       This meteorite fell near Ibitira in the state of Minas Gerais, Brazil on 30 June 1957 between 5:00 and 5:30 local time.  It was found in a hole 25cm deep and 20cm in diameter.    Ibitira is a unique eucrite - it is unbrecciated, displays an unusual vesicular texture, and appears to be one of the oldest eucrites ever found.   "Ibitira also has an oxygen isotopic composition, alkali element contents, and a Ti/Hf ratio that distinguish it from basaltic eucrites. These differences support derivation from a distinct parent asteroid. Thus, Ibitira is the first recognized representative of the fifth known asteroidal basaltic crust, the others being the HED, mesosiderite, angrite, and NWA 011 parent asteroids." Mittlefehldt, David W. Ibitira: A basaltic achondrite from a distinct parent asteroid and implications for the Dawn mission  May 2005.

     A single stone of about 2.5kg was found.  Classified as an achondrite basaltic eucrite.  Not only unique looking with strings of vesicals but rare as well.
