The Second Catastrophe and Retreat

(p.179) Chapter 6 The Second Catastrophe and Retreat
When the Invasion of Land Failed

George R. McGhee

Columbia University Press

This chapter describes the End-Famennian Catastrophe. In the waning years of the Famennian period, vertebrates and arthropods once again began to die in greater numbers. On land, the huge forests also began to die. Population sizes of species once again dwindled until they vanished. By the end of the Famennian period, all of the known Famennian tetrapod species had perished. In land, most of the great lignophyte tree Archaeopteris hibernica died. Only a few of the Archaeopteris trees survived in the Early Carboniferous period, only to die soon thereafter as well. Out in the oceans, the ancient jawless fishes and the great armored fishes, the Placodermi, began to die rapidly. Both of these groups had lost half of their phylogenetic lineages in the end-Frasnian extinction, but their entire generic lineage did not survive the end-Famennian extinction. The cause of this phenomenon is still unknown up to now.
