That sounds rather close to the end of the Jurassic, which did
involve a certain amount of extinction beyond the normal levels.


Check the article:
        Leary & Rampino, 1990. A multi-causal model of mass
        extinctions; increas in trace metals in the oceans.
        IN Extinction Events in Earth History, Kauffman &
        Walliser (eds).

This article has a table of all of the Mesozoic mass extinctions,
and the associated flood basalts they knew about.
