Amid a growing human population, African elephants are confined to an increasingly managed existence. Do we want more for one of the world's most loved species?
An internet-breaking 6'4" steer isn't the only animal to reach gigantic proportions.
The 19th-century British anatomist Richard Owen downplayed the role of colonial contributors and largely ignored the importance of Aboriginal testimony and knowledge in describing the marsupial lion.
How we discovered ancient footprints of early human hunters and their megafauna prey.
Scientists in New Zealand have discovered an extinct penguin known as Kumimanu biceae that was 1.77m tall.
The new Tasmanian tiger genome reveals some fascinating facts about this extinct marsupial, including why they were so similar to dogs, and how they were growing more vulnerable to genetic disease.
'Marsupial lions' aren't really lions - but they did have teeth that formed a pair of secateur-like blades. The newly found species lived in forests of Queensland around 20 million years ago.
Australia was once home to giant fightless birds - much bigger than today's emus and cassawories. But where did they come from, and where did they go?

Large birds once lived across Australia, only to become extinct around the time that giant marsupials and other megafauna died out during the Pleistocene "ice ages".
Layers and layers of sand and sediment collected in Naracoorte Caves create windows into what Australia was like in our recent past.
A burst of wet weather could have helped to kill off mammoths and other large herbivores, by transforming much of the world's grasslands into bogs and forests and depriving megafauna of food.
The extinction of the giant reptiles, marsupials and birds that once called Australia home has been the subject of much debate, including the role early Australians may have had on their fate.
Ships in Australian waters are getting bigger and more numerous all the time. We need a plan to help them avoid crashing into whales and other large sea creatures.

What killed off Australia's giant wombats and other megafauna? New dating once again points the finger at human hunters, rather than abrupt changes to the climate.
Our entire knowledge of one of Australia's extinct ancient giant birds is flawed because experts have been looking at remnants of the wrong egg the whole time.
Every state and territory in Australia should have one: a fossil emblem. Not only can they be good for tourism but they can also help teach people about the ancient history of the regions.
