The ecology of Paleozoic terrestrial arthropods: the fossil evidence

TL;DR: It is postulated that herbivory, defined as predation on living plants, may have been rare in early Paleozoic terrestrial ecosystems, and that most primary productivity of terrestrial arthropods was diverted into higher trophic levels.
