— A small (150 × 200‐μm‐size) clast consisting of 20 vol.% olivine microchondrules (with barred and granular textures) and 80 vol.% recrystallized silicate matrix material occurs in Krymka (LL3.1). This is the fourth microchondrule‐bearing clast to be described. The chondrules are zoned in FeO with concentrations increasing toward the surface. The clast most closely resembles a previously described radial‐pyroxene‐microchondrule‐bearing clast in Piancaldoli (LL3.4).
