Quick Answer: How are fossils put together in museums?

To suspend or animate dinosaur skeletons from millions of years ago, museums create elaborate metal skeletal mounts, using either casts of bones or the original fossils. These mounts are painstakingly crafted to hold the skeletons in the desired position and protect them from potential damage, shifting or collapse.
