Santonian cockroaches from Yantardakh amber (Russia: Taimyr) differ in dominance
Cretaceous amber cockroaches are known only from Lebanon, Myanmar and France. An assemblage of 14 dictyopterans (2 unidentified) from Santonian amber of Yantardakh, Taimyr, Russia is reported here, comprising only 0.3 % of ˃5,000 collected insects. Small pieces (0.03–0.30 g) contain six immature ind...
