The fossilised remains of a 780,000 year old prehistoric bird have been found in a cave on the Nullabor Plain.

The bird, possibly a wedge-tailed eagle, was unearthed in a cave known as Leaena’s Breath Cave.

“This cave has been acting as a bird death trap for at least a million years, which is just one thing that makes this one of the most interesting and unique palaeontological sites in Australia,“ palaeontologist Dr Gavin Prideaux said.
