Millbillillie
A 175 grams (6.2 oz) individual of the Millbillillie meteorite shower, a eucrite achondrite that fell in Western Australia in 1960. This specimen is approx. 6 centimetres (2.4 in) wide. Note the shiny black fusion crust with flow lines. The chip at lower right allows one to see the light-gray interior. The orange staining at top is a result of weathering, as these stones were not recovered until many years after they fell.

History

edit
 
21.78 grams (0.768 oz) complete specimen.

A fireball was observed "with sparks coming off it" by two stationworkers while they were opening a gate in the boundary fence on a track between Millbillillie and Jundee cattle stations.[1] The object fell on a plain to the north.[1] No search was made at the time but in 1970 and 1971 locals found two stones; Aboriginals have found others since.[1] The largest stone weighed 20 kilograms (44 lb).[1] It and a smaller one of 565 grams (19.9 oz) are held by the Western Australian Museum.[1]
