Tidal Effects of Passing Planets and Mass Extinctions [PDF]
, 1998 Recent observations suggest that many planetary-mass objects may be present in the outer solar system between the Kuiper belt and the Oort cloud. Gravitational perturbations may occasionally bring them into the inner solar system.

Volcanogenic Dark Matter and Mass Extinctions
, 1996 The passage of the Earth through dense clumps of dark matter, the presence of which are predicted by certain cosmologies, would produce large quantities of heat in the interior of this planet through the capture and subsequent annihilation of dark matter
