Young on the left, much older on the right. Crocodilians keep growing well into old age, and as they do the skull gets heavier, the surface gets rougher, and the teeth end up spaced further apart.

Every rodent's incisors grow for its whole life. They are supposed to grind against each other and stay filed down.

When the bite is off, nothing files anything, and the teeth just keep going. This woodchuck's ended up curving out past the muzzle like tusks.

A gharial skull is mostly snout, and that is the entire point. Long, thin and light means it can be swept sideways through water faster than a fish can get out of the way.

The teeth are shaped to hold, not to crush. A broad-snouted crocodile has the opposite problem and, unsurprisingly, the opposite skull.

This is an emu's synsacrum, held up for scale.

Nearly all of it is one bone: the lower spine, the hips and the sacrum fused into a single rigid piece instead of a stack of separate joints.

Birds have one. So did some dinosaurs and pterosaurs, and so do xenarthran mammals, the group that includes armadillos and sloths.
