====Choiyoi Silicic Large Igneous Province====
A second flood basalt event that produced the Choiyoi Silicic Large Igneous Province in southwestern Gondwana between around 286 Ma and 247 Ma has also been suggested as a significant additional extinction mechanism.<ref name="JosefinaBodnar" /> At 1,300,000 cubic kilometres in volume<ref>{{cite journal |last1=Nelson |first1=D.
