I think I have assembled the remains of some dread creature:

I'm pretty sure that I wouldn't have enough elements to reassemble this, but I would at least like to know what it looked like in it's prime.

It looks like you have SandGreen parts from probably two different sets...
The dinosaur head (x158), 2 tail sections (40396 and 40379), 2 sloped pieces (3039), and black Technic brick (3700) are likely the remains of a Baby Ankylosaurus/Young Ankylosaurus:

The wedge plate (2419) and curved brick (6091) are likely parts from a Red Planet Cruiser (also in the Alien Discovery set):
