Phanerozoic survivors: Actinopterygian evolution through the Permo‐Triassic and Triassic‐Jurassic mass extinction events
Actinopterygians (ray-finned fishes) successfully passed through four of the big five mass extinction events of the Phanerozoic, but the effects of these crises on the group are poorly understood. Many researchers have assumed that the Permo-Triassic mass extinction (PTME) and end-Triassic extinction (ETE) had little impact on actinopterygians, despite devastating many other groups. Here, two m...
متن کاملCauses and Consequences of the Triassic-jurassic Mass Extinction as Seen from the Hartford Basin
One of the most severe mass extinctions of the Phanerozoic, the Triassic-Jurassic event is greater or equal in magnitude to that at the more famous K-T boundary (Benton, 1994) (Fig. 1). Such severity, at least for marine families is also supported by Foote’s (2003) statistical revaluations, although there remain dissenters (e.g. Hallam, 2002; Lucas et al., 2002). The cause of this mass-extincti...
متن کاملTriassic-Jurassic mass extinction as trigger for the Mesozoic radiation of crocodylomorphs.
Pseudosuchia, one of the two main clades of Archosauria (Reptilia: Diapsida), suffered a major decline in lineage diversity during the Triassic-Jurassic (TJ) mass extinction (approx. 201 Ma). Crocodylomorpha, including living crocodilians and their extinct relatives, is the only group of pseudosuchians that survived into the Jurassic. We reassess changes in pseudosuchian morphological diversity...
متن کاملNew early Jurassic tetrapod assemblages constrain Triassic-Jurassic tetrapod extinction event.
The discovery of the first definitively correlated earliest Jurassic (200 million years before present) tetrapod assemblage (Fundy basin, Newark Supergroup, Nova Scotia) allows reevaluation of the duration of the Triassic-Jurassic tetrapod extinction event. Present are tritheledont and mammal-like reptiles, prosauropod, theropod, and ornithischian dinosaurs, protosuchian and sphenosuchian croco...
متن کاملOcean acidification and the Permo-Triassic mass extinction.
Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event is lacking. We present a high-resolution seawater pH record across this interval, using boron isotope data combined with a quantitative modeling approach. In the latest Permian, increased ocean alkalinity primed th...
