Weewarrasaurus is a genus of ornithopod dinosaur from the Late Cretaceous of the Griman Creek Formation near Lightning Ridge, in New South Wales, Australia. The type and only species is W. pobeni, known from the holotype, an isolated dentary preserved in opal, as well as a secondary referred dentary. It is thought to have co-existed with multiple other ornithopods of different sizes and lineages.

Right dentary in (A), medial; (B), dorsal; and (C) lateral views. Dashed black lines represent approximate contours of the missing areas. Dashed red lines indicate the distinctive banding pattern in the opal used to estimate the extent of the missing area. (D–F) Three-dimensional renders of the posterior dentary fragment in (D) lingual view showing erupted (blue) and developing germ teeth (pink); (E) Same as (D) but with dentary removed; (F) dorsal (occlusal) view of tooth row. (G-J) Three-dimensional render of the best-preserved tooth in (G) mesial, (H) lingual, (I) distal, and (J) labial views. (K) MicroCT scan of the posterior dentary fragment in axial view showing preservation of cancellous bone. Abbreviations: cab, cancellous bone; cr, tooth crown. Photo credit: Phil Bell. © Phil R.
