Extract

First, I would like to congratulate Wang et al. (2014) for their important work on the dating of the Panxian fauna, a Triassic fossil Lagerstätte that has produced many exquisitely preserved marine reptiles (Motani et al. 2008) and that marks the full recovery of the marine ecosystem (Jiang et al. 2009) following the Permian–Triassic marine mass extinction (PTME). Papers by Wang et al. (2014) and alike are especially welcomed by vertebrate palaeontologists since they provide precise dating results for some of the most important vertebrate fossils in the world, such as the bizarre protorosaur Dinocephalosaurus orientalis (Li, Rieppel & LaBarbera, 2004) and the earliest marine archosaur Qianosuchus mixtus (Li et al. 2006). This related topic is also interesting because of the very recent debate about the timing of recovery from the PTME, the largest biodiversity crash during the Phanerozoic, from the predators’ perspective (Chen & Benton, 2012; Scheyer et al. 2014).
