A new paoliid genus and species, Permomertovia simpliciradius, and a new grylloblattid species, Oborella monsjovisensis, are described from the Early Permian (Lower Rotliegend) of Sitters and Niedermoschel in the Saar-Nahe Basin, Germany. These discoveries increase the insect diversity documented from the Niedermoschel black shale and furthermore confirm the high diversity of Paoliidae in Central Europe during this period.

A new genus and species, Glanomerope virgoferroa gen. et sp. nov., the first Permian record of a scorpionfly from Germany, is described from the Niedermoschel black shale, Meisenheim Formation, Lower Rotliegend of the Saar-Nahe basin. It is assigned to the Protomeropidae, the oldest known family of the holometabolous superorder Panorpida, ranging from the Bashkirian-Moscovian (Late Carboniferous) to the Roadian. It confirms that this family was very diverse in Central Europe during the Early Permian. Protomeropidae possibly became extinct in the course of major climatic changes that progressively affected the supercontinent Pangea after the Artinskian, although generally these changes seem to have more severely affected some other insects such as the palaeopteran Dictyoneuridae than holometabolous groups.

Vertebrate trace fossils are reported for the first time from red beds near the top of megacyclic sequence II at Prim Point in southwestern Prince Edward Island. They occur as casts of tetrapod trackways. The ichnocoenose also includes a rich invertebrate ichnofauna. The trackmakers thrived in an area of sparse vegetation and occupied out-of-channel river sediments, most likely crevasse-splay deposits.Amphisauropus latus, represented by three trackways, has been previously reported from Germany, Poland, and Czechoslovakia. It is here interpreted as the track of a cotylosaur. It occurs together with the track of Gilmoreichnus kablikae, which is either a captorhinomorph or possibly a juvenile pelycosaur. These facilitate the assignment of a late Early Permian (late Autunian) age to the strata. The third set of footprints, those of a small herbivorous pelycosaur, compare most closely with Ichniotherium willsi, known hitherto from the Keele beds (latest Stephanian) of the English Midlands.This ichnocoenose occurs in a plate-tectonically rafted segment of crust stratigraphically equivalent to the same association of ichnofauna in the English Midlands and central Europe. The community occupied piedmont-valley-flat red beds within the molasse facies of Variscan uplands.

Abstract Thirty-five radiolarian species, belonging to two assemblages, one from the Changhsingian and the second one from the early Anisian, were recovered from siliceous rocks occurring in Xijirulan orogenic belt, northern Tibet. A new radiolarian species of them, Cryptostephanidium tibetensis, is described. The lower Anisian Eptingium nakasekoi assemblage co-occurs with conodonts belonging to Chiosella timorensis Zone. This fact allows correlation between radiolarian and conodont biozones. The lower Anisian radiolarian assemblage has a high diversity and supports that radiolarian radiation after the end-Permian mass extinction begins in the earliest Anisian. The research on the lithostratigraphic sequence and sedimentology shows that the old land of the Xijirulan orogenic belt, formed by the collision between the Qiangtang and Koh Xil terranes at the latest Early Permian, has disappeared in the early Changhsingian. During the Changhsingian and Triassic, the Xijirulan orogenic belt has become a deep marine basin and was combined with the Bayan Har Basin. This large deep sea basin extended until the end of the Triassic, locally possibly until the Jurassic.
