The Triassic-Jurassic boundary marks one of the "big five" mass extinctions in the last half billion years. In many of the exposed rift basins of the Atlantic passive margin of eastern North America and Morocco, the boundary is identified as an interval of stratigraphically abrupt floral and faunal change within cyclical lacustrine sequences. A comparatively thin interval of Jurassic age strata separate the boundary from extensive overlying basalt flows, the "best" dates of which (~202 Ma) are… CONTINUE READING
