I'd be happy to write on the Jurassic conifer log situation when it is
all resolved. One idea is to get a grant for some heavy machinery to
dig up a large log, take it away and araldite the pieces together for
a museum display. May not happen tho. Meanwhile I've had not one but
two strong leads on Tertiary silicified wood (eucalypt, casuarina)
with a superb black and yellow tigereye sheen. Hopefully all sorted
out by Xmas.
