Resumen:
In the Bermejo Basin, the Los Rastros Formation is bearer of an abundant insect fauna, mainly with terrestrial adult winged organisms appertaining to Blattoptera and Coleoptera orders. The insect remains are found in the black shale from the offshore lacustrine facies. The insect taphonomic features suggest that the specimens were allochthonous to the lake. The individuals could have arrived alive to the lake and suffered a rapid fall through the water column preserving them intact, or suffered fragmentation in air transportation and by biological attack during long periods of flotation.
