
