“Toumai’s supporters used 3D computer reconstructions to show that the structure of the cranium had clear differences from those of gorillas and chimps and indicates that Toumai was able to walk upright on two feet”
Yeah, right. They can tell all that from the structure of the brain.
Let’s see the rest of the skeleton and then maybe it can be determined whether it walked upright or not.

Upright posture can be inferred from the location of the foramen magnum (though which the spinal cord passes).
In four-legged critters it is near the back of the skull. In critters that walk upright it is at the bottom. Take a look at a cat or dog vs. a human and you will see how this works.
