Dear Friends,

There is a new paper that proposes an interesting and novel
idea about the selectivity of the Cretaceous-Paleogene Extinctions.

It is:

Kikuchi, R., and M. Vanneste, 2010, A theoretical
exercise in the modeling of ground-level ozone resulting
from the K–T asteroid impact: Its possible link with the
extinction selectivity of terrestrial vertebrates.
Palaeogeography, Palaeoclimatology, Palaeoecology.
vol. 288, no. 1-4, pp.14–23.

A somewhat unrelated and downloadable PDF file about
about "meteorites, impacts, and mass extinction" is:

Meteorites, Impacts, and Mass Extinction
