Comment on the Meteoritical Society database :

Winonaite, with O isotopes that are more 16O-rich than typical: 518O=3.57‰, S17O=1.33‰, A170=-0.53‰; many relict chondrules...

Other comments :

Unique chondrites NWA 1463 [4] and NWA 1058 may represent the regolith of the winonaite parent body. Since these specimens contain obvious chondrules, they should not be termed achondrites (despite a likely genetic relationship).
