Skalka u Velimi, Nature reserve near Velim, Czech Republic.

Skalka u Velimi is a former amphibolite quarry near Velim, now a nature reserve. The pit is partly flooded and partly used as a gravel storage yard and crushing plant. The site is known for an exceptionally rich deposit of Cretaceous marine fauna with rare preservation.

The area was officially protected in 1987 to preserve its geological record from the Cretaceous period, roughly 100 million years ago. The rock layers document a time when this region lay beneath a shallow sea teeming with marine life.

The site draws researchers interested in studying preserved remains of ancient marine creatures found within the rock layers. Visitors walking through the area can observe how this location serves as a natural archive of prehistoric life.

Access to the reserve is easy from the main road through a short walking path, and parking is available near the entrance. Wear sturdy shoes and use caution if the ground is wet, as paths around the water can become slippery.

The quarry is not limestone but amphibolite, and the protected site is known for an exceptionally rich deposit of Mesozoic marine fauna with rare preservation. Part of the pit is now flooded, while another part serves as a gravel dump and crushing plant.
