Isasicursor is the youngest known ornithopod from the Southern Hemisphere, meaning it lived very late in the Age of Dinosaurs.1

Its fossils were found together with bones of young and old individuals, which scientists think means Isasicursor may have lived in herds.1

The first bone of Isasicursor was discovered by technician Marcelo Pablo Isasi, who the dinosaur is named after.1

Isasicursor had a special pin-and-hole connection between its first and second sacral vertebrae, which is unique among dinosaurs.1

It lived alongside the giant titanosaur Nullotitan, and the two probably ate different plants so they did not compete.1

Isasicursor was probably hunted by the huge megaraptorid Maip and the crocodile-like Kostensuchus.1
