5.7g fragment sold in a membrane box with a label.   I suggest not to open the membrane box as the stone is extremely friable.

Stevns Klint is a geological site that illustrates the impact of an asteroid that created the global mass extinction of species some 65 million years ago, known as the Chicxulub event.

These cliffs show high-quality exposure of the Cretaceous-Tertiary (K/T) boundary section: the border is visible as a reddish layer in the strata. In 1980, a scientific team started to study the fish clay at Stevns Klint and found large traces of iridium, commonly found in cosmic material. This gave rise to a new theory that mass extinction wasn’t caused by extensive volcanism in India, but was due to the impact of a giant asteroid.

The cliffs of Stevns Klint are also rich in fossils. There is a significant fossil record before and after the K/T boundary layer.
