Really nice, is it easy to split the shales.

This looks like a skull one would want to prep. It seems from your pictures the bones are mostly gone, so perhaps better to leave "shrouded". Still a beauty.

Sorry I missed this somehow, Darren. 

The shales are not easy to split, as they are very friable. My best finds have been from splitting small pieces into even smaller bits.

Thanks Michael. 

Unfortunately, the skulls are usually heavily pyritized, and difficult to prep out. The shale sticks to the pyrite and makes for a tough job.

Is that we can prep ny acid or sand blaster? have you tried them before?

@vietnamfossil

The air abrasives can work, but, I have not tried acid.
