This was a blurb reprinted from the November 1994 issue of Sandia Science
News. It involves a paper by Mark Boslaugh et al , "Axial Focusing of Energy
from a Hypervelocity Impact on Earth".

Sandia super computer simulations now show that mjor episodes of flood
volcanism can be induced on the ANTIPODE (i.e. Deccan) side of the earth.

In fact the entire March issue of Geotimes is devoted to the subject of mass
extinction and a must read.

   Little, C.T.S.,  Benton, M.J., 1995. Early Jurassic mass extinction: A
global long-term event. Geology, v.23, no.6, p.495-498

Discusses an invertebrate mass extinction that followed an anoxic event but
occured over a long period of time.

Benton, M. J., and Simms, M. J., 1995. Testing the marine and continental
fossil record. Geology, v.23 no.7, p.601-604

Authors propose that the terrestrial fossil record iss as complete as the
marine fossil record is based on echinoderm data. Not exactly mass extinction
related but it does have a bearing on the completeness of the fossil record
and can have implications on the K-T debate and the Signor-Lipps effect.

Has anyone else read this stuff? What are your thoughts?
