The mesozoic
Anapsid, synapsid, and diapsid reptiles pursued very different paths toward the start of the Mesozoic Era. Today, the only living relatives of the anapsids are turtles and tortoises, though the exact nature of this relationship is hotly disputed by paleontologists. The synapsids spawned one extinct reptilian line, the pelycosaurs, ...The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all …The North China Craton (NCC) was originally formed by the amalgamation of the eastern and western blocks along an orogenic belt at ∼1.9 Ga. After cratonization, the NCC was essentially stable until the Mesozoic, when intense felsic magmatism and related mineralization, deformation, pull-apart basins, and exhumation of the deep crust widely occurred, indicative of destruction or ...
