Primeval attracted audiences of five million for its last series
Sci-fi drama series Primeval has been resurrected for two new series by ITV just three months after it was announced it had been axed.
Original stars including Andrew Lee Potts, Jason Fleming and Hannah Spearritt will return to the show.
The series will be co-produced by ITV and UKTV, with series four premiering on ITV and five going out first on digital channel Watch.
Primeval features a group of scientists who battle prehistoric creatures.
Series three attracted average audiences of about five million in its Saturday tea-time ITV slot.
But when ITV was forced to make drastic cuts of £40m in the channel's production budget, it looked like spelling the end of the special-effects laden series.
As part of the new deal, also part-funded by BBC Worldwide and Germany's Pro7, 13 new episodes will be split over the two series, with series four going out in early 2011.
Tim Haines, Creative Director of Impossible Picture, said: "I am thrilled that ITV has agreed to this new deal which will allow Impossible Pictures to produce another 13 episodes of Primeval.
"The confidence demonstrated in the programme's continued success here and abroad will help us bring more big screen action and a whole host of new creatures roaring back into people's living rooms."
