Jawbone both visually and in name is clearly the head of the four part Rock Lords combiner Fossilsaurus. Tonka had intended to release these four figures as 'Fossil Lords'.
This Fossil Lord suffers least from I'm part of a combiner syndrome. Yes it has a huge head as a body, however there's many other characters with this motif that aren't part of something else. Jawbone has shoulder and hip articulation with bending knees, albeit backwards and a nodding head, all making it a play-with-able action figure in its own right. For a combiner part, there's no glaring downside to Jawbone.
While all four figures saw late in development design changes, Jawbone's humanoid form didn't suffer as a result bar issues with holding the gun.
Weird Weapons Jawbone can hold his huge weapon but only with the arm raised and can't lower it any further than shown below. The two Y angled handles on the back of the weapon can't be used and the forward grip is a mystery. His counterpart Ribcage's instruction indicate the extra handle on its weapon is used for carrying it, however it's not mentioned for Jawbone. This would only be necessary because there's no way to lower the arm holding it by the main grip. Oddly, the prototype weapons did work fine for the prototype figures. During late redesign it feels as if the weapon and figure modifications were out of sync or maybe planned something that didn't eventuate; see prototype below.
Name While the character's English name is not shown on the packaging or instructions, Jawbone is printed both with and without the space in various marketing material.
As with the other three Fossil Lords, Jawbone was only sold as a combined set and not individually as Monsterous and Puzzler's parts were.

Prototype The production version of Jawbone saw the opening jaw mechanism removed as well as the shoulders simplified as they no longer needed to lower the hands into Ribcage's now removed chest indents; see below.
