Triassic–Jurassic extinction
Videos
The Triassic–Jurassic extinction event, often called the Triassic–Jurassic mass extinction or end-Triassic extinction, marks the boundary between the Triassic and Jurassic periods, 201.4 million years
Capitosaurs (such as this Mastodonsaurus) were among the major amphibian groups which became extinct at the T–J boundary, though many may have died out earlier.

The Manicouagan reservoir in Quebec, a massive crater formed by a Late Triassic impact. Radiometric dating has determined that it is about 13 million years older than the Triassic–Jurassic boundary, and thus an unlikely candidate for a mass extinction.

Dinosaurs are a diverse group of warmblooded reptiles of the clade Dinosauria. They existed through most of the Mesozoic era, first appearing early in the Triassic period. They became the dominant ter
Triassic–Jurassic extinction
…marine vertebrates, gastropods, and benthic foraminifera were relatively unaffected. On land, all archosauromorph reptiles other than crocodylomorphs, dinosaurs, and pterosaurs became extinct. Crocodylomorphs, dinosaurs, pterosaurs, and mammals were left largely untouched, allowing them to become the dominant…
