Dinosaur eggs by the dozen! Image: The Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences
Almost two years ago, we reported on the discovery of a special fossilized dinosaur specimen – the first pterosaur egg preserved in 3D! Pretty impressive, huh? Since then, there have been some other interesting finds. So we thought it was time to crack open the fossil files and take a look at some of the most egg-citing dinosaur egg finds!
Dr Thomas Rich is Senior Curator in Vertebrate Palaeontology at the Melbourne Museum. He says: “Unfortunately, there hasn’t been a single egg found in Australia. But fossilized dinosaur egg discoveries aren’t all that rare, if you know where to look. Argentina, Montana and China are some of the most significant discovery sites.” Continue Reading →

The Aussie bush was once full of cute, furry creatures. But these days, quolls, bandicoots and bettongs have a hard time keeping safe from feral foxes and wild dogs. So how can we protect our native animal friends?
Out at Mulligan’s Flat Woodland Sanctuary on the outskirts of Canberra, the rangers built fences to protect the native wildlife. The fences are great at keeping ferals out – bettongs and bandicoots are safe in the reserve. But the rangers discovered a flaw in their fence when they recently added quolls to the population. Fences will keep the nasties out, but they don’t keep the natives in. Continue Reading →

On 2 March this year, two long-term International Space Station residents returned to Earth. Scott Kelly and Mikhail Kornienko both spent 342 days in space. Their year-long mission included space walks and Earth photography. But the most important experiment was on themselves. How does a person react to a year in space?
Throughout their expedition, scientists conducted many experiments on the duo, checking reaction times and making sure they were still healthy. But while Scott and Mikhail were floating in space, there was also a third participant. Continue Reading →
