Under the trees of Oslo's Botanical Garden, the university's Natural History Museum comprises two different museums: the Zoological Museum , which as you might guess is stuffed full of stuffed (excuse the pun) native wildlife. Adjacent to this is the Geological-Palaeontological Museum , which contains displays on the history of the solar system and Norwegian geology, as well as examples of myriad minerals, meteorites and moon rocks.
The palaeontological section includes Ida, the world's oldest complete primate fossil. In addition you can ogle a 10m-long iguanodon skeleton and a nest of dinosaur eggs. The admission fee also allows you to get green-fingered with the tropical plants inside the greenhouses.
