Decoupling of morphological disparity and taxic diversity during the adaptive radiation of anomodont therapsids [PDF]

, 2013
Adaptive radiations are central to macroevolutionary theory. Whether triggered by acquisition of new traits or ecological opportunities arising from mass extinctions, it is debated whether adaptive radiations are marked by initial expansion of taxic ...

Sedimentation conditions and clast transport during the formation of sedimentary paleobasins in the north of Irkutsk Oblast and river network formation

Известия высших учебных заведений: Геология и разведка, 2023
Background. Changes in the composition of clastic material reflect changes in both the paleogeographic environment and clast transport paths. In turn, this indicates changes in the conditions of regional development.
