Archaeopteryx (a bird and so a theropod dinosaur) had the small jaws and sharp teeth characteristic of living insect-eaters. These are useful for piercing tough exoskeletons of insects but can also be used to catch small lizards, fish and mammals. This is why it is hard to tell the difference between a true insect-eater and a small flesh-eater from fossils.
