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.

"Ruling Reptile". Important biological clade of terragen vertebrates that rose to prominence in the Mesozoic of Old Earth. It includes crocodilians, dinosaurs, birds, and a number of other extant, extinct or lazurogened types. A number of provolved species are of archosaurian derivation.
- Dorrahsa - Text by M. Alan Kazlev
A race of small dinosaur provolves, the Dorrahsa spread widely during the early Empires period. Only one clade of Dorrahsa were settled on Owen, where they have reverted to a primitive culture. Those that are distributed through space are generally more intelligent, technologically savvy, and assimilate well into hu culture (mainly as companion sentients), although a few clades have a predilection for violent employment (mercenaries and piracy are common occupations, but only in conjunction with other races).
