A Drought in the Red Centre - 7 million years ago
Alcoota Station near Alice Springs has a huge number of fossils in one site. Very few fossils are complete.
What seems to have happened is a drought hit 7 million years ago. The dinosaurs ran out of herbage to graze on. Not wanting to leave their shrinking waterhole they died en masse when the water ran out. Their bodies fell into the wet clay and decomposed leaving behind bones that broke as the clay dried.
Some time later, massive floods washed these bones down into a flood plain where they have been excavated for the last twenty five years. Several new species have been discovered.
