Classification: HED achondrite (Eucrite, melt breccia)

History: The meteorite (4 pieces totaling 2400 g) was found August 30, 2020, in the Bordj Omar Driss area (State Illizi, Algeria) and 2 pieces totaling 1150 g were purchased from a meteorite dealer in Mauritania.

Physical characteristics: Dark-grayish rock with some light clasts and pores.
