When sisters Cassandra Prince and Cynthia Nicholls first pulled a rock-like object from the ground of their outback cattle property, they had no clue it was a 100-million-year-old fossil.
The pair, along with their cousin Sally, are the trio of fossil hunters behind the discovery of Australia's first complete plesiosaur fossil with head and body intact.
"We actually dug that site last year but we didn't go down deep enough. I had a really strong feeling to dig it again this year," Ms Prince said.
