Terra Nova takes a break tonight in favor of the World Series on Fox. But, prepare yourselves, fans: executive producers René Echevarria and Brannon Braga say their show is about to hit storylines out of the park!

Following a few stand-alone installments, Echevarria and Braga go into detail below about how the sci-fi series will soon rev up its mythology. Read the full interview at EW.com and enjoy the following excerpts now...

Sixer mythology will "culminate and be explored by the end of" the 13-episode first season, Braga says. Echevarria adds: "You’re going to see who sent them here and why, and it all comes to a head in the season finale."

The show will only visit 2149 sporadically.

New dinosaurs are on the way. One is described as a "shark on legs" by Echevarria, while Braga teases: "We have the biggest dinosaur we’ve done, the biggest in the fossil record. It looks amazing. We’re also doing an ancestral Komodo dragon."

There's no guarantee of a second season, Echevarria says season one will wrap up with "kind of a cliffhanger. Everything is played out. All the elements come to a head, it’s a two-hour finale. The 11th Pilgrimage is scheduled to arrive - and who’s going to show up? The Sixer stuff gets answered and explained. We also tee up a new mystery."

Oh, one final note, the producers preview: a beloved character is going to die before the end of the season.
