Apple today released a brand-new teaser trailer for Carlos Saldanha's upcoming sequel "Ice Age: Dawn of the Dinosaurs," which marks the return of Sid, Ellie, Diego, Manny, and of course, Scrat. This third installment in the popular series is scheduled to open July 1, 2009.

As usual, this new preview features another one of Scrat's desperate attempts to protect his beloved acorn, and as usua, it's quite hilarious. While I'm not a huge "Ice Age" fan, I do admit Scrat's segments throughout the movies definitely make me laugh.

Sit back and enjoy poor Scrat's latest misfortune right after the jump. Do you already have the "Ice Age" fever?
