The special exhibition DINOSAURIER-EIER displays unique fossils, including eggs of long-necked dinosaurs, the clutch of a duck-billed dinosaur and several clutches of bird-like predatory dinosaurs. They come from three continents: South America, Asia, and Europe. Compared to their size, dinosaurs laid rather small eggs. For example, the eggs of the herbivorous long-necked dinosaurs were at most the size of a soccer ball. Also, their shapes and surfaces of fossil dinosaur eggs differ from those of their modern present-day representatives, the birds. The fossilized eggs offer interesting insights into life millions of years ago, such as nesting behavior and the evolutionary advantages of different egg forms.
