Hollis, C.J. 2003 Fatal impact : the asteroid that wiped out the dinosaurs. Wellington: Royal Society of New Zealand. Alpha 116. 7 p.
Abstract: Sixty-five million years ago an asteroid the size of Wellington Harbour crashed into the shallow seas off the Yucatan Peninsula, Mexico, and caused the greatest catastrophe of the last 250 million years. The impact caused the extinction of the dinosaurs – the dominant animals of the previous 150 million years – along with about half of all species of plants and animals then alive. Evolution of new species and the recovery of ecosystems on land and in the sea took thousands, possibly millions of years. (auth)
