Fossil Preparation and Reconstruction

The video explores the discovery and preparation of the sharptooth iosaur fossil at Chicago's Field Museum. It highlights the challenges faced due to the fossil's size and the delicate process of extracting it from rock. The reconstruction involves using hand tools similar to miniature jackhammers. The video also discusses the difficulty in identifying fossil features due to the similarity in color between the fossil and the surrounding rock, which contains marine shells and snails.
