The Dalgety Downs meteorite was first discovered in 1941. A number of fragments were found scattered over a small area near a streambed. A few hundred kilograms of fragments were recovered at the time. In 1963, a second expedition located an additional 214 kilograms of fragments, and 40.9 kilograms was recovered some years later. The total known weight of the find is nearly 500 kilograms.
The interior of cut fragments shows little weathering even though the terrestial age of the meteorite was determined to be only somewhat less than 300,000 years.1 It has one of the highest terrestrial ages of any chondrite found outside of Antarctica.
