[meteorite-list] Younger Dryas (pseudo?)-tektites

[MexicoDoug]

Hi List,
 
I was just curious if anyone has seen and has more information on; or 
better yet, can post a link to an image, of any of the enigmatic 
microtektite or microtektite-like things found in the Younger-Dryas 
Boundary, and referred to in West et. al., (where et. al. includes our 
respected listmember Ted Bunch):
 
 From their poster at the International Union for Quiarternary Research 
conference in Bern, Switzerland in progress at the moment, and to be 
presented tomorrow, Tuesday 26 Jul, from 14:30 to 15:50 in the Bern 
Expo2 poster hall:
 
"Shock-melt Evidence for a Cosmic Impact with Earth during the Younger 
Dryas at 12.9 ka"
 
"Some glassy objects from the YDB are aerodynamically formed into 
teardrops, dumbbells, and other shapes. These morphologies are common 
to microtektites and macrotektites from the Southeast Asian 
strewnfield, but are not apparent in micrometeorite collections."
 
Does anyone have a piece of this material - I'd love to see it?
 
Kindest wishes
Doug
