[meteorite-list] Paper About Using Exterrestrial Impacts to Explain Mass Extinctions

[Paul H.]

Below is a recent paper about the evaluation of extraterrestrial
impacts in mass extinctions, which I found both thoughtful and
an interesting read.

Racki, G., 2011, The Alvarez impact theory of mass extinction;
limits to its applicability and the “great expectations syndrome”
Acta Palaeontologica Polonica, vol. 57, no. 4, pp. 681–702.
