Cratopetalura petruleviciusi gen. et sp. nov. is the third genus and species of the Mesozoic petalurid family Cretapetaluridae from the Lower Cretaceous of Brazil. With the recent discovery of another representative of this family in the Lower Cretaceous of England, it demonstrates the great diversity of this group during this period.
The fossil dragonfly Eumorbaeschna adriankini sp. nov. is decribed as first fossil insect from the Upper Jurassic of Central Poland (Owadów−Brzezinki quarry, Tomaszów Mazowiecki area), and as first record of the family Eumor− baeschnidae (Odonata, Anisoptera, Aeshnoptera) outside the Solnhofen lithographic limestone.
