[meteorite-list] Periodicity in Impact Cratering ? Part 2

[Paul]

Hi,

Yesterday, I posted the link to apaper that argued
against there being a periodicity in Phanerozoic
impact cratering.

On the other side of the argument, I found some
papers that argued for a periodicity in Phanerozoic
impact cratering. They include:

Rampino, M.R., and K. Caldeira, 2017: Correlation of the
largest craters, stratigraphic impact signatures, and
extinction events over the past 250 Myr. Geosci.

Rampino, M.R., and K. Caldeira, 2015: Periodic impact
cratering and extinction events over the last 260
million years. Mon. Not. Roy. Astron. Soc., 454, no. 4,
