Encounter the oldest bird to ever be discovered! Beautifully preserved specimens ranging from the wings of a giant dragonfly, shrimp & crabs, to lizards & flying pterosaurs! No other locale has produced more iconic fossils from this time period than the Solnhofen Limestone, and Rockford's own Burpee Museum will display the most unique of the collection!
