       Trinisaura was a fairly small ornithopod dinosaur that lived in Antarctica back before it became covered by snow and ice.‭ ‬Not that much can be inferred about the lifestyle of Trinisaura due to lack of more complete remains,‭ ‬but as a small ornithopod it probably roamed around‭ ‬on just its rear legs as it browsed upon vegetation,‭ ‬while relying upon speed and agility to escape predators.‭ ‬Trinisaura probably shared its habitat with the armoured nodosaur Antarctopelta which is also known from the same approximate time and area.
