Time is an odd sort of thing – I’m always losing it, but you can never get it back. For example, one year ago, my son wasn’t even born. Ten years ago, I was still at University. A thousand years ago, Vikings were doing their thing in Europe . A million years ago, ancestral humans hadn’t even formed recognisable civilisations. But 600 million years? It almost goes without saying, but that’s a very long time ago. As you can probably guess, quite a bit has changed on our planet in that time.

One of the challenges we’re facing with our new exhibitions in the Science and Life Gallery redevelopment is to make this sort of timescale comprehensible – the amount of time is so big that it is hard to wrap your head around. The first of the four exhibitions to open will be Dinosaur Walk, displaying dinosaur skeletons and others, aims to summarise the last 253 million years of land vertebrate evolution, starting just before the age of the dinosaurs, passing through the Mesozoic where dinosaurs, flying and marine reptiles ruled their domains, through to their extinction and the eventual rise (and demise) of the megafauna.

So how do you fit something as mind-bogglingly vast as hundreds of millions of years into an exhibition space less than 50 metres long at Melbourne Museum ? The answers to that are, with careful selection of display objects, some very clever (and patient) exhibition designers and an equally talented exhibition team!
