Gasparinisaura Dinosaur is an extinct genus of dinosaur from the Late Cretaceous period, approximately 70 million years ago. It was a small to medium sized ornithopod, which belonged to the family of Dryosauridae. Fossil remains of Gasparinisaura have been found in the area now known as the Candelero Formation in Patagonia, Argentina. The Gasparinisaura was first described in 2000 by Zulma Gasparini and a team of Argentine paleontologists. The genus name honors Gasparini for her contributions to dinosaur research. The type species is Gasparinisaura cincosaltensis, which is derived from its location in the Salado Basin and the Latin meaning of five.
Approximately 114 bones representing four individuals were discovered. From these remains it is estimated that Gasparinisaura reached a maximum length of about 2.1 meters and had a weight of around 80 kilograms. It had a curved snout and large orbits. It possessed five maxillary teeth, a long, narrow dentary with teeth bearing ridges that widen toward the tooth crown, three or four cervical vertebrae, and osteoderms on the back and neck. Gasparinisaura was bipedal, meaning its back legs were larger and stronger than its front legs. This would have allowed it to run quickly. It likely used its tail for balance while running. The short arms were probably used for grasping food and for defense. The teeth indicate it was an omnivore, eating both plants and small animals.

Based on its anatomy, Gasparinisaura has been placed into the suborder Ornithopoda, a group of plant-eating, bird-hipped dinosaurs. It was part of the iguanodontian group of dinosaurs, which includes modern animals such as birds, crocodiles, and lizards. The exact evolutionary relationships of Gasparinisaura to other ornithopods is not yet clear. However, its features and location suggest it could be a close relative to the Clade Megaheterodontosauridae, a group of ornithopods that includes the genera Muyelensaurus and Huinculsaurus.
Gasparinisaura is unique among iguanodontians because its skull is more similar to Dryosaurids than other iguanodontids. It also has a relatively long snout, which is an adaptation for browsing; indicating Gasparinisaura ate both plants and animals. Gasparinisaura lived in what is now South America during the Late Cretaceous period, about 70 million years ago. During this period, South America was home to a wide variety of dinosaurs, such as the titanosaurid Argentinosaurus, the large therapod Mapusaurus, and the small ornithomimosaur Harpymimus.
