Have you ever wondered what happens to dinosaur fossils after paleontologists dig them up?

They don't only go on display in museums. Scientists also investigate those fossilized remains to learn more about how dinosaurs’ bodies functioned and how they lived. And thanks to new and improved technologies—from pressure sensors to computer models, lidar scanning to laser-simulated fluorescence—they’re making exciting new discoveries about these fascinating creatures.

Scientists’ questions include: What did dinosaurs look like? How did they move and hunt? Did they protect and care for their young?
