The skeleton of the conventional shrew Crocidura nyansae compared to the bewildering Hero Shrew, Scutisorex somereni. The skull is also unusually robust but, for whatever reason, the limbs are totally unremarkable.

The Hero Shrew (Scutisorex somereni) also has some odd musculature, most notably, the transverse spinalis muscles are highly reduced and appear to have been replaced in their function (resisting torsion and sheer) by the numerous interlocking tubercles.

Lots and lots of lamnoid shark skulls. Note the extreme, derived skulls (well, chondrocrania) of the Megamouth Shark (Megachasma pelagios), Basking Shark (Cetorhinus maximus) and Goblin Shark (Mitsukurina owstoni).
