Segisaurus reveals the small, delicate side of the dinosaur world. This little, lightly built theropod had an elongated neck and long hind legs. It probably ate small animals, including insects, although its diet cannot be reconstructed as a complete menu.

Beyond the game
The real Segisaurus
Segisaurus lived during the Early Jurassic. It probably ate insects and other small animals, although its exact menu remains unknown.
The only known specimen was found in Tsegi Canyon, Arizona. The incomplete skeleton belongs to an animal related to Coelophysis, among the early theropods.
Its small size reminds us that dinosaur history is not only about giants. Small predators could have different roles in ecosystems, but their delicate bones are also harder to preserve and find.
