Mette Elstrup Rasmussen, Notes on the morphology and the orientation of the forelimb of Ouranosaurus nigeriensis. Oryctos 1, 127-130.
The forelimb of O. nigeriensis was closely examined. In the wrist, the intermedium is fused to the radiale and not, as previously thought, to the ulnare. The morphology of the forelimb, and particularly that of the radius and ulna, has implications regarding the orientation of the manus. In the articulated forelimb, the palm of the manus would have faced nearly medially, not posteriorly, as it has often been portrayed. The medial orientation is even more pronounced in the forelimb of other iguanodontids.
