To all,
One of the small pleasures I've recently enjoyed has been to purchase a
small vial of Devonian "conodont sand" from Stratigraphics for a few
dollars (Rich Hamell ). While sorting thru the
sand for nanofossils of conodont jaws and placoderm teeth (again using
Mike Blood's Russian stereoscope!), I'v come across several perfectly
spherical jet black grains with visible pitting and flow lines very
reminescent of Indochinites. It makes sense to me that these also
represent microtektites or ablated droplets of meteorites. One hour of
this microsorting has yielded three tiny spherules, all three very
uniform in size and appearance. I haven't even checked to see if
they're magnetic. I wonder what more could be learned from these tiny
treasures?? And I rather suspect that if more of us were to start
scrutinizing rain gutters and such, that these extraterrestrials are not
at all rare.
