Adam's paper: Huttenlocker, A. K., and J. Botha-Brink. 2013. Body size and growth patterns in the therocephalian Moschorhinus(Therapsida) before and after the end-Permian extinction in South Africa. Paleobiology. 39:253-277. doi:

But surprisingly few people are aware of an even greater event that disrupted links in communities on land and in the oceans during the Earth’s last major icehouse-hothouse transition about 252 million years ago: the end-Permian extinction. This event shared many characteristics with the K-Pg extinction, but with a much higher death toll, wiping-out nearly 90% of animal species. It is estimated that animal communities did not return to their former ecological diversity until some eight million years la…
