Phil Nicholls (pnich@globalone.net) sez:

`Potassium/Argon dating is only really good up 500,000 years ago. This
`has recently been a problem for paleoanthropologists because there
`have been few good dating methods for the important transitional
`period between 500,000 and 100,000 years ago.

This seems to be the region where these electron spin resonance dates
are used. Does anyone know how reliable they are? I suppose we'll
now see a flurry of announcements as the technique is applied to
all the existing fossils from that period.
