Which extinction event led to the breakup of Pangaea?

The breakup of Pangaea, which initially formed during the late Paleozoic era, is most closely associated with the tectonic activities that took place during the Mesozoic era. The Permian-Triassic extinction marked the largest extinction event in Earth’s history, occurring around 252 million years ago, and it set in motion many significant geological and biological changes, leading to the formation of new continental configurations.

Although the End Triassic extinction event, proposed as the answer here, happened about 201 million years ago and coincided with significant geological activity, including the initial rifting of Pangaea, the actual significant movements leading to the widespread breakup are more clearly associated with the aftermath of the Triassic and into the Jurassic Period when the continents started to drift apart.

The other extinction events listed, including the Ordovician-Silurian, the Permian-Triassic, and the Cretaceous-Tertiary extinction events, had profound effects on biodiversity but do not directly correlate with the tectonic movements that led to the breakup of Pangaea in the same context. The timing and geological evidence support the idea that the significant movements due to rifting and tectonic activities aligning with the Triassic period were influential in the early
