This image shows the proportion of described insect occurrences that belong to Palaeodictyopteroidea and other paleopterous groups (i.e., those more closely related to Ephemeroptera and Odonata) at each of the konzentrat Lagerstätten that are over 200 million years old. The konzentrat Lagerstätten are arranged from oldest to youngest. All data are from the Paleobiology Database and were compiled primarily by Matthew Clapham.
