Opalised fossils hide in private collections. These palaeontologists rescue them 🦴🌈 | ABC Australia

One in a billion bones becomes a fossil — even fewer turn into precious opal. That's what makes Lightning Ridge, located in the north-west of New South Wales, such a special place. Here, rainbow bones, shells, teeth and plant are unearthed by the regions opal miners. And here lies the challenge. Should the fossil be broken up for its coloured stone and sold as jewellery or should the specimen be preserved for scientific study? Two local palaeontologists Dr Elizabeth Smith and Jenni Brammall have collectively spent over 40 years convincing opal miners, as well as buyers and sellers, of the significance of what they're finding. With the threat of losing fossils to private collections, as well as delicately navigating a multitude of personalities inside the town, we follow Liz and Jenni on their fight to save the opalised fossils and have them placed in a national collection permanently. 00:00 | Rainbow Bones intro 02:48 | Opalised shark teeth fall into the hands of an opal and fossil buyer 04:38 | Meet palaeontologist Dr Elizabeth Smith 05:28 | What did Lightning Ridge look like when dinosaurs walked? 06:11 | How does opal form? 06:59 | How are opalised fossils formed? 08:11 | Everyday life for palaeontologists living in Lightning Ridge 09:47 | When Elizabeth Smith first arrived in Lightning Ridge 12:19 | Lightning Ridge in the 1990s 12:56 | The Australian Museum arrives In Lightning Ridge 13:41 | Meet opal photographer Robert Smith 16:24 | Palaeontologist Jenni Brammall sets out to identify a potential shark tooth 17:51 | How Jenni Brammall became a palaeontologist 18:41 | The fossils of Riversleigh 20:04 | When Jenni first arrived In Lightning Ridge 21:10 | Understanding the miners of Lightning Ridge 22:48 | The story behind Fostoria dhimbangunmal, an opalised dinosaur 23:54 | Growing up as an opal miner in Lightning Ridge 24:57 | Discovering a dinosaur in Lightning Ridge 26:17 | How the myth that the army will seize your fossils began 27:50 | Opal miner Butch McFadden explains the benefits of donating fossils 31:20 | Opalised sharks teeth 32:09 | Inside the Australian Opal Centre 32:54 | The opalised shark tooth lost forever, found again 24:01 | Environmental activism and fossil conservation 35:12 | The fight to save Lightning Ridge fossils from the black market trade 36:34 | Opal mining family decides to hand over fossils to Australian Opal Centre 37:14 | Looking back on the discovery of Fostoria dhimbangunmal 39:00 | Jenni and Liz are called to identify opalised fossils 40:56 | What happens when Lightning Ridge doesn’t have two full-time palaeontologists? 43:10 | The importance of keeping fossils on country Subscribe 🔔 http://ab.co/ABCAus-subscribe ___________________________________________ Web: http://abc.net.au/ Facebook:   / abc   Twitter:   / abcaustralia   Instagram:   / abcaustralia   ___________________________________________ Please note: On most of our videos, the captions/subtitles are auto-generated by YouTube.
