Kumarembia hurleyi Engel & Grimaldi, gen. n. et sp. n., is described, figured, and distinguished from other archembioid genera. The genus shares male genitalic features with scelembiids, otherwi...
متن کاملPermian ancestors of Hymenoptera and Raphidioptera
The origin of Hymenoptera remains controversial. Currently accepted hypotheses consider Hymenoptera as the first side branch of Holometabola or sister-group to Mecopteroidea. In contrast, fossils confirm the idea of Martynov that Hymenoptera are related to Megaloptera and Raphidioptera. Hymenoptera have descended along with Raphidioptera from the earliest Megaloptera, the Permian Parasialidae. ...
متن کاملPERMIAN-TRIASSIC BOUNDARY OF INDIAN SUBCONTINENT AND ITS INTERCONTINENTAL CORRELATION

The deposition of the Kuling Shales and their equivalents in different parts of the Himalayas was followed by shallowing and regression of the sea. Sedimentation was interrupted at the t...

متن کاملThe Permian–Triassic boundary in Antarctica
The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...
