This article discusses a newly identified extinction event that occurred in middle Triassic. Mammals appeared at the end of the event, dinosaurs which were rare, became the dominant animal group. The cause was massive eruptions in what is now Northwestern North America, driving the temperatures up, rainfall down, and an extinction of existing terrestrial and marine plant and animal groups. For example, coral reef ecosystems became extant.

Well that's interesting and new (to me anyway).
Here,, by the way, is the original research paper, not behind a paywall:

Looking at the paper, 1,000,000 km^3 of basalt is about the same volume as the Deccan Traps

Smaller than the NJ Palisades, associated with the end-Triassic extinction which was 2–3M km^3 and of course the Siberian Traps, associated with the Permian extinction at 4M km^3
