Fungus gnat entombed in a 40-million-year-old piece of amber is a rare gem

A Danish amber collector's find upon a wild North Sea shore in the 1960's has proved to be of great and surprising significance. After having thoroughly examined the roughly 40-million-year-old piece of amber, University of Copenhagen researchers have discovered it to contain the first fossil of a predatory fungus gnat belonging to a rare genus. The research contributes new knowledge about the distribution of the gnat species and about biodiversity across space and time.
