A rare and special rock, a piece of the upper mantle was donated to the NHM by researchers of Macquarie University, Sydney, Australia. This specimen is one piece of a large collection of mantle xenoliths that is being donated to the NHM.
Most geological collections we hear about in the news are the prettiest, oldest, youngest, largest, smallest, rarest, most expensive or have some exciting story related to them that ties them to the evolution of our planet. Dinosaurs, human remains and meteorites are particularly popular. Over the last year we’ve embarked on a major curatorial project rehousing something that is the opposite – an unglamorous collection of bags of crushed rock.
