It's not EXACTLY like Primeval in the sense of dinosaurs being mixed with time travel, but I really liked Dinosaur Planet by Anne McCaffrey. This was before she became synonymous with her work on the Pern series, which is a real pity as Dinosaur Planet was such a neat idea. The book is about space travels who go to this planet in the hopes of mining it for precious materials, but instead discovers that it is home to a bunch of dinosaurs. The story also features some mutineers, but it was the dinosaurs that stood out the most for me.

I remember Primeval, it was a show about "temporal anomalies" that allowed time travel. It was very much a "monster of the week" kind of show where the monsters were dinosaurs. The CGI was a bit ropey, but the show was enjoyable enough for what it was. The most obvious novel to suggest would be Jurassic Park, but chances are you've already seen the movie and read the books by now as it is very popular. A lesser known book I would suggest is the "Thunder" series by James F. David. It's a trilogy of books about what happens when the boundaries of time basically dissolves and causes everything to collide. It's got dinosaurs stalking the streets, cities being replaced by prehistoric jungles etc.

I actually read a book about dinosaurs very recently and while I haven't watched the television series that you are talking about, I think you might enjoy it. The book is called End of an Era and the author is Robert Sawyer. It's about this paleontologist who wants to know what really killed the dinosaurs and makes use of an experimental time travelling device to go found out. What the paleontologist and his partner who accompanies him did not expect was to find that there is a war going on! Despite going back to the Cretaceious period, the two humans discover that dinosaurs are not the only live on earth, but that Martians are also wreaking havoc. These Martians are actually using the dinosaurs as pawns, which I know sounds like b-movie schlock, but the story is actually very good.
