Amber with insects

                 Inclusions                                                                       

Tree resins were very fluid and solidified very quickly through evaporation. A little fly or ant caught by the sticky resin remained trapped for centuries, this is how inclusions were formed. About 3 thousand representatives of fossil fauna have been found in amber, 10-15% of which are presently existing species of insects that have not evolved much since.
Most common inclusions are insects (86,7%) and Arachnids (11,6%), while animals of other classes occur only in 1,7% and plants in 0,4% of cases.
