Gasparinisaura had a rounded head with very large eye sockets placed high on the skull.1

Its tail had low, plate-like triangular bones called chevrons that were expanded toward the back, a feature unique among euornithopods.1

Juvenile Gasparinisaura skeletons were found with clusters of up to 140 polished stones in their bellies, which acted as a gastric mill to grind food.1

The gastroliths made up about 0.3% of the dinosaur's body weight and were about 8 millimetres across on average.1

Gasparinisaura had long hindlimbs with a short thighbone and a long lower leg, making it a fast runner.1

Its first toe bone (metatarsal) was reduced to a splint, a specialized feature for running.1
