The impact of the Serpukhovian extinction on Ctenacanthiform diversity

[Joseph Fossil]

During the early part of the Serpukhovian stage of the Mississippian period, Carboniferous era around 330 Million years, a mass extinction occurred that wiped out between 13-39% of marine genera.

Its causes are still currently unknown and most marine genera groups recovered in the Pennsylvanian period. But I'm curious about the impacts this extinction event had on the diversity on Ctenacanthiformes and other Chondricthyian groups from the time and their subsequent recovery? What do you guys think?
