"Terra Nova" canceled by Fox

(CBS/AP) It's official - there will be no second season of "Terra Nova" on Fox.

The network said late Monday it is dropping the pricey prehistoric drama after a single season. But there's a chance it may not go the way of the dinosaurs - Deadline reports that 20th Century Fox TV, which produced "Terra Nova," plans to shop the series to other networks.

The ambitious series, filmed in Australia with expensive special effects, got a lukewarm reception from viewers last fall despite high anticipation from sci-fi fans. It averaged less than 8 million viewers weekly.

The series followed a family on its journey back to prehistoric Earth on a mission to save the human race. It starred Jason O'Mara and Stephen Lang, with behind-the-scenes principals including Steven Spielberg.

"Terra Nova" was announced in May 2010, but production problems led to repeated delays in its debut.

Jason O'Mara declared the show's fate to his Twitter followers Monday night, tweeting:

He also sent another message thanking fans for their support:
