Silverstri （1912） described two genera and eight species of Machilidae or Machiloidae incertae sedis from Baltic amber （35-40 Myr）. In Cretaceous Myanmar amber （burmite： -99 Myr） one preserved Machilidae plus five undetermined specimens were reported but with no details by Grimaldi et al. （2002）. In Dominican amber （20-25 Myr） only Neomachilellus （Praeneomachilellus） dominicanus （Sturm ＆ Poinar 1997： Meinertellidae） has been found. Mendes （2013） considered that one undetermined Microcoryphia specimen preserved in burmite belonged to the genus Macropsontus, but did not provide enough argumentation.展开更多

They were confirmed by dinosaur experts from the Zhejiang Museum of Natural History to be those of Mesozoic herbivorous dinosaurs （Fig. 1）. Not long before, Yiwu Museum staff had discovered dinosaur eggs close by this place.展开更多

This paper reports a significant evidence of insect oviposition on plant leaf from the middle Jurassic for the first time. The ovipositional scar is distributed on the abaxial surface of Sphenobaiera leaf（Ginkgoales） from the middle Jurassic Daohugou Formation of Inner Mongolia, China. A new ichnospecies Paleoovoidus venustus sp. nov. is described. The scar is elliptic to oval, arranged in longitudinal rows between leaf veins with almost regular distance, with its long axis paralleling to the leaf venation. This discovery adds new information to the morphology of insect endophytic oviposition probably produced by Odonata existed in a terrestrial ecosystem ~165 Ma ago. The new materials also provide important data for the study of insect reproductive biology, plant-insect interaction and coevolution, as well as understanding the paleoclimate and palaeoenvironment during that time in northeast China.展开更多
