MEDERDRA is an R4-5 rumurutite chondrite. TKW 1552 grams, and is one of the 4 known rumurutites of this subtype. It was found during a search for meteorites in Mauritania last summer. This is a breccia composed of chondrules and related clasts, showing a really beautiful matrix. I'm so proud to share this beauty with the meteor-community.
