Discovered in Antarctica in 2008, Trinisaura is the first identified ornithopod from this massive continent, and one of the few to be named after the female of the species (another is the very similar Leaellynasaura , from Australia). What makes Trinisaura important is that it inhabited an unusually harsh landscape by Mesozoic standards; 70 million years ago, Antarctica wasn't nearly as frigid as it is today, but it was still plunged in darkness for much of the year. Like other dinosaurs from Australia and Antarctica, Trinisaura adapted to its environment by evolving unusually large eyes, which helped it to gather in sparse sunlight and spot voracious theropods from a healthy distance away.
