Amtjärnsbrottet is a closed limestone quarry north of Rättvik. Here are the fossils at the center, including sea lilies whose stems can be seen on the walls of the crime. The area is a great natural experience with black edged layers of clay and alum slate surrounded by dense spruce forest.
Description
Geology
At Amtjärnsbrottet you can see rock layers that were thrown vertically by the force of the meteorite strike that created the Siljansringen 377 million years ago. Here, among other things, there are remains of sea lilies, crystal apples and armpits.
The southern part of Amtjärnsbrottet is kept open to facilitate studies of the quarry's walls. The limestone wall of the reef limestone in the west is of the Kullsberg limestone type. If you go near the wall you will see that it contains a very large amount of fossils in the form of long narrow, pipe-like stalks of sea lilies (crinoids).
