A St. Francis de Sales High School teacher on Tuesday encouraged her students to gather around a big glass box displaying a more than 100 million-year-old fossil near the entrance of a new exhibit at the Field Museum.

She asked if they noticed how the fossil almost looked like it was imprinted on a canvas as she pointed her finger at the ridges outlining a prehistoric marine creature.
