An artificial outcrop of the Jurassic geological period is located at Papartynė. The Jurassic period is the middle period of the Mesozoic Era, a period of Earth development beginning 205 million years ago and ending 145 million years ago. The Jurassic period was warm and humid. Characteristic vegetation included ferns and gymnospermous. But it is best known to everyone as the period of the emergence and development of giant reptiles (dinosaurs). That was the period when flying reptiles and first birds appeared. Belemnites were the main food of aquatic dinosaurs – ichthyosaurs. At the end of the Jurassic period, the first angiospermae appeared.
