Abstract The aftermath of the end‐Permian mass extinction provided ecological opportunities for many groups reptiles, marking beginning reptile dominance Mesozoic oceans. Clades such as ichthyosaurs, thalattosuchians, sauropterygians, mosasaurs and turtles evolved a remarkable diversity niches became important components aquatic ecosystems. Locomotion is key aspect ecology, crucial biological f...

The mantle paleogeotherm under the Obnazhennaya kimberlite pipe (Kuoika field, Siberian craton) was reconstructed using chemical composition of clinopyroxene xenocrystals and FITPLOT program. lithosphere thickness 187–193 km surface heat flow 41–42 mW/m 2 were measured for at time magmatism in Mesozoic. found to be much smaller than that central part craton (210–230 km), where Paleozoic diamond...
