This is a reconstruction of a skull from the achaeocete whale Basilosaurus isis, created by using CT scan data and digital retro-deformation, which reduces the effects of bone deformation over time.
By analyzing the whale’s skull as it would have existed when it was alive, paleontologists were able to see the asymmetry in the skull, that it (and many others) had a clockwise, leftward bend—that this was not a result of fossilization.
Scientists suspect this asymmetry may have helped these ancient whales hear better under water, which has led to several other evolutionary implications. Having a digital 3D model of the skull to examine made creating a reconstruction easier and more accurate. The model was printed in plaster using the Z510.
