Revived fossils are the remains of animals or monsters that were preserved in a petrified state. Fossils are found encased in stone or other geological deposits, but revived fossils are the freed and animated remains of the dead. They are mindless automatons that obey the orders of their evil masters.

A revived fossil does only what it is ordered to do. It can draw no conclusions of its own and takes no initiative. Because of this limitation, its instructions must always be simple, such as "Kill anyone who walks down this road." A revived fossil attacks until destroyed, for that is what it was created to do.

Revived fossils cannot be created with the animate dead spell, but instead are created through special necromantic rituals that vary depending on the fossil to be revived.

A revived fossil megaraptor uses its talons and foreclaws to shred prey.

Augmented Subtype

A creature receives this subtype whenever something happens to change its original type. Some creatures (those with an inherited template) are born with this subtype; others acquire it when they take on an acquired template. The augmented subtype is always paired with the creature's original type. For example, a wizard's raven familiar is a magical beast (augmented animal). A creature with the augmented subtype usually has the traits of its current type, but the features of its original type. For example, a wizard's raven familiar has an animal's features and the traits of a magical beast.
