Abstract

original image

In one ear … : The outer shape and inner architecture of individual particles of a complex calcite–gelatine composite resemble the known characteristics of biogenic otoconia (“ear dust”; see picture). The relationships between the morphology of artificial and biogenic specimens are discussed.
