Executive producer David Fury is no longer attached to Fox's time travel epic "Terra Nova." No replacement for Fury was named leaving showrunner Brandon Braga as the sole writing executive producer.
A representative for 20th Century Fox Television confirmed the details of Fury's exit.
"Terra Nova," which stars Jason O'Mara as the patriarch of a family who travels to the ancient world in order to save humanity, is also being executive produced by Steven Spielberg and Peter Chernin.
Fury has worked as an executive producer on several other series including "24," "Lost" and "Buffy The Vampire Slayer."
"Terra Nova" is being produced for Fox by Amblin Entertainment and Chernin Entertainment. Fox will air a preview of the show in May 2011 before it debuts next fall.
