A tiny assemblage
The two largest fossils in this photograph are the wing cases, or elytron, of fossil beetles. The largest is just 3.5mm long.The elytron is a thickened forewing that protects the flying wing when the beetle is on the ground. The black objects are other insect fragments, and the charcoal is the brown item (centre, bottom). The ostracod, which is a potato-shaped crustacean, is the tiny, round impression (bottom right).
