The results of palynological study of the Synya Formation (Middle Triassic) in outcrops along the Kydz'rasyu River banks are presented. The published and archival results of previous palynological investigations of the Synya deposits were used as an additional record. It was shown that the species composition of the palynological assemblage (PA) of the Synya Formation on the Kydz'rasyu River fully corresponded to the PA Converrucosisporites conferteornatus — Florinites pseudostriatus and determined the Triassic, Ladinian, age of the enclosing deposits. The results of reconstruction of the growing vegetation testified to the existence of rich and diverse vegetation in the Ladinian Age on the studied territory, where the flora of highly moistened biotopes prevailed.

ABSTRACT An unusual large teeth, finding from time to time in marine sediments of Muschelkalk, Silesia, Poland indicate the superpredators occurrence. According to size and morphological features the teeth are similar to archosaurs or giant marine reptiles.

Tetralophozia setiformis is a widespread species occurring usually without organs of sexual and asexual reproduction. Gemmae of Tetralophozia setiformis were observed for the second time in Russia and Eurasia in the Northern Urals, Komi Republic. They form compact masses over upper leaves. The compact masses consist largely (70 %) of immature gemmae. Description of gemmae and gemmiparous shoots from the Northern Urals and their comparison with those from the other known localities, namely British Columbia (Canada) and the Murmansk Region (European Russia) were carried out. The gemmiparous plants of T. setiformis from the Northern Urals have approximately the same width as plants without gemmae but they are shorter. The leaves of gemmiparous plants from the Northern Urals are similar to leaves of gemmiparous plants from British Columbia. The leaf shape in upper part of the gemmiparous shoots varies from the typical to ± modified from gemmae production. These leaf shape transitions include reduction of leaf size and lobe number from 4 to 2–3, suppression of development and disappearance of characteristic teeth at the base of sinus. Gemmae size (17 × 22 μm) of plants from the Northern Urals is within variability recorded for plants from the Murmansk Region and British Columbia.
