This new timeline, the researchers say, establishes the Siberian Traps as the main suspect in killing off a majority of the planet’s species. However, if during the late Permian period the lack of dissolved oxygen is believed to be a consequence of a global warming (Zhang et al., 2018a), and during the late Ordovician period – a consequence of a climate cooling (Bartlett et al., 2018), what could cause it during other periods of mass extinctions is not yet clear.

The scientific consensus is that the main cause of extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [19] which released sulfur dioxide and carbon dioxide, resulting in euxinia and anoxia, [20] [21] elevating global temperatures, [22] [23] [24] and acidifying the oceans.Mar 15, 2023 · The three mass extinction events are highlighted in red with stars: P/Tr = end-Permian event, Tr/J = end-Triassic event, K/Pg = end-Cretaceous event.
