Zephyrosaurus was a small dinosaur. It was a relative of Hypsilophodon. It lived 132 million years ago, in the western part of what is now North America. It was 6 ft (2 metres) long and 3 ft (1 metre) high.

The remains are bones from various parts of the body. It had a steep face, a raised knob on the upper jaw, and a larger knob on the cheekbone. Some of the bones may have allowed movement within the skull (cranial kinesis) as well. Like other hypsilophodonts, it had beak teeth.^[1]^[2]
