History has been unearthed at an opal mine near Lightning Ridge.
A jaw bone fragment of a dinosaur believed to be more than 100-million years old has been found preserved in opal.
UNE Palaeontologist, Dr Phil Bell led the team who made the discovery of the Weewarrasaurus pobeni.
The ancient herbivorous reptile was said to walk on two legs, and was about the size of a kelpie dog.
It’s the first new dinosaur to be named in New South Wales in nearly a century.
