Fossil preparation and restorationist Lauren McClain works on a mosasaur jaw in Houston, Texas, on April 30, 2024. Before a T. rex can tower over museum visitors or a Triceratops can show off its huge horns, dinosaur fossils must first be painstakingly reconstructed -- cleaned, fit together and even painted. McClain's job begins at her home workshop where she carefully clears away dirt stuck to the more than 60-million-year-old remains using a tiny drill with an air compressor, similar to a dentist's tool.
