JINTASAURUS MENISCUS YOU & LI, 2009

Jintasaurus comprises an incomplete posterior skull roof and braincase. It was found in the Yujingzu Basin, Jinta County, Ganzu Province, China, and derives from the Xinminpu Group (Aptian−Albian).

Cranium

The skull roof is broad and flat, and the frontal contributes to the dorsal margin of the orbit. The skull profile (in occipital view) is low and broad and resembles that seen in Ouranosaurus ( Taquet, 1976) ; the paroccipitals are elongate, curved, and taper to a blunt point.

Taxonomic note

It is impossible to draw comparisons between the cranial elements of Jintasaurus (well described and illustrat- ed) and the remains of its sympatric contemporary Xuwulong (below). Doubts must be expressed over the validity of Jintasaurus and Xuwulong as separate taxa.
