NEW YORK - The prehistoric drama "Terra Nova" is history on Fox.
The network said late Monday it is dropping the pricey sci-fi series after a single season.
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, "Bad news, guys. Terra Nova has been cancelled by Fox."
