Mahuidacursor lipanglef
Taxonomy
Mahuidacursor lipanglef was named by Cruzado-Caballero et al. (2019). Its type specimen is MAU-Pv-CO-596, a set of postcrania, and it is a 3D body fossil. Its type locality is Cerro Overo [MAU], which is in a Santonian levee siltstone/mudstone in the Bajo de la Carpa Formation of Argentina. It is the type species of Mahuidacursor.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Cruzado-Caballero et al. 2019 | Species as for the genus. Medium-sized ornithopod dinosaur diagnosable by the presence of dorsal ribs not distally thickened and bearing a surface restricted to the most anterolateral margin for contact to the preceding intercostal plate(potentially autapomorphic) and the following combination of synapomorphic characters:first dorsal vertebra with rectangular dorsal neural spine;first and second dorsal centra as long as the last cervical centrum; dorsal centra relatively long, and increasing in length only moderately throughout the dorsal sequence; posterior process of the coracoid scarcely developed; humerus length subequal to the scapular length; long and slender scapula; posterior end of the scapular blade narrower than the proximal end of the bone; poorly developed humeral head, rudimentary deltopectoral crest and humeral shaft strongly bowed. Differential diagnosis: Mahuidacursor differs from Macrogryphosaurus in the concave profile of the ventral side of the cervical centra in Macrogryphosaurus as well as in the proportions of the cervical centra (i.e., wider than high in Macrogryphosaurus.as wide as high in Mahuidacursor) and the neural spine of the last cervical (i.e., height significantly increasing in Macrogryphosaurus and remaining low in Mahuidacursor); it differs from Talenkauen in the humerus (i.e. the scapula length ratio, which is clearly greater in Talenkauen), in the scapula (the ratio of the distal widthof the scapular blade to the proximal width being clearly greater inTalenkauen than in Mahuidacursor), and also in the neural spine of the last cervical (i.e. Talenkauen displaying the same condition as Macrogryphosaurus); it differs and from Notohypsilophodon in the bowing of the humeral shaft, which is gentler in the latter. |
