The most specialized associations, which were diverse and abundant during the latest Cretaceous, almost disappeared at the boundary and failed to recover in younger strata even while generalized associations regained their Cretaceous abundances. These results are consistent with a sudden ecological perturbation that precipitated a diversity bottleneck for insects and plants.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380013170131013504","@type":"Researcher","foaf:name":[{"@value":"Conrad C.
