Try to imagine. You are 430 million years back in time near St. Jana pod Skalou and dive in the sea. You see the seabed rising and the volcanoes penetrating it. Volcanoes spewing ash into a wide area as they explode. And near this ferocious rampage, two Miraspis mira trilobites swim.

It is not easy to prepare and properly store long snake bodies in collections. In the past, large cylinders with ground-glass lids served this purpose. Today we use more accessible containers with metal and plastic closures. The lids must be well sealed because the snakes inside are in 70% alcohol.
Zoological collections also contain a significant number of specimens of complete animal skeletons, which can either be unfolded and stored in boxes or folded. Do you recognize the animals in the picture?
