The series featured human characters, a man & woman, helping an intelligent alien T-rex-like female dinosaur who may have had wings. They were on the run from someone through space. This group was possibly a galactic patrol force of some sort that one of the humans had once been a member of. There was also an Earth T-rex of normal dinosaur intelligence. I'm unsure how he was obtained but the alien T-rex still liked him, was a possibility of breeding with him as I recall. The male T-rex was kept restrained to keep him from harming the rest on the spaceship. This book was part of a series of books of which I only ever read the one, it being I think part 3 and would have been printed sometime before 1977. It seems to me the cover depicted the normal T-rex collared and chained. The winged (?) alien T-rex was there as well along with perhaps a jagged alien landscape and a spaceship. It was not Anne McCaffrey's Dinosaur planet series, Ray Bradbury's Dinosaur Tales, Harry Harrison's West of Eden or David Bischoff's Dragonstar series.

  • Hi there! That's some info already; could you please take a look at these guidelines on story-ID, see if they trigger any more memories you could edit in? Any more recollection of the plot, the covers?

  • I'll toss out "Day of the Dragonstar". First book of a three book series. amazon.com/Day-Dragonstar-Thomas-F-Monteleone-ebook/dp/…. Also, possibly the "West of Eden" series by Harry Harrison. en.wikipedia.org/wiki/West_of_Eden Commented Feb 17, 2019 at 23:29

  • Until you got talking about space, I was thinking Zelazny's Roadmarks. There was a female dragon and a cloned t-rex, and the dragon said something about liking her men being the strong silent type.

1 Answer 1


Having found an image of the book, this fits your description so I will change my comment to an answer. Although not a (long) series as far as I know, the T-Rex characters could be from The Second Experiment by J O Jeppson (Mrs Asimov). The book was published in 1974 and there was a sequel 'The Last Immortal'.

The intelligent T-Rex was an alien named Rya, guarded by a robot called Tec. The not so intelligent T-Rex was a possible mate for her, found on their travels.

    I'm a simple person. I see a winged T-Rex on a spaceship, I upvote.
