FIGURES 49–51 in A revision and addition to Zopheridae (Coleoptera: Tenebrionoidea) in Baltic amber: possible connections between modern Holarctic distributions and Eocene 'amber forests'

FIGURES 49–51. Baltic amber zopherid assemblage affinities compared to Recent faunas (Mediterranean, Eastern Asia, West Nearctic, and East Nearctic): 49—North polar views of the Earth in late Eocene (38 Ma) modified from Markwick (2007); 50– 51—North polar view in Recent. The "amber (succinite) zone in Eocene" ring is induced from the amber deposits mainly known from the late Eocene of Europe; the "zopherid relicts zone in Recent" ring marks the analogous territory where all Eocene zopherid genera that have survived since the Eocene currently occur. Numbers indicate quantity of known genera in Baltic amber (black circle in yellow area of the Eocene succinite outcrops) and genera of this assemblage preserved in corresponding regions at the present (white circles).
