- The maximum wingspan of dragonflies these days is about 19 cm, but in the Late Palaeozoic (approximately 300 Mya), the largest representatives of the Meganeuridae family had a wingspan of about 71 cm. They were thus the largest known insects ever and previously there were already some hypotheses, based on (unfortunately often incomplete) fossil findings and on comparisons with modern-day species, about how these flying colossuses lived. However, an international French-Czech-US team, together with Jakub Prokop and Martina Pecharová from the Department of Zoology of the Faculty of Science, showed that these speculations were not correct and proposed a more probable scenario.
