It was confirmed in September that a post-watershed spinoff from the ITV1 drama was in development.
The new series - subtitled New World - has been described as "older, darker and scarier" than its predecessor, with a "younger, sexier" cast.
The 13-episode run will film in Vancouver and will also be broadcast on the channel Space in Canada.
Primeval co-creator Tim Haines previously insisted that the new show will be mostly separate from the original series.
"There is a little bit of crossover [with the UK show] in the first episode, and then we'll see how it goes after that," he explained. "Mostly they'll be getting on with it themselves."
In May 2011, Primeval actor Andrew Lee Potts (Connor) told Digital Spy that he and co-star Hannah Spearritt (Abby) were unsure of their future with the programme.
"Primeval deserves to carry on, and I hope it does," he said. "As for mine and Hannah's involvement in that, we're not entirely sure."
Primeval: New World will air on Watch in late 2012.
