Shape change comes in a variety of forms, including druid shape change, lycanthrope shape change, and the shape change spell. They vary in nature, and are not the same as polymorph (e.g. polymorph, polymorph self, monster polymorph).

Unless the ability explicitly states so, the creature does not change form upon death.¹⁾

Whether a shape-changed creature can be raised from the dead by raise dead or resurrection depends on its original form. For example, a human druid who died in giant bat form could be raised, but an elven or half-orc who died in human form could not.²⁾ When the creature is raised, it will remain in the form it died in (including wounds and poison, as normal, unless the means used to raise state otherwise).
