The first evidence of ankylosaurian thyreophorans from the Winton
Formation (late Albian–Cenomanian) of central-western Queensland,
Australia, reveals new information about the temporal and
palaeobiogeographical range of these dinosaurs within Gondwana. The
material, which comprises isolated teeth, is the youngest evidence of
ankylosaurs in Australia. Although the Winton teeth exhibit a suite of
pleisiomorphic characteristics that are also seen in other Australian
and Gondwanan ankylosaur taxa, they are morphologically distinct and
very likely represent a new taxon. Their discovery adds to the growing
body of evidence indicating that thyreophorans, and in particular
ankylosaurians, constitute a diverse and important component of
Australia’s mid-Cretaceous dinosaur fauna.
