00:01All around Brisbane's CBD you pass by heritage listed buildings like St Stephen's Cathedral.
00:08While these buildings are a part of our colonial history, their walls may contain clues of our prehistoric past.
00:16I do glance twice to see what evidence might be hidden.
00:21There's a strong chance the sandstone used in Brisbane's oldest buildings,
00:25including the General Post Office, St John's and St Stephen's Cathedrals, contain fossilised dinosaur footprints.
00:34We can safely say that they contain sandstone blocks from that ancient world of 230 million years ago.
00:44A time when the sauropodomorph walked the earth on its two hind legs.
00:48The smaller ancestor of the long-necked Brachiosaurus, it reached human hip height.
00:53It's also responsible for these tread marks unearthed in Brisbane.
00:58The thing that really tickles me is that there were stonemasons looking at big blocks of sandstone,
01:04going, oh heavens there's a floor in it, there's a footprint.
01:08The sandstone was mined in the mid-1800s at Petrie Quarry, now the inner north suburb of Albion.
01:15It may seem unusual that in a capital city that we find evidence of dinosaurs,
01:22but really all you need is the right age material and a keen eye and some conviction to investigate.
01:31Proving not all dinosaur discoveries are made in the outback.
