45027 Cosquer           Discovered 1999 Nov. 28 by S. Sposetti at Gnosca.
Henri Cosquer (b. 1950) is a professional diver who in 1985 discovered the cave now named for him near Marseilles. On the walls of the cave are ancient paintings dating back 27~000 and 19~000 years. The cave entrance is 37 meters under the actual Mediterranean sea level. The name was suggested by G. Burki.
