The Venta Regional Park Visitor Centre is located in the small town of Venta in northern Lithuania. It is also the only place in the Baltic states where rocks from the Jurassic Period, which began 199 million years ago, have been naturally transported to the surface. "Here the glacier has done its job – it has dug up the valley of the Venta River and in the areas from Papilė towards Kuršėnai, where the Jurassic rocks naturally open up, we are trying to look for traces of life," Ramūnas Dulinskis, an adviser at the Venta Regional Park, told LRT.

As a result, fossils of molluscs, corals, and other marine life are found near the surface. "The Jurassic period began about 205 million years ago and lasted for about 60 million years. To enter the Jurassic climate, you would need to go into a well-watered greenhouse on a hot summer day, where the relative humidity and temperature are high," said Dulinski.
The mass extinction of animals in the preceding Triassic period led to abundant oxygen reserves, which stimulated the development of aquatic and terrestrial wildlife. "If you go to the Saltiski quarry, which contains Triassic clay, you will find practically no organic matter. You might find the remains .
