Gasparinisaura (meaning “Gasparini’s lizard”) is a genus of herbivorous ornithopod dinosaur from the Late Cretaceous.
The first fossils of Gasparinisaura were in 1992 found in Argentina, near Cinco Saltos in Río Negro Province. Gasparinisaura was a small bipedal herbivore.
Gasparinisaura had a rounded head that was moderately elongated. The eye sockets were very large and placed in a high position. The rather long back of the head was pendant. The jugal had a front branch that was thin and wedged between the maxilla and the lacrimal; the back of the jugal was high and broad. The quadratojugal had a long ascending process touching the squamosal, a basal trait. The jaw joints were low. There were about twelve, rather large, maxillary or dentary teeth in each upper or lower jaw. The forelimbs were lightly built. The ilium was short and low, the pubis thin. The hindlimbs were relatively long and powerful, with a short thighbone and a long lower leg. The foot was long and the first metatarsal was reduced to a splint, a derived trait. The tail featured low plate-like triangular chevrons that were expanded towards the back, which is unique in the Euornithopoda.
The gastroliths discovered formed clusters of up to hundred-forty rounded and polished stones in the abdomen with an average stone diameter of about eight millimeters. Representing about 0.3% of total body weight, they were voluminous enough to function as a gastric mill, a function sometimes denied for sauropod gastroliths because of their insufficient relative mass, being an order of magnitude lower.
