Bouanane 31°59'N, 3°12'W
Morocco
Found: 2009
Classification: Ordinary chondrite (L6)
History: P. Thomas (St-André en Vivarais France) acquired this stone and visited the camp site to take GPS coordinates.
Physical characteristics: A single stone showing fusion crust on 20% of its surface but obvious signs of repeated hammering on its edges plus a central hole made by percussion. Identified by a specialist of lithic tools (H. de Lumley, MNHNP) as a hammer and anvil of probable Neolithic age.
Petrography: WS was determined on a 3 cm deep core but seems quite homogeneous, supporting, together with surface state, a rather young terrestrial age unless Neolithic use was followed by sheltering preventing atmospheric alteration.
