The article you linked had a table with mass extinction events, true. And if you look at the reference it states "Partial list from Image:Extinction Intensity.png"Partial is not everything. Added to that the chart, when you look at the list, says specifically...

" Note that these data do not represent all genera that have ever lived, but rather only a selection of marine genera whose qualities are such that they are easily preserved as fossils."
