Evidence for Late Triassic crustal suturing of the Central and Southern Pamir

Journal of Asian Earth Sciences: X, 2020
The timing of closure of the Paleotethys and Rushan ocean basins and suturing of Gondwanan crustal fragments in the Pamir is not well resolved. Whereas the Central Pamir terrane is generally interpreted to have collided with the Northern Pamir terrane at

The fossil record of early tetrapods: worker effort and the end-Permian mass extinction [PDF]

, 2010
It is important to understand the quality of the fossil record of early tetrapods (Tetrapoda, minus Lissamphibia and Amniota) because of their key role in the transition of vertebrates from water to land, their dominance of terrestrial faunas for over ...
