A GIANT flightless bird, once thought to
be an “overgrown, scaled-up mallee fowl”, has turned out to be something
“unique”, Flinders
University researchers
say.
Flinders University Professor Mike Lee,
based at the SA Museum, helped reconstruct the long-extinct big bird’s family
tree.
“Before, we thought ‘OK, it’s just an
overgrown, scaled-up mallee fowl’,” he said.
“Whereas our research shows that this
bird that went extinct when humans arrived was a lot more unique than people
thought, it was evolving for tens of millions of years on its own evolutionary
trajectory before it was snuffed out with human arrival.”
The research team studied ancient bones
of the Pacific Islands bird (Sylviornis neocaledoniae),
which died out about 2500 years ago.
They found it grew 80cm tall, weighed
30kg and had feet like a chicken.
“We can say it almost certainly didn’t
incubate its eggs in the same way as mallee fowl, by digging a big mound of
earth and all of that,” Professor Lee said.
“Sure enough, it was just a normal
chicken foot, it wasn’t the big spade-like mallee fowl foot that mallee fowl
use to shovel up all the rotting vegetation and earth into a big mound.”
Flinders University PhD student Miyess
Mitri created an artist’s reconstruction of what the bizarre giant fowl would
have looked like in real life.
