whats that dino noise.

Had to read Three times to get the point you're trying to make.

It's definatley the D-Rex we see in the trailer, The one that Shadows Ty.

As we can tell by the Clicking noise, It's got a mixture of Raptor and something else.

The raptors, Are believed to carry the sounds over from Prior films. 

We also hear the raptors in one of the Trailers (Can't remember if it's the leaked one or the Released one) That we hear the Raptors Shriek. Confirming that they're reusing sounds. 

It's definitely D-rex, Trevorrow and Spielberg wouldn't go through the trouble again of making new sounds for the raptors or T.rex.

On top of that, when the shadow riss over the kids face, you can see spike or quill like structures on the neck, much like the image above.

Also I wanted to say that D-rex looks (in my opinion) like a albino megaraptor on steroids. With the much larger claw and sort of middle-ground build. But that could just be me.
