fossilized bones
Mineralized skeletal remnants
Fossilized bones are the mineralized remains of animal skeletons preserved in rock over millions of years.
The original bone material gradually replaces with minerals, turning to stone while retaining the bone's structure.
Dinosaur fossils are the most famous examples: The museum displayed fossilized bones from a Tyrannosaurus rex.
Figuratively, something fossilized is outdated or rigid: fossilized thinking.
