Eight species of conodonts, assigned to five genera, are described from the Zechstein limestone horizon of the Werra cyclothem from Wejherowo I.G.-1 boring in Pomerania. Lonchodina vistulensis n.sp., Prioniodina lindstroemi n.sp. and Hibbardella baltica n.sp. have been erected as new species. The Zechstein conodonts have been compared with the conodonts being parts of so-called natural assemblages.

Partially preserved temnospondyl mandibles from the Late Permian–Early Triassic Buena Vista Formation of Uruguay are referred to the basal stereospondyl taxon Mastodonsauridae. These represent the earliest known members of this group for South America. In most cases, this assignment was based on the characteristic morphology of the postglenoid (= postarticular) area of the lower jaw together with the presence of a hamate process. Comparisons with basal mastodonsaurids indicate that the Uruguayan specimens are phenetically similar to Gondwanan and Laurasian Early Triassic taxa, such as Watsonisuchus, Wetlugasarus, and Parotosuchus. Nevertherless, they display some characters which have not previously been described in Mesozoic temnospondyls. The Permo−Triassic Uruguayan mastodonsaurids support a Gondwanan origin for the group, an event which probably occurred sometime during the latest Permian.

Todites lobulatus sp.nov.is described from the lowermost Upper Permian (Ufimian) of the Pechora basin.The fossil remains preserved as compressions and impressions, were collected from near−shore lake deposits of the Intinskian Formation.The species belongs to protoleptosporangiate ferns (Pteridophyta) of the Osmundaceae, and is characterized by tripinnate fertile fronds with deeply dissected lobate pinnules with round apexes.Sporangia are round or ovoid, free, and located on the abaxial leaf surface.A group of specialized thick−walled cells is located on the top or side part of the sporangia.The species is the most ancient representative of Osmundaceae. Spores of Osmundacidites−type, preserved in situ, are characterized.

Finds of juvenile parareptiles are rare in the fossil record. We describe partial upper dentition with large vacuities between bones belonging to a neonate pareiasaur (preserved skull fragment is 22.4 mm long). The specimen was collected within 5 m from a skeleton of an adult specimen of Deltavjatia vjatkensis (Hartmann-Weinberg, 1937) (Pareiasauridae) from red calcareous mudstones in the upper part of the Vanyushonkov Member of Ursulov Formation (Upper Permian, Upper Tatarian substage, Vishkil'skiy regional stage) of Kotel'nich locality, Vyatka River region, Russia. Referral to Deltavjatia vjatkensis is based on the presence of heterodont dentition: spatulate maxillary, triconodont vomerine and conical, palatine and pterygoid teeth located on well-developed palate ridges. This is the first positively identified record of the neonate pareiasaur dentition.
