RUN!!!

Also, this other teaser was released!  Rexy in her cage, and a new animal that is most likely the Indoraptor!

That's another duck, not an indoraptor.

^A duck?  Could you clarify my confusion?  Since when do ducks show up in Jurassic movies?

And if it's not an Indoraptor, then what is it?  It isn't the Baryonyx; it's too small, lacks the long shallow snout, and its coloration is nothing like that on the viral Jurassic World website.

I meant the Baryonyx, I just like to call them ducks for some reason.

Apparently you're right:  it is the Baryonyx.  It was confirmed in a newly-released screenshot of that exact scene today.

At 0:36 of this video, it shows it:  https://www.youtube.com/watch?v=GbzMFe8y17w
