Summary

Description
Deutsch: Trias-Jura-Massenausterben (eines der „Big Five“) am Beispiel der stratigraphischen Reichweite einiger Tetrapodenfamilien: viele Familien der Temnospondylen, Therapsiden und basalen Archosaurier verschwinden spätestens an der Trias-Jura-Grenze, während Lepidosaurier und die meisten Dinosaurierfamilien (letzgenannte gelb markiert), die in der Obertrias auftauchen, sich in den Jura hinüberretten.
English: Triassic-Jurassic boundary mass extinction (one of the “big five”) exemplified by the stratigraphic range of some tetrapod families: many temnospodyl, therapsid and basal archosaur families disappear at the Triassic-Jurassic boundary whereas lepidosaurs and most of the dinosaur families (the latter ones highlighted in yellow), which appear in the Upper Triassic, survive into the Jurassic.
