Fossil insects.
Fossils resembling modern cockroaches are known from rocks as old as the Carboniferous period (320 million years ago), when they dominated insect communities. The exact evolutionary relationships of these fossil insects with modern roaches remain unclear; they were probably distant "cousins" rather than ancestors.

Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22 to 28 in).

B. elegans lived during the late Carboniferous period, about 315 to 307 million years ago. Direct fossil preservation of leaf damage, arthropod mouthparts, and vertebrate teeth has understandably led to a focus on oral processing of plant material when considering the evolution of herbivory in deep time.
