Doubt has been cast over the only known piece of evidence that large
carnivorous dinosaurs once roamed Australia, following new research by
The University of Queensland (UQ). A set of footprints at Lark Quarry
Conservation Park, south of Winton in central-western Queensland, was
the only evidence that Australia was once home to large carnivorous
theropod dinosaurs as big as Tyrannosaurus rex or Allosaurus fragilus.
For the past 30 years, these footprints were believed to show a large
meat-eating dinosaur chasing a herd of smaller dinosaurs. The site is
world famous as it is also thought to be the only example of a dinosaur
stampede.
However, a new study by palaeontologists from UQ has shown that these
tracks probably don't belong to a large theropod at all, and were most
likely left by a large herbivore akin to Muttaburrasaurus. UQ's School
of Biological Sciences PhD candidate, Anthony Romilio, led the research,
which has been published in the latest issue of the journal Cretaceous
Research.
