We know about Gallimimus from the Jurassic Park franchise, but there was one ostrich-like dinosaur that was even larger than Gallimimus: Gigantoraptor! Gigantoraptor was a species of Oviraptor that stood 15 feet tall, which was five feet taller than a basketball hoop. For my upcoming dinosaur book, my fictional species of ostrich-like dinosaur will be the same size as Gigantoraptor. Imagine that flock of Gallimimus from Jurassic Park, but super-sized! Try outrunning a flock of these giants!
