Dinosaur
Terragen formerly extinct Mesozoic archosaurian reptile. Most of the well-known species have been lazurogened with a greater or lesser faithfulness to paleontological authenticity. A large number of dinosaurs and other mesozoic species can be found on the surface of the terraformed and mesozoiformed planet Owen.
A large number of dinosaur species have also been provolved, and many of these live in the Archosaurian Empire.
