Plant-herbivore interactions from the Cenozoic fossil record: (A) meta-network of plant-herbivore interactions, based on 10,714 damaged leaves from 21 fossil floras; colored bars represent the total interaction frequencies of host plants and herbivores; the ten most abundant plant orders are labeled; gray lines represent pair-wise interactions, with more frequent interactions being thicker and less transparent; (B) examples of damage types: (a and b) mines mainly produced by moths; (c and d) galls mainly produced by gall midges; (e-h) external foliage feeding including hole feeding, margin feeding, surface feeding, and skeletonization; (i) endophytic oviposition; (j) in situ preservation of armored scale insects.
