Known from a single specimen--which was found in a curled-up posture, either because it was sleeping or because it was huddling to protect itself from the elements--Sinornithoides was a small, agile, feathered theropod that resembled a (much) smaller version of the more famous Troodon. Like other troodonts, as they're called, the early Cretaceous Sinornithoides probably feasted on a large selection of prey, ranging from insects to lizards to its fellow dinosaurs.
