Rochecouart, a giant meteorite crater in France. Superb shatter cone, from an old collection, showing the so-called percussion cones (also ponytail structure). These characteristic marks are the result of a mega meteorite impact (in the form of an asteroid) whose crater, now largely eroded, is located in the Limousin.

The shatter cones are the witnesses of this event which was a real local cataclysm Height 180 mm Width 120 mm Thickness 90 mm for 2,4 kg
