Therizinosaurus is joined by 22 other dinosaurs in this digitally augmented exhibition. Mikael Siversson is Curator of Palaeontology at the Western Australia Museum in Perth. The exhibition also has plenty of Mongolian dinosaurs.

“Mongolia has dessert outcrops and exposed cliffs, with not a lot of soil coverage,” Mikael says. “This means dinosaur fossils from Mongolia are particularly well preserved, thanks to the environment.”

It’s not just old bones that have been unearthed (in Mongolia and other parts of the world). Fossilised dinosaur dung also helps palaeontologists with their research.

You don’t have to be a scientist to work out that an 8kg piece of dung came from a pretty big creature. Scientists have, however, analysed stuff like this to work out dinosaur diet.

“It was found to be full of bone chips,” Mikael says. “It was linked to T. rex, as he was thought to be a bone cruncher.

“Bite marks have also been found on bones. From this we know that T. rex sometimes ripped the head off the Triceratops to get to the neck muscles.”
