About Isasicursor
Isasicursor (meaning "Isasi's runner" after Marcelo Pablo Isasi) is an extinct genus of elasmarian ornithopod dinosaurs known from the Late Cretaceous Chorrillo Formation of Santa Cruz Province, Argentina. The genus contains a single species, Isasicursor santacrucensis. It was a contemporary of the titanosaur sauropod Nullotitan, which was described in the same paper.
