Coelurosauravus are lizard-like diapsid reptiles native to the Permian period and resembling small green iguanas or other modern day lizards. It has specialized wing-like structures allowing it to glide. These were rod like structures with skin stretched over them; this features is unique to this genus. The average length of the specimens were 60 cm and the body was long and flat, suitable for its gliding nature.

  • This is the only creature to appear in all five series of the original Primeval show.
  • Coelurosauravus is the first creature to be given a name, and one of the few creatures to actually be given one.


  • Real Coelurosauravus were only capable of gliding, but the ones in the show have powered, flapping flight.
  • The crest on Coelurosauravus' heads is speculative, and they aren't depicted with the distinctive bony frill that the real ones had.
  • It is depicted as being much larger than the real animal, which was only about as long as a human hand.
  • Rex seems to be far more intelligent and active than a primitive reptile would probably have been. However, Rex could just be an unusual specimen.
  • Rex is often shown being fed plant and fruit matter, but Coelurosauravus was probably an insectivore.
