3D models of scanned objects can be modified in any way conceivable, and I have been playing around with the scanned parts of Bernie's skull to re-create a full skull with missing parts. I've been using Rhino software to do it, which is available for a 90 day evaluation period free of charge. It's really good software but I don't think I can justify purchasing a real copy when my 90 day period is up. So I'll just have to work fast, I guess!
Here's some screen captures of the process I've gone through. I have modeled the back art of the skull, currently missing, as an Ichthyosaur skull without temporal fenestras. It is easier that way, and seems to fit the back end projections better. In some ways the resultant skull resembles a cross between Ichthyosaurs and large Amphibians such as Temnospondyls. This may not be real, but until we get more loose bones we don't know for sure what it looked like. If it has temporal fenestras like other Thalattosaurs, the skull and mandible would be even longer than in this recreation.
So here's the process in pictures: Here is four views of the original half-skull scan.
