What can be seen at the university's museum in Our Town?
There are "unique fossils" on display in the museum.
Professor Willard is invited to speak directly to the audience in the first act to give a few brief notes about Grover's Corners. He speaks about the geological facts of the area and says that some unique fossils have been found "two miles out of town, in Silas Peckham's cow pasture".
These fossils are on display in the university museum.
When the professor asks if he should go on and provide more details about the town's meteorological situation, the Stage Manager politely suggests that there is no more time for such information.
