[HTML][HTML] The phylogenetic relationships of basal archosauromorphs, with an emphasis on the systematics of proterosuchian archosauriforms
MD Ezcurra - PeerJ, 2016 - peerj.com
The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent
empirical case study to shed light on evolutionary radiations in deep time and the timing and …

CA-TIMS zircon U–Pb dating of felsic ignimbrite from the Binchuan section: Implications for the termination age of Emeishan large igneous province
The age of the Emeishan lavas in SW China remains poorly constrained because the

Dinosaur diversification linked with the Carnian Pluvial Episode
Dinosaurs diversified in two steps during the Triassic. They originated about 245 Ma, during
the recovery from the Permian-Triassic mass extinction, and then remained insignificant until …
