Even with sophisticated software, the reconstruction required expert anatomical knowledge.

Many fragments are featureless chips where the distinguishing landmarks have been lost to damage or erosion.

Deciding where those fragments belong requires understanding what the intact skull should look like, and making judgment calls about where ambiguous pieces fit.

The reconstruction is therefore not a simple jigsaw puzzle with a single correct solution.

It is a scientific interpretation of fragmentary evidence, constrained by anatomy but not determined by it in every detail.

Different researchers working with the same fragments might produce reconstructions that differ in minor ways.
