Ana Balcarcel's job is to carve the fossilized bones of ancient creatures out of rocks. Every day, she works with animals who haven't seen the light of day for millions of years. Welcome to the paleontology prep lab.

In this video, the second in a series of interviews io9 is doing with the scientists and researchers at New York's American Museum of Natural History, Balcarcel shows us where fossils come from. And we see the tools she uses to bring these long-extinct creatures back to (skeletal) life.

This interview was conducted by Gaby Darbyshire, and directed by Matt Toder. Many thanks to the AMNH. Look for our other videos in the Hardcore Science Interview series, and visit the AMNH to see their new exhibit, "World's Largest Dinosaurs."
